86r needs some more speed??

[dirtbike77]

ok i have a 1986 atc250r her are the mods...

fmf pipe(fatty) and fmf silencer
22.11.9 tires in the rear
.60 bore.
mild port job
49 tooth and 14 front sprockets
150 jet
boyessen intake ( 6 pedals)
run r-50 @32.1

the bike runs like a bat out of hell, i had the fastest bike in my nieghborhood for a while. now this past weekened i got beat by a bansheee with a set of fmf pipes and sprocket change? not bad but i got beat.. i was wondering any other mods i could do or try?

Try a 38 or 40 tooth sprocket. You lose some acceleration ( on a 250r it shouldn't matter :D ), but you gain alot a of top end. :twisted:

49 tooth, thats a huge sprocket, I think you mean a 39, I have 14/39 on mine and it hauls, but I have a full port job, cut head, a/s carb and more. I'm using a 182 jet, now its a 330, I haven't figured out jetting yet.
