So I've been trying to get rid of the infamous bog and just can't shake it. I have the JD jet kit, the bike totally rips everywhere, pulls like a freight train, its just that quick snap of the throttle when you want to loft the front tire up over an obstacle in the low rpms, it falls on its face. After doing the O-ring, setting up the AP timing screw to just miss the slide, installing a #45 leak jet, I still have the bog. I even went for ride after ride messing with the AP timing screw and slowly turning it different directions all throughout the spectrum and the bog doesn't go away. So after hearing a lot of good things on the R&D products, I decided to get the new and improved R&D Power Pump 2 with the adjustable leak jet located on the left side, and a heavy duty linkage spring along with the block off screw for the leak jet in the bowl. I hope this will cure my bog! Funny thing is, I completely got rid of the bog on my YFZ450 with a #35 leak jet and a Boyesen Quickshot 2, and Zip-tying the linkage. But I decided to go a different route this time, instead of continually removing the bowl to try different leak jets. Once I get this all installed I will give some feedback on it, I sure hope it works!
