-"Hey louis what you draggin behind your sled??" - "Oh thats just my parts sled! Never know what youll need to fix!"

"If you're on the trail and need to change a piston"

The singles can go forever, maybe next time I'll put duals in it, we'll see. Thanks for watching!

If you don't have assembly lube, just as easy to use 2 stroke oil.

Good job! I swapped my pistons on a triple this summer and I wish I would have thought to use a pen to get those clips in.. what a pain in the thumb!

I have used a shop vac in the past to suck out the coolant, it helps in reducing the amount that drops in.

pull the head off, cylinder off, replace piston, replace fluid, get out out bush! We carry lots of spares and tools and keep them close to where we sled.

Thanks! Probably an IQR, starting to gather parts later this winter - for a summer build.

Right on - lets see that elan!

An IQR mod would be the best! I am hoping to mod out my IQR this up coming summer (if the budget allows it) and it would be really helpful if I could base it off your instructions! Keep up the great videos!

i wanna say all 700 and 800's have the non caged bearings. its a pita to put those back in. atleast you got the caged bearing for your doo!

Were not so lucky with snow here, I'm hoping you get out with you new sled, and make some videos for us to watch... I'm hoping, I'll have enough snow too put my own video on the tube...

yup - should be fun! just deciding on a motor.

Missed the ring gap 😳

Thanks I appreciate that.

Love you channel! Wish it was snowing already lol. Just got a mxz and dieing to ride. Cheers and c u on the trails 😊

Right on - well staty tuned - but I won't start till the summer!

This sled is similar to mine and you make it look easy. I know I'm going to change this on mine.

Nice video, the cyl bolts need to be tighten to 31 ft/lbs if they are the 10mm bolts.

Thanks for the video. Some nice tips there. Need to do one on my '93 Phazer.

No start up man I was anticipating

good video for someone like me trying to learn....Thanks!

Just like rebuilding a 2 stroke dirt bike(:

A video on syncing carbs would be great!! Thanks

Just noticed the Ottawa logo on the magnet,I'm from South Ottawa.

Not this time around - this summer I'l do a bunch of work to it.

I lost my pisten on clutch side the 2 pistens are good bud the left one on clutch is done

gobs of power and long track, either 800xcr motor, thundercat 1000 motor, maybe a watercraft motor, or 800 top end, havent decided.

i have a stock 250 elan beater, 540 monster elan, xlt mod, 700 doo mod, I also have enough to make a tundra and another elan not running. Iqr this winter probably, then mod it like mad.

it's an uncaged bearing, there wasnt anything wrong with it - just not caged.

The bearings in the older 700's weren't caged, the replacements are caged.

Yes, also check the ring gap and always use new gaskets.

a looped over zip tie also works well for removing springs, you can do it with one finger

thanks!

great video I ran out of Characters thats the first

Yes.

i just helped my dad rebuild his 380 ski doo new pistons

all doos have the non caged bearings.

Good idea!

Nice ring gap!

Well if you need to run 100LL or race gas then do it because it's cheaper, it is actually Avgas, not jet fuel, jet fuel is used in turbine or turbo prop aircraft, you probably know that. I prefer to only use high test with my builds, makes finding fuel easier - and a little cheaper. Maybe you can find used heads if you want to go cheaper?

lets ride that's all that matters.

Learned a lot thanks

your rebuilding a 2001 formula 700 right

Change a piston on the trail 🤔🤔

use oem if you can - and can afford them.

looks totally different then before! keep em coming! what would you say about running 100LL (low Lead jet fuel) in my 2004 ski-doo rev 440? it has high comp heads and low comp ones are $189 a piece and race gas is $12.87 a gallon at my local dealer/race shop. jet fuel is $6.54 a gallon. what would you say?

Were the rings clearanced properly before installation? It wasn't shown in the vid...Thats why I ask.

IQRs R BEAST!!!!!!!!

Nice work!and the next project is? :)

In your opinion what would be better to use, SPI cast pistons or Wiseco forged. People say forged is better but theres a whole bunch of machining to be done. Cast is just throw in and go. Just wanted to know what you think.

While i was helping my friend change pistons on his mxz 583 one of those retaining clips shot out and hit just beneath the rim of my glasses and man i got to tell you one thing those fuckers hurt!

IQR mod sled.

Oh dear! then I really have something to se! :D

what are you going to do with the iQ long rack it and such or are you going to male gobs of power/

Can you put isoflex on the crank bearings while you do this?

Can a top end be done on a 2006 Rev 500 with the engine in, or does the motor need to come out? Just planning for the eventual day a rebuild is necessary. Looks like this sled had a lot of room to work.

Why did the pins in the wrist pin bearings fall out? I dont get it.

What was the compression after the rebuild? What should it be on a 2002 700? Mine is around 125 on each side

Just bought a 2002 Mountain Cat 600 efi. When I bought it it ran very well and had 125 psi both cylinders; 2900 miles. Ran it for about 5 miles at home perfectly fine then it started smoking horribly. Coolant is getting into the cylinders and leaking between crankcase and cylinder in one spot. Planning on replacing all gaskets. Funny thing is that this sled had cylinder work and brand new gaskets 200 miles ago. Any suggestions or recommendations?

