Slow pull away By weskusklong (Read 1,304 times)

Hi Guys

Bought a used 150 Jonway Spray 2007,it revs quite high before pulling away and it only goes up to 6000 to 6500 revs when it runs out of breath.

I have three others and they pull away immediatly when throttle is opened.

Any ideas? (wrong belt size maybe !!!)

Need to adjust the roller weights, perhaps the clutch is slipping etc...new belt...all of the above

Last week I found out that my scoot doesn't like the 13gr sliders that I stuck in. I had to put back in the koso 15gr rollers ( purchased from scrappydog in mid march) after taking a short scoot to the store. Please note I have an A9 cam installed aswell but everything else minus the airfilter is stock. With the 13gr sliders in , the engine rpms were much much higher taking off from a stop and at full throttle I was only able to hit about 45mph max . With the 15gr rollers in, my scooter responds better at lower rpm's and takes right off . Topend is improved aswell . My belt is a gates 835 on a longcase 150cc engine.

Welcome to Scooter Doc, weskusklong. I tend to agree with sprocket. Get everything back to stock and new and this will give you a basis for any mods or troubleshooting.

Variator Weights would be a good place to start once your scooter is back to stock Each scooter is different. The setup I have on mine may not work for you. One has to keep at it till its where you want it.
