That must be why my VOES is grounded when she's idling. I couldn't believe the amount of vacuum sucking through those hoses..........

 

As recommended check all wires thoroughly going to ignition pickup. Also verify all grounds are nice and clean.

 

Hey, did you ever find out what was causing your miss under a load. I have the same bike and same problem. I changed the ign switch plugs wires coil battery and still having the same problem. Would love to find this one...can't ride it like this.

 

You are better off starting your own thread........

 

Since my post here almost a year and a half I can tell you that when I put on a new S&S Shorty Super E this summer it took care of my issues of hesitation and ruff running under load, and gave my ride more performance than it ever had.

Junk the Keihin butterfly carb and you will be amazed at the performance too.

May not be the answer for everyone. Do the basic tests to make sure it's not something simple and inexpensive first! I had rebuilt my carb and even put in an Anderson accelerator pump kit, and I'm sorry I wasted so many hours, days, weeks, and years running that crappy old carb and trying to make it work!!!

 

Yeah, Johnny, I told you that you would like that S&S. Makes a world of difference over the stock POS Keihin.

 

The description sounds just like a fuel issue. I am cleaning tank liner out of my left tank. I had bit of liner make it into the carb and it clogged the main jet. Bike idled fine and it could go unless I tried to accelerate with any power all I would get was spitting and sputtering.

Pull the carb, disassemble and clean with copious amounts of carb cleaner (I like B-12).
