Hello all, I just bought a 1986 CR250, the cylinder was sleeved, then bored over from prevous owners. There is ton of slap in the piston, too much for me to feel comfortable with. I would like to put everything back to stock, I am told that I can still get a new cylinder + top end for a 1989 and not much is avail for 1986. So my questions is can a 1989 jug, head, powervalves ect fit on to the 1986? Can anyone offer some advice for this situation?
I raced this bike the past weekend in a vintage moto and fell in love with it, in fact my lap times where only a 5 seconds slower on this than my 08 450! I felt I could out corner most of guys out there, this is an awsome bike! Go Honda!! Smile
thanks for the help,

You can re-sleeve it, and nobody but you will know the difference.

Then while racing it, be on the look out for a stock Cylinder.

Resleeve it is. I am going to race this bike once in a while in the vet class so displacment should not be an issue....and if it is well then heck with them. Can anyone recommend a sleeving place + piston. I want to do this right.

Also to clairify the parts guy thought I was talking about a 99CR250, the cylinder for the 1989 is no longer avail from honda.
thanks again for the help

By far the most reliable bike I've ever owned . I raced it in the desert for two years and never had engine problems. I sold it to a buddy of mine in 1990 he rode it for a couple of years and then he put it in a shed . I think he might still have it I'll check and get back to you.
