Hi I bought a STAGE6 variator kit thinking it would improve my top speed and acceleration but when I got it all on and went on my first ride on it and it was going at 40mph and it was revving quite highly a lot higher than before at that speed with the stock variator on it, could someone explain why this is??? BTW I have a CPI Oliver city with an upgraded carb with a 65 main jet, carbon fibre reeds and a 70cc big bore kit.
maybe to low on the roller weights ( depending what you have put in) , or could be your hitting the max on the gearing ratio ( normally you would add a secondary gear up kit in the rear drive to get more legs and higher top speed with a 70 kit )
If you still have the stock pipe ,its going to be holding you back some what . stock pipes are low down rpm , sport pipes are more mid range /high range rpm, they tend to produce the power at around 7-9000rpm.
i own a Sym jet frankenstien , its a eurox with a lot of sym jet basix parts fitted. has stock clutch and variator, uprated cdi ( unlimited rpm) , naraku 6g and 8g rollers fitted, naraku belt, and a leo vince TT sports exhaust. its just a derestricted scooter but pushes well once the pipes power area comes in, on the sym clock 50mph but reality its about 45-47mph. leo vince ( ZX -TT ) has not been to bad, but i have heard that the technigas are rubbish, theres also Hebo exhausts , gianelli and if you able to afford them Yasuni ( they rated very good so i have heard but are expensive )
try a gram heavier, it will drop the revs off for sure, might be enough, might be too much, might not be enough. roller packs are pretty cheap, theres usually 5 sets of really cheap different weight in diff colours you ccan use for setup then replace with what you settle on. theres a general guide on transmission/rollers in the guides section, have a read, get a few sets and get playing. basic tool set, a variator locking tool, jets, rollers..essentials if you own a scooter and want to play with the engine
