Stutter or Loss of Power with load or open throttle
Sigh. So I just did a VERY thorough de-winter on my 1100, including a carb clean/rebuild. I took out and bypassed the fuel pump and reduced the length of fuel line. It also has a new filter in-line and a near-full tank of fresh gas. With the new fuel setup and clean carbs and new gas, I rode it twice, for about a half hour each time, after warming up, and it ran beautifully, all through the throttle range.
I then changed the oil, made a little whoops (had energy conserving oil in, but didn't run it, drained and replaced with good oil) that I fixed, and it ran fine on open roads for another 45 minutes.
Tonight, I go to ride it, I take a passenger, and it's bogging under throttle. Stalling a bit easily, so I pull the choke back a bit (more gas) and it gets a tiny bit better, but not really. I think maybe the extra weight is an issue, so after I drop off my passenger, I take it out alone, and same problem. When I open the throttle (clutch engaged or not) it has a 50/50 chance of bogging and acting like it's stalling, or of revving just fine. With a load on the engine, it'll power up a bit and then bog back down. I have a clear fuel filter, and it's full of fuel, so I don't THINK it's fuel starvation, although I could try and fill the tank more, but even on reserve it did it. I'd say I screwed up my carbs, but why would it run without issue for so long before this?
I'm at a bit of a loss, I was VERY thorough with the carbs, and the fuel and air filters shouldn't be problematic. Suggestions?
