636 Issues...Bog at 2K RPM

[EnticeMediaWorks]

I've been triding this bike for over a year now and it's ran just fine. I run my idle at 4500RPM's for stunting and as soon as I dig into a little bit of brake the bike bogs at 2000RPM and starts to sputter. Otherwise the bike runs fine under power, it only seems to do this at 2000....

It only does this when it's hot, It seems to start at 212 degrees. Otherwise the motor seems to pull fine before it gets that hot. We drained the coolant thinking head gasket, but the engine ice was fine, no oil.

We've tested compression, leak down, coils, valve clearance, throttle body sync, new plugs, bypassed the powe commander, and numerous other things im forgetting and we can't figure it out. The problem continues...

Anyone have any ideas????

My 06 600rr has the exact same problem, and i've checked most of the things youve checked too, im starting to think wiring harness or ECU

hahaha no Honda stickers that I've seen on there. Gonna wrench on it again after dinner and see what I can figure out...

the tps is adjustable ..

not saying thats it but probably worth checking and i know this is gonna sound strange but i have seen rectifiers cause a similar problem, the real strange part is they were still charging the battery but for some reason would make the bike run shitty ..

HMMMMMM.....This would make a lot of sense... I think I may have killed my rectifier.....I'm gonna go check that.

I know this is a couple years old but did you figure out the problem?
