My new to me 86 GL1200 is still not running right. I bought it 200mi ago. The first 150 were fine. THen I started to have problems with loss of power. I have limited my rides to within 10 to 20mi of the house, and for good reason. My last postwas diagnosed as a fuel caproblem. When I started to loose power, I stopped, popped of the cap, and then it was fine again for 10+ miles.Monday while on a ride, it did it again.This time, the cap trick did nothing. It ran at 1/2 powerfor another 3-4 mi, then lost all power. I pulled over and made a call home, and about 2-3 min later, it started and I drove home, but still with very low power.
Once home, I checked the fuel pump. It was getting voltage, I pulled the lineto the carbs, but did not pump. If I would remove and remake the power to the pump, I would get 2 or 3 pump cycles, even with the outlput ine line removed, but did not get any flow, other than whatgravity provided out of the tank.
Tongiht, I installed a new pump. The pump runs for 3-4 seconds after the key is turned on until pressure is in the carb side and stops. If you work the throttle, it will cycle on and off. Great I thought, so I went for a ride. I still only have 1/2 power (or less) so I only went 2-3 blocks and came back home.
While the bike was still hot, I wet my finger and touched the exhaust on each cylinder. The two forward cylinders (towards the radiator and front of the bike) sizzled the spit on my finger.The two back cylinders were warm, but not enough to sizzle spit. It starts and runs just fine at idle, and some times when trying to accellerate with full throttle, it will take off like a rocket for 3-4 seconds, and then bogs down again.
So, my question is, what to do next? Do you think it is no spark on the two back cylinders or no gas flowingthrough to the two back carbs?
