    yes. i used the feeler gauge i got and adjusted them. i will re adjust them sunday because tomorrow i will be out of town. but ill double check that and the timing marks to make sure they are lined up .

    no i dont think its some gigantic bore now. its just a little bit higher compression than stock too. ill see about the auto decompression because for some reason the little tab by the kick started doesnt move when you kick start it. it started perfect about 2 weeks ago without the decompression..but since the timing advance thing decided to come odd while riding it hasnt ran..everything is put back together right.

    the auto decompression doesnt work at all..the little thing that moves with the kick started doesnt work.. i could do a manual but i dont have the right cables or mounts..does anyone make an aftermarket manual decompression for it?

    thats the thing with older xr's..they fire everytime the piston goes up. you can either install the cam lobes up or down stating the manual..it fires like a 2-stroke but is a 4-stroke. so theres really no wrong way to put the cam in..i have all the timing marks lined up. and i know its getting spark. pretty sure its getting gas..the kickback friggin hurts sometimes..like real bad. i might try a lil bigger main jet. the carb was stock. should i have touched the air screw??i have a better filter..bigger pipe..higher compression piston..should i be running a certain kind of gas with a higher compression piston? and its bored .040 over

    alright..heres an update...i found out that it might need a new countershaft bearing in the right hand crankcase..i think this only beacuse in the manual it says if you experience kickback..which i am. it needs a new countershaft bearing. the thing is i cant find the instructions to get it out and install a new one..is it hard, do i need special tools? also. could this cause a bike not to star???

    alright...update..i took the right side cover off..and there was something hanging there..it had unscrewed itself. i don know the name of the part but i put it back on right and tightened it. re-did the timing chain. as in realigned it with the timing mark. cleaned the carb. and still wont start..its getting spark and fule..when i pulled the spark plug it was black..which led me to believe that the bike was in fact NOT running lean or else it would be white..so idk whats wrong with it

    http://www.thumpertalk.com/forum/showthread.php?t=500969 go to this post. and answer here if you have an answer.. Thanks If you dont feel like going theres heres the short story. got a 1982 honda XR250R..had it rebored .040 over with a higher compression wiseco piston. it has an opened up exhaust, and an opened up airbox. so i got it all together..timed it and everything..wouldnt start..i still had the stock 125 main in the carb. so i got a 130 as suggested by someone on here and it started.. ran for a lil while then made a loud pop and shut off. ..would not start back up. and backfires if i try to start it. could it be that i still have it too lean? or what could cause it? Thanks

    at the end of my wits.
