okay, i de restricted the variator this morning and added a de-restricted Leo Vince ZX pipe. (my bike is a '10 plate Aerox R) For some reason, the 0 - 30mph acceleration is extremely slow... its almost like it's a dead spot for some reason. Then, when the revs start getting higher, the bike seems to kick in and suddenly shoot off.

Does anybody know what could be causing this? i have 4.2g rollers in, everything else on my bike is standard. i didnt add the clutch springs that came with the exhaust... and my carb is not up-jetted,

PLEASE HELP!

how do i get a smooth, constant acceleration?

Sounds like the changes you've made have meant that the transmission is now not matched to the engine. The engine will bog down until it reaches the correct RPM to accelerate (IE the engines power band).

I'd suggest working out a way of making the clutch engage at a higher engine RPM.

Change the springs as this will allow the bike to rev higher prior to the clutch engaging fully, I would change the springs and leave the standard exhaust on the bike and see how it runs first, then you will have something to compare with when you change the exhaust system. You will probably need to increase your jetting to suit the new exhaust system so keep an eye on your plug colour and dont let the bike run weak.

Dont exhausts for scooters sometimes come with a different weight of rollers? Question
