Hi!
just bought c force 450
and i have couple of question, hope you guys can solve them 

mine is electronically limited to 40 km/h but i hope that i can find solution for that (post that later)

first of all, first variator(clutch), is this same kind like scooters have? if so is there limiter also?
and where you can buy different kind of weights?

second, i read somewhere that throttlebody has limiter, is it easy to remowe?

and third, which miles/km you do have to chance timing chain? (mine has now 20 000 km)
and what about engine oil? this thing have not wet clutch i believe cause it have first(clutch) and second variator.

and here comes question number four. anybody put serviceable and adjustable shocks like fox, walker evans etc. I believe 800 cc model have some kind of serviceable shocks, do they fit this one... dont know..

and if somebody can put servicemanual (which is find in this forum) so i can download it, google says something about error when i try to open page..

Thanks a lot 

You have no clutch. The primary uses the belt as clutch. when you idle the primary let go of the belt untill you accelerate and it starts to grip the belt again. so no wet clutch.   what i know abou the timng chain is that in desen't need to be changed as long as its not damaged or to loose.   

Om my 520 i have changed the front shocks to bronco. Haven't changed the m at rear yet but sooner or later i will do that to.

The speed limiter is in the ecu and needs tpo be reprogrammed by a dealer. (on some models you can disconect a cable near the ecu. On models made 2016)  There sholden't be any limiter by the trottle or the cvt. It's only electric limitet to 40km/h and not horsepower limited.

Herenis a manual.  (some things can be different from the manual depending on model and registrations) http://atvtillbehor.se/C%20FORCE%20450%20SERVICE%20MANUAL%20(1).pdf
