Lets see if you can help on this one guys and gals...I've been doing some minor stuff to the YFZ the last few weeks since I bought it, and yesterday was really the first I've had a chance to actually make sure I put things back together correctly, so to speak. Everything starts up right, fluid levels are good, so I got it between the garages (live in an apartment complex) and just basically wanted to make sure I could go through all the gears, even though speed wasn't an option. Success! Next, at a rolling idle with the clutch pulled in first, I tried to drop the hammer a bit and this is where the issue is. I got the bog that these bikes are notorious for, just for a second, then it came out of it and took off. I have stock pipe (not sure if the baffle is removed or not, I'm not sure what I'm looking for), no lid, and no idea what the current jetting is on the bike. I did the zip tie mod last week thinking that if I did have a bog, this would take care of most of it. Nope. Let me know what you guys think.
