Installed 9:8:1 gears yesterday, stiffer contra spring NYC(1000 rpm), lighter rollers, top speed remained unchanged at 50 mph, same as stock gears.
I was expecting hit at least 55. Noticed a lot of low end gone too, going have to re tune the trans.

Re: Flash 9: Sanity Restored
Wheelman-111,
Im running same bore and jet, stock carb, but 9:8:1 gears, I was wondering what contra spring your using?
Also are you still spinning 42g's in the variator?

Re: Advise on building for acceleration
Just using a new OEM belt.
My clutch currently engages around 3000-4000 rpm right now. I'm looking for stiffer springs... Seems like the power band really kicks in over 6000.

Re: Advise on building for acceleration
Ok thanks for the response.... I'm currently running the Malossi white center spring, not sure if it's 1000 or not?
Also running polini 6.9 rollers, I have lighter ones that came with the variator I think they are 5.6.
I'm going to order the gear set.. Any suggestions on a good brand of gears?

Re: YMS V8 pipe on stocK SA50
Well I installed it and it sounds awesome.. Nice throaty tone. However it seemed to lost some low end torque, top speed stayed the same around 44.

Getting a SA50P this weekend advice
Hey guys Im pickup a 2001 Elite 50 this weekend - all original with only 600 miles.
Only problem its been sitting for 5 years in a garage.
I know the carb will need to be cleaned, anything else I should check/replace before attempting to start it?
