If you go to the pinned stickies above (find the ones where Grayracer513 has them marked "Read These First"), you'll eventually find mention of the o-ring mod, for the accelerator pump.

See William1's pinned sticky in the WR Forum about "Eliminating The Dreaded Bog"...... There's some pretty good info on accelerator pump operation, & timing & such in that thread.

Getting your jetting dialed in, or rather, swapping jets if needed, now would be a little easier while ya have the carb off. :thumbsup:

Or, you could send it to Zip-Ty, and have them do their stuff to it.....

Be careful using WR info for a YZF. The carbs are somewhat different in how they are set up.

In most cases, the carb on an '08 needs nothing other than proper jetting and tuning.
