Yamaha 1100 HELP !

[BH]

Just got this bike. Its been running great. Yesterday I had to switch over to reserve fuel, filled up at the next station, started fine this morning but after work it wouldnt crank up.
I always full throttle briefly but I wasnt getting any rev and it petered out. Spent 2 hrs messing with it but nuthin. I had to leave it at work.
Any suggestions would be very appreciated because its got to be out tomorrow plus snow is coming.
HELP ?
Thanks in advance.

Hopefully you didn't get a load of real bad gas or a bunch of goo and junk from it being on reserve is in the carbs. Might have to drain the tank and carbs and replace with different gas. I would try that first after you see if you are getting spark and so on.

You said you just recently bought this bike? After you filled up did you remember to switch back to your primary tank?:confused:
