Nice. He told me to go with a ripsawII track. I bet i can go through more with this then an old 136 track?! This track digs and claws!!

Ha thanks!

The old 670! Remember brand new 670 twins, they were mean!

@@jonstevensmaplegrovefarms3754 you ain't lying, especially the Mach 670's with the factory twin pipes and the H.O. too. First "big" sled I owned was a 97 mxz 670 back in high school, live in a very small town (pop. Maybe 1200 people) and rode it to school everyday i could, felt pretty cool being the only kid that could hold the skis up and spanking my buddies during lunch breaks. We raised some hell in that small town, they quit letting kids off campus for lunch after my class graduated......sorry kiddos 😁

Nice!

Pretty bad that i am riding a sled that 20 years ago was cutting edge?! 2001 was the first year i raced!

Thought the '99s had the Aggressive chassis? Maybe one and the same with different terms? At any rate, the '99 800 XCRs were the slowest model year 800 XCR sleds, as delivered from Polaris.....

The Polaris RXL also a very unique sound of their own also. Especially if you put a set aaen or SLP pipes on them. Love them old piston port engines.

Thanks for joining! What part of Michigan?

@@jonstevensmaplegrovefarms3754 wow sorry for the late reply lower Michigan south of Saginaw .

Ok! Yeah i used to be on the forums a lot. Then we hit a 10 year snow drought and life changes.

No doubt and everyone likes to do it under the sled. While on its side good time to fuss with gearbox.... no mess.

@@plowmaster1206 Yea. Take the 2 bolts out of the side your rolling over to first. It made one of the worst jobs to an easiest one. Especially with studded track. I think I read it in Clymers repair manual. Waiting for snow when I was a kid I read the repair manual cover to cover😂😂

Yes and after a few of em in a row, changing a track is easily done in less than an hr. Last air polaris i did i had track out in 15 min. The most time consumption usually comes from one side of the skid bolts fighting the other. I get it in the air and spin em out to a few threads before i tip it over.

Thank you very much. I always have big dreams and plans of all the fun videos I could be making, and then life really gets in the way. LOL

Thank you man once again, please, post more video , i shall tell all my buddies to sub to your channel. Thank you.

Ha, thanks

Every northern US states with mountains

@@alaskanzombie9075 we as in Jon and I live in Minnesota no mountains here lol just lot's of mud puddles ! 👍😂

Nothing wrong with that 700 Liberty. Have said a few of them up way back when.

I have another channel for doing snowmobile stuff that I will start getting back to making videos pretty quickly

Lol thanks. Been working these triples over for 20 years,the Cheeta!!

Artic Cat had Cheetahs Panthers Panteras and Their first liquid El TigresYeah I am old haha.

Bolens, Cat, Speedway, and several other now defunct brands had triples long before Polaris released the Centurion, some as long as 10 years before the Centurion was released. First big triples for retail sales, iirc, were the 793, and 650 Hirth. Bolens came out with German built proprietary triple, and so did Brutanza (Brut)/Scorpion.....

Lol.

Lol. Had a kid bring a dirt bike with twisted crank. Big brass hammer, welder and dial indicator and some time engine was together and never heard back!

Ha. Yeah so much has changed. 20.years ago you had a couple sled magazines that had dozens and dozens of aftermarket companies. 90% are gone now.

I was always amazed at how fast the mechanics at The I-500 race could drop a suspension. They always laid the sled on their sides too.

@@thatmodshop7160 did you even watch video, sled on it side . I laugh at people like cuz you are couch mechanic experts .

I can do it both ways, on its side or flat using the hoist or lift, takes me about the same time and is similar job.

