Hi All,

I have look at the various post on the tyre upgrade & secondary clutch changes from standard B1 to C1 ,  can I ask what the implications are on not doing the secondary clutch change.

I am going to 26 inch setup

Thanks In advanced

I have a 400s with stock clutch setup and 26" SunF Warriors. I planned on doing the necessary primary/secondary modifications but never got around to it and I've never been completely satisfied with my clutch's performance.
I posted the link to my old thread above. There are a few users who are knowledgeable who gave some useful advice. Apparently these clutches are pretty simple to work on.
Good luck

These 2 videos should show you what you need to know to clock your secondary.

On my 520s /500s i clocked it to B2 and i can crawl slower without the belt slipping and it feels like its uses the power a bit better so i can recomend clocking the secondary.
I now use 28" cst wildthangs on it and so far i haven't had a problem with belt slippage. For the 28" i can clock it a bit more but for like 262 i think it's about right. Sure you can clock it more but your machine vill rev more.
