I know I’m a little late to the party but I really appreciate that you share your hard earned knowledge ! Especially that oiling mod ! That chamfering has to make such a difference rather than that sharp edge ! Just makes sense. Take care Todd 🍺🍺

Nice clean build for sure. That has to be the most worn out dingle ball hone I have ever seen. That's awesome.

Had 88 650 ported and polished decker pipes Turned it 9200 rpms for 7500 miles never had a problem I set the oil pump richer than the stock marks

Love the honing trick in the parts washer! Never seen it done before going to try it one day for sure! Great build and detailed tips. Also oil mod seems like a great idea! Great video Todd! 😊

May you have clean and happy mineral spirits. 😆

This is going to be a fantastic series there Todd. I don't have a 650, yet. Shhh, don't tell the wife. 😂

I had a 650 with SLP pipes, then 95 XLT 600 no pipes. I kept blowing the motor on XLT, but my 650 was still going. Eventually i went with the two cylinder lyberty motors. those 650 are pretty reliable in my opinion. the coolant bolts above manifold would strip out here and there. one time my pto pipe shifted and melted the coolant hose, glad i begin smelling the hose melt under heat tape foil.

I always let every engine warm up,always

The beard is looking epic. Santa Polaris from the great white north.

Had a 89 500. First Polaris. Crank bearing failure at 2800. I think. That has always been a Polaris problem. Oil journal's are to small thus failure. My opinion. Your doing it right. Last much longer. Once again being a faithful Polaris guy .

Thanks so much for sharing your experience and knowledge

Can't wait for the next video

RXL was a good sled left stock but piped idk of one that ever ran right. Lot blew up if not maybe all of them. My father and i use to build 650’s bran new. Triple pipes porting milled heads. Some we just piped took a lot of knowledge in jetting abd clutching to make them run right. Never new of anyone that counted on a dealer that was happy after. Most the time blow up idk how many times i saw it happen. The pipe manufacturers jetting specs never right always lean sometimes really lean. So we blew a few up in the beginning learned to jet pig rich work ur way down. Found out with shitty clutching ur jetting will never be right. Trial and error always the best and patience don’t except perfect results the first time putting a mod sled together. I remember jetting being 2-5 sizes bigger than pipe manufacturers recommendations. Our clutching was never what they recommended either maybe some of it but never all. Like watching u work on the old triple Polaris’s what i grew up on. Snowmobiling was a different world back then lol!!

Great video, appreciate you showing all the hard work that goes into a proper rebuild. Your passion is a joy to watch.

Great video Todd! One of my favourite motors!!! Really looking forward to this engine build series 👍 Keep up the good work! Cheers 🍻

Hell yea, keep up the great work buddy 👍

Simple with purpose wins the day! Great work as always Todd , Cheers!

I wish these types of videos were around when i had my 650 indy. Would have saved me so much money and time. Nice job Todd! Cant wait for the next one! 🍻

Love this! Great detail in this video. God I love sled videos.

Great work man 😊

The triple king 👑 love the video man. working on my RXL still taking a little longer but having fun with my son doing it

Todd, just looking at my 01 587 case and you could champher the oil hole on the bearing side of upper case towards the PTO and MAG side of hole underneath to let oil get to outer side of bearing much better. Plus like you did, champher top side of hole too. Pto end one could drill down further in the square to get rid of TROUGH and then blend that towards left side of case ( looking at it from carb side of case ) to channel oil to bearing. My case has the oil line spicket already from factory. Also there is no reason you can't use a Bridgeport to cut a 570 to fit extended cylinder 650 cylinders. I believe ( not having one to measure) you would only be taking off .015 to say .020 per side( total .040 " ) and there certainly is enough meat to do that with. Just a thought for you as I sit here in 40 deg Florida weather. Lol. Have 3 P's in my garage down here. Never thought I'd stay so long. 31 years ! That's 29 years too long lol. I've got a 91 500 indy almost pristine ( 3600 miles on her as I remember), 99 XC SP 700 ( Johnny Cash special ) littering! And a 2003 Edge with a XCR 800, Fusion skid Walkers and Fox dual shocks up front from an 01 440 . Wish I were up there with the tripples and tripple tripples. Jonsey

Thanks for video. I am buying a nice 650 with blow engine. I Am going to build it right and then I’ll know what I got.

Great video cant wait to see how this 650 turns out. Hopefully we can get some rideable snow soon cuz this sucks

Good stuff Todd.

🔥you sure do good work.. I like those lil oil updates, sure going to help that pto side eh. 16” Snow up here in north Bay Area, groomer made a pass on Sunday, how snow out your way 🔥👊🔥🔨🏍⚠️⚙️

Thank you Todd on this

Great video!

Great video

I had an 88 650 and put 12,000 miles on it. Never any problems. It still had 120 lbs in each cylinder. Also , didn’t the newer cylinders have larger transfer ports ? I always checked oil pump settings. Even brand new sleds. And , yes I found some on the lean side.

Lol same for me im building a 91 indy 650. I pulled apart I think it was 6 motors looking for a good crank.

Another good video Todd..you guys getting snow ❄ yet

Good video. I was looking at my shop my solvent is very flammable. A drill with Sparks I don't think that be good

Great info.

A+ as always. Gotta ask, what cleaning solvent did you buy for your parts cleaner?

Have you thought about trying to find some old SLP DZ? And or RZ parts to put onto one of those for a late 80s/early 90s lake/trail mod? Resto runner

Would you remove the cylinder studs to clean up the bottoms end with the sandpaper as well ? As always great videos ❤

I just finished a rebuild on my 96 RXL 650

i got 3 of them motor and my argienal crank whent in it and i bout another one and found out it had a hair line crack in it and bout another all togather and running and there an awsome motor been throught a lot of over the years but tuff tho to me if treated right just hard to find over here in canada iam like the only one that i know of that has one and i have talked to alot of people about it and they never siad they had one

Great video,, what grit was the sandpaper you put on the bench to clean up the heads? I'll be building my 90 650 engine soon

Nice one Todd! Are the Indy 650 and RXL engines different other than carb vs EFI?

Great video but It’s not a Todd Clyne video without a beer crack.

Some things are designed to fail it creates a parts market.

Is that 650 made by Fuji or who? What do they say about mods to case oil passages? My bro was an assy line inspector in Roseau and I think he had a big twin 700 or 800. He had no problems that I know of but did say the triples had some. Like center carb having no main jets in some .

Do you chamfer the bearings to try and match the block? I don't even know what the bearings look like, just a thought.

I am having problems pulling the flywheel off my 650. I have a Kimpex puller. I will not come off. It will brake the puller before it even moves. Wondering what I may be doing wrong.

Whats the best bore size to go with if you were to bore out a 650 indy 2 sizees or 3 over ??

@toddclyne where to get new complete crank for xlt597cc triple single exhaust motors