@@funtyes1970 the video cut out on me I put it in watch later and still wouldn't work so that's all I could see at the time 🤷‍♂️ I am a mechanic by trade what works for some may not work for others there are a multiple ways to get a job done, most jobs are very easy to beat book time, but at the end of the day it all comes to experience and trying different things 😎

@@funtyes1970 took you a year to come up with that, not relevant anymore 🤣🤦

Who ever had before me also drilled holes in the secondary to change the tension kinda like how the helix is with diffrent holes,got the sled at whitestar auction it came from Indiana from slenker marine in New haven had dyno ports on it and the numbers 460 on the windshield and msdra stickers on it maybe some racers from back then remember the sled,I got it for 1400 had pipes on it so nobody was bidding on it lol

@dirtyfacegeorge9938 funny you mention it. Talking to some other guys there is that conversation going on.

Nice! Heck of an engine!

99 is a little heavier. for trail riding, I would set it up pretty much the same. if running against a radar or timing a system, you could probably use the same setup or maybe have to gear slightly differently?

Ok thanks, I imagined they should be close on setup and me being lighter than most guys I know helps me out in the weight department a bit at least. Here we usually just bomb around on the little machines in ravines and whatnot. I just plan to have this one for some friendly family drags and some adrenaline rushes a few times a year, won't see 100 miles a year on the xcr. My older brothers used to do some drags in the mid 90s running doos and cats successfully and we like to brand jab back and forth, they would say Polaris is synonymous with slow so it would be fun to give them a surprise haha.@@jonstevensmaplegrovefarms3754

No radar runs or track videos to prove it.

Yep. Not really a wrong way. Next time I will have to do the chain case, need to put the seal in.

That's a good number! He had a similar porting but he didn't work the triple boards as big as I do. I got along good with Don I like him it would have been neat to meet him 20 years sooner in life

I don't think there's a really right or wrong way. When I use the Hoist or a sled lift on the rear skid I have zero labor involved and it's fast. When you have four Drive Wheels for me it's just a lot easier, faster to remove the bearing and drop the axle then go the other way grilled depending on the chassis if you have four Drive Wheels you might not have enough clearance to go the other way and get the shaft out of the chaincase

That's just importing that was used in my race sled so I thought well let's just bring it over to the trail sled. Surprise performance Engine on my race sled that I built but they sent a diagram for porting. A lot of companies ended up using that porting design for their race engines

Yes pro 5 was up there, great times back then!

I do, next fall i will open the shop back up and start doing sled work. Search madcow got speed racing and you will see my other channel i just started

@@jonstevensmaplegrovefarms3754 ok sounds good John thanks

Stock secondary with weights dialed in the rpm 24-37 might get you there 25-36 should get you there. If this is a trail track with trail studs i wouldn't worry about 130 its not going to happen. Track will hold you back. That speed is a chassis thing not hp. Your going to want to have that thing roll nice. On clean ice with engine idling you should be able to put your foot on the rear bumper and push it. Low windshield, tight clothes, tucked behind windshield, dish soap all over the rails, speed track set tight. Start making runs and fine tunning

i need more description of the port you are talking about. bottom of cylinder where it meets the case? intake ports, back one?

@@jonstevensmaplegrovefarms3754 Thank you! for the quick reply. Yes bottom of the cylinder. If you stop your porting vid. right @ 4.00 mins it's that port.

the one right above your finger @ 4:29 mins

@@cameronhedayat504 the one on the bottom of the skirt? i have cleaned them up myself but never really got to worried about them. have seen other guys cut them off, or spend a lot of time working on them,

@@jonstevensmaplegrovefarms3754 Thank you! Jon. I was out there mocking it up. And I figure the purpose is to have a cleaner shot out of the reed box. The piston skirt rides across this area. So I won't cut it off. Thanks again for the great video. Happy Sledding!

