thanks im already running 5 gram rollers and i tried a stiffer torque spring and i wouldn't get any speed

i tried changing the clutch springs but could figure out how

also how do you know if you have it idled right?


..your idle mixture only affects ur scoot...during idle and just off idle into acceleration...if ur scoot will set still...idling...without revving excessively high, or cuttin off, then it's probly ok....about 1.5 - 2.5 ccw rotation of the screw should be close..

..keep in mind that in colder weather, it's gonna idle a bit high till it warms up...it's the auto-choke function taking effect...

..5 gram rollers are pretty close to being optimum...again, it's according to your scoots build...there are a cpl of different "builds" of A50's...i ran 5.5gr for a long time...but i'd prefer 4.5 over my 4.7 gr...that's what imma get next...

..there is a link t the A50 service manual, that i posted in the "general" board...it will explain in detail how to change out ur clutch springs...it's a "must-have" for anyone nthat's going to mod or even just maintain their scoot...

..that wouldn't really affect your top speed...just recovery from slowing down, and some..just after..initial take-off...it'll keep ur belt from slipping excessively...

well i got rid of the spacer in the clutch changed out the stock weights for 5 grams put a better belt on it had the mechanic re adjust the valves

yea i put the stiffer spring in it and at full throttle i could only get to 20mph on flat ground

although that was before i cut the cdi   could that have been the cause? i thought it was odd

...but my biggest increase in performance came after i swapped out the stock variator, for my malossi multivar...i think there may be a difference in either the pitch of the ramp plate, or the degrees of forward angle of the leading roller slots in the moving pulley...but i do know that i gained 7 mph after installing the malossi...

..and, again, i can't stress enough the importance of a correct valve adjustment...

..my dealer told me....over the phone to my face that the gap should be 4 thousandths of an inch...  .004 inch

..while in fact, the correct, service manual specified (tried and true by yours truly) clearance is .04 mm...

..if you gettin 50mph downhill, and all you've done is the bushing and the cdi, then i think you're right on track...yup...lol..

..yeah, the spec is .04mm on the exhaust...but i started adjusting my exhaust to .03

..seems to be a bit more peppy...

..but then, maybe the hundreth of a mm is just my imagination...

im getting a steady 40 mph on flat ground according to the speedo had someone follow me before i cut the cdi and i was getting 37mph on flat ground and 40mph downhill and the speedo would read 70kmph now its reading 80kmph so im guessing im getting 50 downhill

...the speedos are generally 5-15% optimistic....

..sounds like ur doin' ok for an A50....

..the 4Ts ain't gonna run like a 2-stroke....

..it takes longer to get them up to top speed, and recovery takes longer...

..however, the ride is sssmmmoooothhhe....... ;D
