Hello all,
Rebuilding my 94 KDX 200 R model , Working on the KIPS , found out the main exhaust valve , the teeth are worn , sometimes open and sometimes won't . the side valves work great , As it takes 2 months to get parts where I'm at ,how much power would I lose if the valve is closed ? Or should I take it out until the new part arrives ? Any ideas would be great
Thanks

you'll loose a bit on top if it's closed, and a bit on bottom if it's removed or stuck open.

I'm surprised, usually the center valve lasts forever and the sub valves get shredded regularly. I've replaced the subvalves in my 89 3 times now, but the main valve is still perfect.
