The dreaded Bog
Posted March 20, 2005 - 06:02 PM
My bike is jetted right and runs near perfect. No problems starting, fouling plugs or running too lean and whitening the plug tips. It just bogs when I open the throttle too quickly off idle. I was told it was an accelerator pump problem that some of the older (before 2003) bikes have.
Any suggestions on how to fix this???? Mine is a 2002.

Same deal on my 04 WR450, runs clean, runs strong full range from bottom to top end. Just can't open the throttle really fast from off idle. I have a smaller leak jet on order, as suggested by JD. If it works I will post the results.
It will work for you like it did for me and countless other TT members. If you absolutely have to spend $80-$90 to solve a $10 problem then by all means get the new trick pump cover.
ps. My YZ came with a #40LJ. There is no bog. If I snap the throttle open I get a good view of the sky. The #40 I put in the WR250F put an end to my double pump to get moving habit.