The Indy chassis 680 with a single pipe was an awesome sleeper sled. Drop the heads .010", do just a little bit of cleanup on the case little bit of cleanup on the bottom of the cylinders and in the port openings, vforce Reeds, gearing more aggressive in the chaincase, are 12 silver blue hole three in the back maybe hold to, adjust the primary weights to dial in your RPMs and toss on a 1-inch hacksaw track and that's LED hooked and booked

That engine has a lot of torque curve to it. I think I ended up at 2138 or 2139 gearing somewhere right there. I rent 2538 for a lot of years on the trail and on the ice and had really good luck with it. But it's all in your setup. There is no magic gearing. You could take the same sled and with 2538 gearing and dominate your buddies in 500 ft. You take the clutching and jetting out of that sled and give it to a different guy and is clutching and jetting might not be able to compete against your buddies in 500 feet. 4 drags with the Buddies if they're going to have somebody standing at 600 some odd feet to be the finish line clutching gearing and jetting is meaningless if all you're doing is spinning bad at the start line. An XLT with ice picks in 500 feet would easily beat a poorly set up 800 xcr that is just spinning

Jon Stevens Maple Grove Farms i appreciate the reply thanks for the good information!

Usually the opposite But it depends where you're starting. You need enough gear to reach your goal

I am in Rock Creek, where abouts are you?

@@jonstevensmaplegrovefarms3754 Down in cottage grove but travel to grand marais for sledding pretty regularly. so...local "ish" lol

@@sleddarcheddar yep!

@sleddarcheddar you didn't just have a sled accident did you?

Nice!

Went by twice. Thats why the snow is melted!!

Lol

@@jonstevensmaplegrovefarms3754 😂😂 love your sense of humor 🤣🤣

A lot of them old companies are out of business. It could be anybody's spring. You almost use a bathroom scale to get the compression rating and then an old bar or Beam scale torque wrench just see what the rotational twist is on it. I used to put together kits for people but if you go to hardcore sledder in the xcr section and tell him what you have for primary weights primary spring and a helix people can find you a good secondary spring. I personally think for trail riding the stock secondary was really good.

@@jonstevensmaplegrovefarms3754 thanks for the reply Jon

When I did my 1000 I thought it was 135 intake and 200 exhaust on a timing wheel. 800xcr would be almost identical on intake, just little less on exhaust. Did I set squish at .047 ? I thought so. Would have to measure again. With the triple ports I marked the pistons to where they open up around the wrist pin, drew that line on the wall to make sure I don't get leaking

@@jonstevensmaplegrovefarms3754 .047 sounds like you could delete base gasket? I'm doing a 700 triple soon ill post numbers back

I wouldn't but others have with aftermarket cylinders. Would have to relieve heads then, exhaust would become little low without porting.

@@jonstevensmaplegrovefarms3754 would .025 suffice for squish?

@plowmaster1206 doubt it? Piston might contact head. Back when I was doing mine I was told .045 was about as tight as you wanted to go.

For a trail sled in the off season you can pull the engine down, open up everything on the bottom of cylinder and top of case a 1/16" basic dremel tool can do it, then set each cylinder on top of the case and look up to make sure case and cylinder perfectly match. If you know you always have good gas you can drop stock heads .010" Honestly for trail riding stock engine, 22/40 or 21/39 gearing works great for heavy trail tracks, 25/38 gearing works real good for big wide open trails and rivers. Stock clutching is really good for trail, Jet closer to the day, you dont need 440 mains for last week's-30 this week when it's +25 Suspension adjustments and track improvements are big, why have more engine hp if you digging trenches.

Also, even in a trail sled, why would you ever run a track that is not studded? Not just for acceleration, but for breaking.

Where are you located? I have a guy who might be working on them? I cant promise i will have time for sled work

@@jonstevensmaplegrovefarms3754 im located near Toronto not far from iantomasi

Pretty sure they could help you out?!

Could have been.

Keep it! Stock pipe, hacksaw or ripsaw track, stock primary clutch, drop 1 tooth on top sprocket in chainsaw, 50-36 helix and silver blue polaris secondary spring start in hole 3, jet closer to temps.

I don't know what you're talkin about.

I am him!

