I am about to drop the sleeve in my SXR. I am concerned because the OD of the sleeve is smaller than the OEM one. I forgot if I am supposed to leave some metal from my old stock sleeve in there...

I know that I am supposed to bore it to be .003 to .004 too small for the sleeve, bake the cyllinder at 475 for 45 minutes, put some 1211 around the top and drop it.

I would reccommend that you have somebody with experience do this kind of stuff (not questioning your mechanical abilities here!) like an experienced machinist. I know that there are certain steps involved when doing this like applying certain amount of pressure on top of the sleeve during cool down. maybe paul would like to chime in here!:sneaky:

My brother has dropped a lot of sleeves into Sea-Doo cyllinders. He is doing that part and I have an excellent machinist that does all my boring.

The only concern I have is whether I should have lefter over metal in there from the stock cyllinder. It is just a Kawi specific question.... I want to make sure I have the correct sleeve before I bore.

thanks Steve. :biggrin:

I'm not sure if I'm understanding your question correctly, but here goes.

I would not leave any old mterial in the casting, unless it's a typical , Kawai stepped sleeve, which doesn't give you much choice but to leave the stepped portion intact.
If the new sleeve is smaller than the oem, I would not use the sleeve until you contact the manufacturer back. to make sure they don't have an issue with that particular sleeve??
When the cyl is at operating temp, there is a degree of movement, any additional material left will "work" in the casting & possibly cause a issue down the road......... I personally would try to avoid that.

ski ya, Paul

It sounds like you have one of those funky repair sleeves for the Kawi 750,if that is the case you bore out the old sleeve to accept the new sleeve and I am unsure on the clearance because it is steel on steel instead of steel on aluminum.

Correct sleeves

I have good replacement sleeves in stock for the SXR-800. They can be dropped into 750 cylinders also, but will reqire "match porting" in the 750 cylinders. $110.00 each.

My sleeve was cracked from a crank bearing flying around my motor like a pinball machine smashing everything in it's path. :skull2:


I got the sleeve on Ebay. It is a LA Sleeve for a Kawi 800. The boring is being done today and I am dropping the sleeve on Friday.

Here is the recipe my brother is using:

1. Bore Cyllinder .003 to .004 too small for sleeve
2. Bake Cyllinder at 425 degrees for 45 minutes
3. Wipe 1211 around the top of the Cyllinder.
4. Drop sleeve making sure it is exactly where you want it.
5. Cool
6. Bore to size
7. Clean up any porting issues.
8. Assemble Engine.

:cheer:Any other hints would be appreciated. :cheer:

Dropped that f'r tonite. It went all the way in no problem, but the ports are a tiny tiny bit off... I missed by about 1 to 2 degrees. I heated the F out of that thing trying to turn it but it wouldn't move. It is in there.

I don't think the ports being off a tiny bit should make THAT much of a difference. What do you guys think? Stock Superjets have the ports a lot further off than mine.

Anyway...the cyllinder gets re-bored on Tuesday. I screwed up part 4 a little bit, but it is hard to hold that sleeve exactly where you want it.

Bump.... Anyone know how bad this off porting is gonna effect my ski. Maybe 1/14th of the exhaust port is covered. The problem is that it is only on one cyllinder. The other one matches up perfectly.

I just don't want to blow any more motors. :banghead::banghead:

I don't care if I lose a little power.
