Top end power

[cbittner72]

I’ve got a 96 200 with stock muffler and FMF woods pipe. I’ve put 240 miles now on this new to me bike. Went all through jetting and it’s running really nice. It has tons of low-mid power, almost can’t stall it, wheelies no problem. But, when I hear the main power valve open it’s mostly just noise, there doesn’t seem any power increase. So my question is if this is the characteristic of that woods pipe and I should consider the desert pipe, or to consider looking at a top end, power valve cleaning? The prior owner had rebuilt both with a total of 440 miles now.

Clean the power valve thoroughly then try it again. You have the correct pipe for a 200. If that doesn’t work come back here. For that matter, come back here anyway!

Check the power valve.

Some run the Desert pipe.

Thanks! On the to do list now. Will revert eventually

Do you know how to check the power valve without taking it apart? If not search on youtube for KDX power valve test. Theres a short (maybe 2 minutes) video showing one in working order.

I finally got around to removing the small round cover to check pv. It’s working and I think I was just feeling the end of 2nd gear and needed to shift... when the pv valve opens in third I can feel much more pull. Eventually I’ll clean the valves, probably when I hit 100 hrs. Thanks

Following up for others. I finally did a top end on this bike and when I disassembled the kips, I found the washers 11009-1344 that are supposed to be on the spring-ball bearing assembly bolt were inside on the main kips rod instead of on the bolt. This made the kips response sluggish because the ball was forced into the gear 16085-1274, and I could see a score on the kips gear surface. The kips is working much better now and opening quickly.

More "previous owner" magic! Congratulations on getting it sorted.
