Thanks, VTwin. I'll probably order one. Was looking at that one earlier, but hadn't thought to mount it in the console a you suggested.
Was optimistic in my earlier report. Haven't resolved the misfire and running on one cylinder issue. Now believe three bike is flooding out in the left carb.. Another tear down coming up on Monday. Stuck in FL until late Sunday.

Bad luck. Are you certain it's the left carb? "Driver's" side that is? If it's the right, it could be the petcock causing flooding through the vacumn hose.

radianrider · 06-22-2012, 07:59 PM

Definitely on the left (driver's side.) Gas coming out of the air box, so opened it up and found gas sitting in the throat of that carb boot.

Suspect float needle and/or float is at fault.

radianrider · 06-29-2012, 07:12 PM

Float needle was the problem. Running beautifully again.

Took it out for a ride. Had to bump start it after a stop. Starter destroyed the brushes three weeks after I rebuilt it. Sheesh.

New to me used one on the way from TN thanks to a GSResources forum member. About the same cost as the parts to rebuild the original would have cost.

Eventually, I WILL be able to ride more than an hour before taking on another repair.

Congrats. Mine was loading up on the last ride. Stalling and running badly. Looks like mine have to come off again. Maybe just some bad gas.

Both cylinders? If so, suspect petcock...if one, probably the carb.

Right cylinder was running great. Could pull the sparkplug boot of the left and it made no difference. Pulled the right and it stalled immediately.

Got a used starter and installed it. I think I'll be able to actually RIDE the thing!

Well yeah ...... for a while ........ until something else .........

That's generally the way with any old bike, sure some (mythical?) bikes never seem to have a problem, where's the challenge in that? Have fun riding!

Far too true! I took it out for a short 20 miles today and it ran beautifully. (Well, slight popping on deceleration out of the left cylinder--screw mixture set too lean I would guess.)

Have to admit, I was riding along waiting for something to go wrong.

radianrider · 07-13-2012, 08:14 AM

Took it out yesterday and it ran beautifully for about 40 of 45 minutes. Five minutes from home the left cylinder started loading up again.

Knew immediately that the left float needle was sticking again. Pulled the carbs and installed one given to me by a GR rider in PA. Seems to be running well again. The old needle is permanently out of service.

Figured out why my choke was sticking and resolved that while I had the carbs off as well.

I pulled the Superbike bars off the other day. Just hurt to ride it longer than about 25 minutes. Went back to the MX bars I had installed a year ago. Resolved the neck pain and nerve numbness kicked up by the lower bars. I can also see things in my mirrors--an ongoing issue with the narrower bars. The MX bars don't look as classic, but they feel WAY better. That'll do for now.

So, starter issue resolved, carb flooding issue taken care of, neck pain gone--should be good to go until the neck

vtwin · 07-13-2012, 06:20 PM

Nice. I've yet to pull the carbs again to find out my loading problem.

Bummer. Have you determined whether it is one cylinder or both?

Got mine out for a shakedown ride tonight. I don't think I've had it running better than it did this evening. Makes me nervous.

radianrider · 07-25-2012, 05:32 AM

Bike continues to run well. Figured out an inexpensive way to mount
The GoPro, so videos to come

I'm going to send the carbs to one of our club members that supposed to be a wizard at carbs. Dog knows I'm not too good at it.

They aren't real complicated and there are some really good walk-throughs on thegsresources.com. A GSR member, basscliff, has bunch of tutorials on his page.
