Hi i am form england and have an aprilia sr 172, wich is the engine with the nut on out side of the casing. I am having problems getting the most out of my bike i think my rollers may be too light but i coloured variator with pen and it wore away all of the ink so it was showing me the belt was rising to the top, how ever it only goes 80mph
here is my set up:
ported malossi 172 kit
pm tuning exhaust
26 phbl dellorto carb
polini variator using 11.5gr rollers
polini belt
pm reed block
and pm tuning race crank
i did have a gear kit and 16gr rollers but i didnt think it was very good accel, i raced my friend with runner 172 and took me untill 60 to over take him, so i took the gear kit out and am currently running 11.5 gr rollers, it seems like its fast, but thats only becasue i think the rollers are too light, and like i say it only does 80mph!
when i had 16gr rollers and gear kit in i dont think it was much slower accel if anything its either slower or the same wich is confusing PLEASE SOME ONE HELP ME!!!!
