Oh no... it's another bogging thread! As the title says... I've fitted the smallest leak jet Yamaha sell and my 09 WR still has a slight bog right off the bottom. It sent me over the bars last night when I was trying to lift the front over a log! What's the next step? Do I have to shell out a load of money on a Quickshot thing or is there any more tuning I can do to the stock setup? Will adjusting the needle clip make any difference. The AP timing seems good, the fuel squirt doesn't hit the slide at all. I've not timed the squirt with the #35 jet but with the #40 it was around .5 sec.
