I do know they're generally only useful for the variator on its own. I asked my mate he said there 5/6 gram.
another question, will i need to change the clutch bell if i upgrade the cluch springs or replace the clutch completely?
did you get the variator installed? i have an nrg too and having the polini speed control kit put on next weekend.
many people including me dont know much so we dont know how to fix a lot of stuff... thats why answers dont come up easily... anyways i have putted the malossi multivar 2000 on my nrg and i think its quite beast but i need to replace my rollers and stuff since i did it 50cc again and it doesnt go any fast at all!!
Havent had the funds yet, when i do though, itll be on its way will you let us know what difference it makes? would be much apreciated.
definatly get a polini variator and hard torque spring makes all the difference and there is a plastic fan on the front of the variator take that off and chuck it away
