After months of marveling at what a great running bike I have, all the while reading about problems others are having and thinking I'm glad I'm not dealing with that, now my bike has a problem. At idle, she's only getting fuel to the rear cylinder. Last time out, she ran perfectly. About five miles from home I had to go to reserve. No problem, came home and put her in the garage. Haven't ridden for about ten days, fired her up today to run some errands. I noticed she didn't start as quickly as usual but didn't think much of it. She shut down at the first stop and every stop thereafter. Topped off with fuel and came back home. Gave her time to cool down and started investigating. Stator voltage good, about 14.5 volts at 4k rpm. Strong spark on front cylinder at idle, but the front pipe is much cooler than the rear so I'm convinced its a fuel problem. Plan to try Wolfie's back blow procedure to see if it helps. Any suggestions are appreciated.
