hey all just on my way back home from West Yellowstone. Rode 3 hard days. On the second day I started having this bog. It would only happen from time to time and as soon as I give it the nuts it would snap out of it and wouldn't do it for ahwile. Then all of a sudden it would start doing it again.

Well Yesterday morning when I first started it up it didn't do it for about a half hour. Then it started doing it again. I changed plugs and that helped for a couple hours. I noticed it started doing it again after I held it pinned for some time when I was drag racing someone. If I go from a stop to Wot it will not do it. Also if I shut the sled and let it sit for a few minutes, when I start it and drive if i don't go over it seems like 6800 RPMs it doesn't do it. It seems to be doing it after I hold it at WOT or close to.

My clutching seemed to be right on for where I was. I was thinking power valvues but am not sure where to start looking????

Fuel filter needs changing or the TPS needs to be adjusted.

Sticky pump

Mine did it only when it got good and warm. the oil pump would stick once and a while. not the cable just the pump. Sticky exhaust valves might make it bog too.

My 900 did something similar to this, same RPM etc. I cleaned the exhaust valves and by-passed the exhaust valve solenoid.

Well took PV out and cleaned them. I'm starting to think this is not my issue because they didn't seem to be that dirty. There was some pretty sticky crap on it but not much.

Would the TPS cause this?

I'm still having problems with this. If the oil cable was set wrong would it cause this?

this may be stupid but I think i have the oiler set wrong. Is the oiler level suppose to be set so it springs all the way back to where it completly stops?

WTF.

umm no..the pump lever should be adjusted basically in the middle of its rotation, there are lines engraved in the arm, and on the pump housing that should be lined up...

Ha, I bet that could be my problem. To come to think of it after i put on my new throttle cable is when this problem started. I honestly don't think my pump arm has a notch on it tho. Would anyone have a picture to how it's suppose to look set correctly?

this isnt the best pic, but the only one i have of an oil pump. the marks that are in RED are the ones i am referring too..exact location of them, and they should be lined up to make a straight line across...

Nice!!! I bet this is my problem. I know it's not set like that. Will have to take that lever off and clean it and see if I can find a mark.