I'm looking for advice on what year motors I can swap into my 1995 600 XCR Polaris. Such as what other years will fit. I want to stick with the 600. I've located a 2000 600 xcr. Hoping it will work. Thanks in advance.

I have a 2002 MXZ 700 Sport with RER. It had low compression so I rebuilt the top end. Now it won’t start. Any suggestions?

Where do you get that royal purple assembly lube from there powermodz??

where did you get that hood?! thats sweet

Do you really pre-mix your fuel to trail ride? I guess you trail ride differently up there than i do at home. That sounds like a huge PITA for me.

nope, swapped em in and that's it, 130psi compression before breaking them in.

why didn't you show the spacers for the old wrist pin needle bearings

Hey guys....I follow you on youtube and came across this video. I was searching fro info on doinga top end on a 2002 Seadoo 717cc.. You guys make it look easy. Would this be close to what you guys did here? It is a rotax and I would like to just do the top end. Not sure what I would be getting into. All other information had the engine completely removed, not sure I want to get into that. Whats do you think?

What ever happend to this sled. I cant find any riding videos just the build?

Question, Why did't you go with MCB Dual Ring Pistons With Moly Rings?

I would not recommend 100LL with a race head. I run 100LL in my watercross mod but keep the compression ratio bellow 14:1. I beleive the race heads are 15 or 16:1, not 100% sure. That is too much for 100LL and it will detonate and eventually fail. Run c-14 or get new domes and run pump gas.

Did you have to hone the cylinders before putting in the new pistons?

Are the rings already gapped?

Im doing this to my sled so with the caged bearings i dont need the washers that fell out? Im buying the same kit for a 600 h.o rev also do the rings need to be put on a certain way?

How do the SPI pistons you're installing hold up? I've heard 50/50 good and bad news with them. Now, you from experience I am in need of pistons. Would you recommend these as a good, cheap, lasting piston? Thanks.

Hummm my bearings have never not been caged nore have I ever had them just fall out like that ??

You didn't have the cylinders honed? Or check clearance?

. i wish that i had scene this before i rebuilt mine lol I was told that there is an upside right for the ring, what is the easiest why to determined it position? At 944 you mention to line up pin /ring so that is doesn't get in the wrong spot I'm not sure what we are talking about. Witch pin are we watching for where dose the gap sit on the ring thanks lost a little bit would you mind explaining thanks. Funny part is I made the y pipe mistake and it was a night-mare.

what kind of lube are you using?

My 1000 SDI Rotax locked-up on me last winter. Does anyone think it could only be a seized piston, or is it the nightmare scenario I'm hoping it's not, ( crankshaft bearings ) ? I'm gonna' start to dig into it in the next week or so. Any suggestions?

Should i use a oem pistons for more reliability or spx does the same?

I am doing a top end on a 2005 rev 600 renegade Sri ho and had to get a new cylinder for one side....I am currently putting everything back together and am bolting the head and am having issues with the bolts being to long and bottoming out on 3 holes of the new cylinder....do you think the refurbished cylinder may not have been drilled and tapped properly after reconditioned....just wondering if you have ever come across this issue?

Its been a while, but do you want to 'seat' your gasket as well? with a little oil? please advise

that a bad rod bearing how many times did u use it. i changed a lot of piston and never had a bearing come out like that that had a lot of miles on it

Would my 02 MXZ X 800 have non caged needle bearings as well? Gotta do a piston and jug on it and would appreciate the knowledge. Cheers!

where did you buy your royal purple assembly lube?? i cant get any at my local powersports shop or online! any options????

should have u not honed it to seat the rings beter ??

my sled has 7000 miles starting to lose compression would you just do top or complete rebuild

Do you know of whereabouts I can purchase a piston for a 1968 Evinrude ' Sail Master ' ??

Seriously, have you ever done a rebuild on the trail?

How do the SPI pistons hold up

In the backcountry, sled won’t start, lemme just swap my pistons REAL QUICK

how would u change a piston on the trail?

orgs parts is about a 5 minute drive from my house

theres that screw driver lol

What, you dont hone your cilinders?

did you have to set the ring gap on the rings or do they come pre gapped?

Im going to work on a ultra so i was wondering how much this costs

hahah excuse me i ment make no male :p

These engines really need to be designed better, particularly the Rotax. Seriously, a rebuild required every 300 hours? Humanity as a whole is pretty sick and tired of having to rebuild engines. Somebody needs to design an engine that will run for god damn forever and never break. If it requires titanium in it to build it, use titanium. If it requires aluminum, use aluminum. If it requires vanadium steel, use effing vandium steel. Whatever engineering and metulurgy it takes to make an engine you never have to fuck with every again. You can't tell me in 500 years of designing and building engines, humanity still can't build one that is worth a fuuuckkk for reliability. I can't speak for everybody, but I don't enjoy working on engines at all. I'd rather go to the dentist to get two root canals. I do it because I have to, because of piss poor engineering. The worse thing is I am usually not the orginal person making the buying decisions on this crap, I just end up with this kind of things used and second hand. So I have no input on deciding what engineering to support with my dollars or not. You folks need to demand more from your manufactuers, and stop buying stuff that has crap under the hood.
