Hey all! Would love some help trying to diagnose what caused my 1100 to stop running last month. Got it back to the garage and haven't had time to dig into it until now.
History: Replaced fuel pump after the OEM pump demonstrated the dreaded "seizing when hot" symptoms a few times over the last couple of years. Replaced with the Airtex unit that goes into the tank and it operated without any issue whatsoever all summer in all conditions. The vacuum valve was bypassed before the pump replacement when I was trouble shooting the OEM pump failure and the vacuum line is plugged with a golf tee. No other relevant history comes to mind to mention...but please ask if it helps point us towards a diagnosis.
What happened: Had been commuting on the bike all week when all of a sudden within a few blocks the motor goes from running fine to running at what felt like partial power. Similar to what would happen when the OEM fuel pump would heat up, but in this case I had a) the replacement pump that had been working fine, b) well over a 1/2 tank of gas and c) the temps were very reasonable (low 80s).
As I noticed the motor power decrease, I was able to pull out of traffic as the motor quit. I was able to get the engine restarted, but only after giving it some choke. Once running I could remove the choke, but any application of throttle would kill the engine. I needed to move it a few blocks to a safe place to park it for awhile, and I was able to do so by keeping the choke on and sparingly applying throttle. Eventually, she wouldn't start at all.
Now that it is back in my garage and she still won't start:
- I can hear the fuel pump when I turn the key on
- I haven't changed the plugs since I've owned it - bought it with 22,000 on it and it now has close to 50,000. So I've purchased a set of Iridium plugs but haven't put them in yet.
- Checked the air filter that I installed earlier this year and it looks fine
- Pulled the battery and put it on a trickle charger since I've run it down a bit with a few starting attempts.
Anyone want to help point me towards where to go next? Better yet, anyone here locally in Indy want to come over and play "fix the bike?"
Would especially appreciate that if we start digging into the carbs to check them...that is one place I haven't gone yet on this (or any) bike.
