Re-sleeving cylinder

Post  Singletrack Gardener on Thu Oct 04, 2012 6:45 pm

Hey all,
It's that time. I have never had to do this before on any bike I own so I have some questions. Any help, suggestions welcomed.

Is it possible to do it myself?

Once the old sleeve is removed is there anything else I need to do before installing the new sleeve?

I'm thinking I will use this kit: http://www.xrsonly.com/dirt-bike-parts-1/honda-dirt-bike-parts/honda-xr-models/honda-xr650r/xrs-only-piston-kit-honda-xr650r-101mm-102mm-660cc-670cc-includes-cylinder-sleeve

Can't wait to get this done! Very Happy

Well after tearing into my engine. I noticed that I didn't need much more than rings. My cylinder still had cross hatching. Honed the cylinder picked up some rings and a gasket kit and I will be ready to go when I find the time to put her back together.

Uhg... Effort??? Eh... BRP smile Looks good.

I am interested in in this whole re-sleeving thing though. I'll eventually buy a big bore kit and will have to have the new cylinder pressed in. I'll probably take it to a shop so they're liable for boo boos.

Pretty sure it has to be taken to a shop. Unless you have a machine shop at home or a neighbor with one like me.

The cylinder needs to be bored without the sleeve to the larger size to accept the oversize sleeve. Then the sleeve also needs to be matched to the piston as most do not come matched.

It sounded like a fairly pricey option, but if you are due for a re-sleeve anyways, then why not.

I just got lucky this time.

ov/size cyl install

yes its a machine shop job, first they bore your cyl, then machine a step in top to stop the sleeve moving up/down, the cyl is bored not quite the size of the sleeve, the cyl is then heated, the sleeve shrunk with nitrogen, then installed , this give an interference fit[ usually 3thou], then they size the sleeve to your piston and lightly plane cyl top to give a good surface for your gasket, its then a pain to fit your rings as the bevel is very small on the lower side of cyl, wish id just got mine bored & re- nikaskil coated
