new belt slow take off...

[superscoot]

so i installed a new belt top end is great
but its so slow at take off any idears? now i noticed ive got a 2000rpm contra spring on so im guessing thats to stiff for the new belt and causing slow take off?

[wordslinger]

..could be that you need stiffer clutch springs...

[streido]

Sounds like the new belt may be slightly longer to me. The 2000 contra should help take off if anything tho it may be too stiff to get to top speed, at least it was on my A50. Think theyre too stiff for a 50cc 4t, 1500 seems to be the stiffest that works on them.

pulled the clutch off again and i have 2000rpm contra and clutch lol who ever had the scoot before me god knows what there set up was

so gonna get them changed around see what works the best or do you think as its a new belt also wider could that be the problem? might need bedding in so to say... mind you i couldnt moan about the top end doing 52mph verified via gps better than 45 mph lol

streido the new belt is a bugger to get on but once on all is fine...ill let the f**ker bed in ride around on it for a couple hundered miles

[streido]

The belts do take a few miles to bed in usually, at least mine always feel as if they do, after 50-100km or so mine feel ok.

The 2000 clutch springs may be ok to use, what scoot do you have?

It does sound like your new belt is longer if you gained 7mph on it. I used to run a 736mm belt when stock was 729mm, that gave me similair gains to what you got, thats why i think it may be a little longer on yours.

ive got a 04 super 9 ac well im gonna get me another belt as well..( always good to have a spare laying around just incase) and put that on to see how it goes only if the new belt dont show any improvement over time

How much wider is the new belt? For proper fit it Must sit at or equal to the top of the rear pulleys, and Tight on the drive boss. Any other fit is wrong. I believe trading the spring will fix it tho...

[superscoot]

oh gawd..there is a noticeable diffrence im also gonna change the contra spring out for a 1500 i dont mind a bit of trial and error to get things right

[wordslinger]

..trial and error...tuning...is the key to success...


..just today, i've had my clutch completely disassembled 4 times...changed the drive belt, swapped torque drivers, and installed 5gram sliders in blace of 5.7....


..and it's better than when i started...

Start taking the yellow ones when that urge hits you. They work.

I stole a gum ball machine from the Shriner's Club, and keep it full of the yellow ones next to my desk.

That's the Blue ones...
