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.

I tried it on my 04 and it worked but then i did the cammod and put it back to stock cause of others jetting problems i think it was the jd needles. I've got to try it on my 05. Look at the wr jetting on thumpertalk it will give you a good idea where to start.
