Has any one cut down the stop on a US 2000 WR and if so how much to cut and what is the original length and the desired finished length. I am pretty sure I need mine cut as my throttle only turns about a quarter or so, and my friend smoked me on my xr600, last time he rides my 600, he'll have to learn to hold his own on the 85 xr350. Note I have read the instructions for the 98-99 models but want to make sure of the procedure as Dirt Rider May 2000 says to grind 16mm off the stop but doesnt say what length for the final product.

Baja Designs and others on this site have found that using the YZ426 throttle stop is the correct action for the y2k WR400. If you want to shave down your stock stop, call Baja Designs www.bajadesigns.com and they'll set you straight on the length.

Ok, don't quote me, but I believe the total length should be 1.05" (26.67mm) for the '00. I cut mine down to a hair under this amount and don't notice anything strange at WFO.

See the archives for the discussion or just make it easy and order the YZ426 stop.

The 98-99 lenghts are invalid for the '00

I removed my throttle stop completely on my 2000 wr and have had no problems

When I picked up my '00 WR my dealer told me
to cut the stop so that the finished length
was 8.5mm not including the head of the bolt.
Guess I'll find out this weekend whether he
was right.

Tried out the 8.5mm throttle stop this past
weekend. Works great! I measured the piece
I cut off and its almost 16mm exactly.

How big of a diff does the correct stop make?
I raced my own xr600 with K&N and supertrapp and it pulled the wr easily.

Lets put it this way. The throttle stop is around half the size after you cut it down. And that's about how much it limits your throttle in stock form! The throttle turns much further!!!!

I couldn't get at mine in place so I had to rotate the carb. I couldn't get the stupid rear intake loose so I took the subframe off and rotated the carb-airbox and all. Yeah, it sounds like a lot of work but I had to up the spring preload anyway and thats the only way I could get at the shock.

Do any of you get the feeling that the people that designed this bike don't work on their own bikes?
