I took my bike into the shop a couple weeks ago, got the carbs synch'd, then changed the oil and went out for a nice ride. I noticed that when i was cruising in top gear and pulling about 5500-6000 RPM's the bike would hesitate when giving it gas. If i ducked down on the tank it got worse, would lurch when trying to keep a steady speed. If I was in a lower gear the problem didn't occur. If I stayed in 6th and got past 6000 it was smooth.
I pulled the tank off last night to see if there was anything obviously not right and check the plugs.
One thing i noticed, there are two rubber hoses on the airbox side of the carbs, one connects to the petcock, and the other was dangling loose, but the end was expanded as though it was connected to something at some time.
EDIT: I also noticed a hose on the engine side of the carbs, what should that be connected to?
Also got a pic of the spark plug, it has about 2000 miles on it
Suggestions on what could be going on?
And for anyone interested there was some Mutal of Omaha stuff going on right next to me while i was dissasembling the bike
Edit2:
I just went and looked around some more and pulled some plastics off and found another hose! From the look and bend of this one it should be connected to the drain in the center of the tank. So now I'm left wondering where do all the rest of these hoses go?!
I have two hoses on the airbox side of the carbs between carbs 1 and 2 and another between 3 and 4. There is also a hose on the engine side of carb 4 (left) the connector where this is connected is plugged on all the other carbs.
here's a pic of what i'm looking at. Thanks again for all your help, the Kat's going on the dyno tomorrow so hopefully this can all get sorted out before then.
TIA
