Hi, This is my first time posting and am not sure if this is the right forum so please let me know. I bought an 86 250r that was in bad shape so I went through it. When rebuilding the top end I found it had the cylinder to an 87 TRX so the piston wouldn't fit. Got the right one, boyesen reeds, carb rebuild, etc. Anyway the bike has never ran right after several trips to the desert and trying different things. After it gets hot it starts missing then won't start. If anyone has a recommendation for a good 250R mechanic that is reasonable priced in the San Diego area I would appreciate it. Thanks much
If you do find a shop, please let us know! Most places won't touch anything of this age. It seems like the only options are expensive engine builders.
