1981 GS450Tx been running and idling beautifully the last 2-3,000 miles until last night....
I accidentally ran the GS completely out of gas yesterday. I have of course been on reserve before, this time I ran it out of the reserve too. I managed to limp it along a little further by putting it on Prime and filling the float bowls as much as possible. I filled it up, rode on to work and thought I was fine. On the way home I was on the highway going about 70 mph uphill and it started to dog badly. I limped to the side and sputtered along on the shoulder to the next exit. I could start it, but any time I try to accelerate it bogs badly. I rode the 3 miles home, but it felt like it was running on only one cylinder most of the time.
I determined the problem is with the right cylinder (as you sit on the bike) because if you pull the left plug wire it will barely run and if you open the throttle it dies. In contrast pull the right wire it'll idle and accelerate better than you would expect running on one cylinder.
My suspicion is that I sucked something up into the right carb from the bottom of the tank, but before I pull the carbs I wanted to be sure there wasn't anything else I should be checking.
Any advice/guidance would be appreciated!
Best,
Parker