@@jonstevensmaplegrovefarms3754 I've been saving so many of your recommendations from online forums with regards to the XCR 800! So many tips you've given have helped me. I have a TZR hot trail ported xcr 800 with stock pipes. I have 2 sets of SLP pipes (one brand new, still in packaging) and want to use them but based on your suggestions, I just sticked it out with the stockers.

The stock pipes are just great pipes. Iran SLP pipes and could not get them to work. Was on the phone over and over and over again with them about that they won't pull the clutching that they should. I took off the muffler welding some individual silencers to the pipe and then they worked. They sucked gas big time but on the ice track they did go faster

@@jonstevensmaplegrovefarms3754 do you think I could use the stock muffler to bypass the SLP muffler issues you had?

When i was a kid i worked at an airport. Lol. I was the rivet holder. I would lay inside and push the rivet out and put a block against it, the guy outside would hammer it!

We always called him a triple triple because you had three cylinders and three pipes where the ultra and the XLT triple cylinder into one pipe

Triple triple is triple cylinder triple pipes has nothing to do with individual cylinders or mono block.

@@eriklokken5650 triple triple has always ment 3 cylinders and 3 pipe end of story you have gotten some incorrect information from someone

@@bobc8694 that is what I said Bob triple cylinder triple pipes. Was that message for Tom?

@@eriklokken5650 yes I posted it on the wrong one you can tell the guys that have been around sled's for awhile and the one's that think they have when they say dumb stuff monoblock or not 3 cylinders and 3 Pipe's triple triple you know but ya that was for that other guy not you have a great night... Bob....

Nice!

Agreed, had a buddy with a 99 xcr, Flannery built 217hp was an animal on the track nothing beat it.

Looking at the 20 years of advancement made on the 800 twin, went from 135/140 hp to 155/160 hp and now with the 850s around 165/170 area think of an 800/900 triple with the same advancement in porting and pipe work, electronics. 190 hp stock would be a very real number?!

I got to ride a 2019 and that is nice. When I got off of that new machine the old xcr was like that Hemi Cuda with no AC no power steering and a vinyl bench seat and making a small Loop on a Sunday Drive was nice but if you went down to the metro and drove in traffic and came home you were pretty tired. But somehow when that sled was new we put on hundreds of miles a day. You'll never see one make 210 horsepower with no Turbo. That old Fuji still gets it done!

@@jonstevensmaplegrovefarms3754 thats like comparing the old muscle cars that can't keep up to the new technology your sled will go stupid fast down a track but in 98 cat made a 1000cc that would eat these xcrs alive. If you twin pipe a twin cylinder short track you will pass these ancient relics. However if you put one of those old triple motors in a new chassis you will never see that sled again lol

Raced many t cats at the radar runs 20 years ago. Traded lots of win. It was fun. These new sleds are quick, the last couple years they are finding some top end. An indy 800 or dragon 800 stood no chance in 660 against a good xcr. Go for speed it got even better. Didnt make sense on paper the xcr should have lost by a mile. Old chassis were slippery, this new sled is the first one that might be able to go fast? Trail.stock xcr 800 is 112 mph in 1000 feet, same guy tunning these new sleds isnt there yet.

Time will tell if todays new sleds still around in 20+years and loved like the xcr800 still are after 20+years, and still RUNNING strong..

Had an xcr 800 in an IQR was fast justbdidnt know what I had young and dumb at the time lol I'm building a 780 mach z in a stripped lightweight RT 1000 chassis with Rotax Electric Reverse going to be great 👍

That'd be nice! I have a dragon chassis that I started to put one of these engines in then life got in the way

@@jonstevensmaplegrovefarms3754 i did it with my 99 xc 700 twin and it is the best idea ever. My ultimate build would be a 680 ultra those are my favorite polatis triples other than certain years of the storm

I love the fuji bottom end. So far have over 13 years of racing a 1000 top end kit on the ultra/xcr bottom end. Never let me down! Need to find time to get the angry dragon done for next winter.
