Hi Gang,
Went for the "BIG" ride this afternoon on the R65LS. Went to put some gas in the tank $4.03 for non-ethanol premium.
Still getting used to her but everything works very good. Rear brakes good and new floating rotors up front very nice!
Is it unusual for these bikes to run on one cylinder when cold? Maybe it had bad gas in it - don't know - but after a bit of warming up the second cylinder fired up. But surprisingly, you can drive the bike running on one cylinder.
Anyway, really neat to be able to be riding this bike - WOW!

Should not do that if all is well within the Bings.
First, a simple check. Drop the carb float bowl on the offending jug. Confirm the small jet in the bottom of the enrichener reservoir well is open. Just follow the long-ish brass tube protruding downward from the carb body.
If the jet is clear, I would then suspect an issue with the enrichener mechanicals and/or choke cable adjustments.
For even more fun, swap the spark plug leads and see if the problem changes sides.
Woo Hoo. Are we having fun yet? ;)

Monte: how would you "confirm" whether or not the jet is open? Are you running a small wire, checking for obstruction?
It was only running on one cyl when it was cold - maybe the carbs weren't balanced? I have a friend who can help me check that.

Take a single strand of copper wire from lamp cord wire.
This is the rule for cleaning out any of the openings in a carburetor. Compressed air and chemicals is best, though.

Yep. Roger that. A thin, single strand of copper wire will dislodge anything that's clogging the "jet".

Thanks guys.
Did get this sorted out. Rode her to a friends house this afternoon. He said "Kenny, why is your starboard carb tilted so far to the right?"
I told him the fuel hose broke when I brought the bike home and in order to get the new hose through the bottom of the airbox, I had to remove the carb. Apparently, I didn't align it correctly
He balanced the carbs for me but the right head with the stainless threaded flange definitely has an exhaust leak - not major but enough to prevent him for dialing it in as it should be.
I'm gonna ride her around, put some miles on her and replace the head at the end of the summer or when I need to. The "new" head is going to the machine shop tomorrow so it will be ready when I'm ready.
She really runs well - it's really a little nimble machine.
