Hey guys and gals! Picked up a 04' KFX 400 and wondering what a good sprocket setup would be for trails? And another setup for road routes? Looking for good bottom end w/decent top for trails and more so top for routes. Thanks in advance!

I have read with some aftermarket clutch kits you don't reuse the judder spring and to read the instruction to see if you use it or not. The Alba/Artrax kit comes without instructions and their closed on Sat & Sunday. So I'm looking for help if anyone knows the answer. This is for an 07 Suzuki...

So I have an 03 z and put on a tusk heavy duty clutch at the beginning of summer of 2020 and I’ve torn through 3 cables within 3 months. I’ve snapped 2. Any ideas of what could be wrong?

Howdy, I have 2 z400's one is an 03 that has K&N intake, FMF quad core 4 full exhaust and has been re-jetted and tuned, other is an 07 with stock motor amd exhaust but upgraded aluminum skid plate, rear grab bar and nerf bars. Just joining to be around like minded people. Happy riding!

Got a KFX 400, was running shitty. Backfiring, wouldn't rev up. Nothing. Well. I went back to stock pipe, switched stock 130 main for a 145 main and I got it to rev up great. Has a high idle but revs up. Header gets red hot and I'm assuming both these are in effects to it running lean. Any...
