down on power
Well was running up the interstate with a buddy, riding kinda hard. He pulled away from me so I twisted the throttle. Bike was pulling good, hit 110 mph and the bike coughed and lost power, exhaust had a different tone, bike wanted to stall out if I didnt keep the throttle turned. Slowed down bike ran better on the rest of the ride. On the way home, it didnt want to idle with the clutch pulled in at a stop light. Exhaust did sound kind of different also on the way home. I am clueless on this one. Anyone got any ideas?

Alcohol in today's gas is a very efficient cleaner...it tends to loosen all kinds of crap in you tank that was more than happy to just lay there with "normal gas". Check your petcock screen. Disconnect the gas line from the petcock, run a longer line to a gas can...and either turn on your petcock or apply vacuum and observe gas flow. Unless your bike has been stored improperly, nothing big enough to clog a jet should make it past the screen...YMMV

I just had the carb off a couple of weeks ago and took it apart and cleaned everything. I was running kinda hard last night, I was thinking I probally sucked all the gas out of the bowl faster than I could pump it in. But a clogged petcock screen would slow the gas going to the carb. I will have to check that. I have already sprayed the intake gaskets and around the carb with starting fluid looking for a intake leak. All good there. Thanks for the help everyone I will let you know what I find.

Did you spray around the intake where it goes into the head? Had the same problem with mine and it was the intake gaskets. Was the manifold loose at all?

yes manifold bolts were tight and I sprayed starting fluid around the manifold gaskets everything is good there. I have rode over 500 miles since my problem the other night and the bike hasnt missed a beat. Guess I just cant run 110 mph down the interstate anymore....lol.
