Does changing the leak jet correct the Throttle snap bog problem on the 05 FCR (yfz450)? I took a look at the squirt and it seems very weak and lasts 1 sec. I read that by blocking the leak jet on the earlier years with a bb or small ball bearing would work. Has anybody played with the 05's yet.

the leak jet should be adjustable. if you go on thumpertalk there's alot of info about this. the new boyessen accel. pump bowl cover basically masks this problem. if the correct leak jets and spray length are dialed in, you don't need it. check to see that the spray doesn't hit the slide before its out of the way.

whats quicker, your yfz or 400 w/xr motor?
