87-89 TRX250r cylinder sleeve in 85 ATC 250r cylinder, will it work?

[Ryah]

I just picked up a sleeve for my 85 atc250r that is for an 87 - 88 trx250r. Will this sleeve work in the 85 cylinder? I know it has the intake bridged, but this is not an all out race machine, so the bridges should help with keeping the piston skirt from cracking, correct? I guess the main question is will the ports and intake and exhaust line up correctly when it's put in the 85 cylinder or should I just wait for a good buy on the correct sleeve?

I believe the 87-89 will work as long as you use an 87-89 trx piston. If you get an 85-86, then you can use the stock oem piston.

I think this is a bad idea with cylinders so easy to find. You could get another cylinder and have it bored for what you'll have in your cylinder.
