Lazy GL1100

Post by Valkwing »



Ok fellas, brought home a slightly running 1100 this fall and am starting to go through it. Rebuilt carbs completely, reinstalled, and synced. Started up immediately with no leaks:) So far so good. It idles flawlessly once warmed up, or on choke after a little bit. However, it's extremely lazy and unless really warmed up(temp gauge 50 - 75 percent on gauge) it's just not crisp, slow to respond. Even when very warmed up, while it does respond noticeably better, it's lazy, not crisp at all, compared to my 1500 GW... This is just running in garage, not on the road. Wondering if it's fuel pump related. It's not backfiring so I believe it's getting adequate gas. Air mixture screws started out around 1.75 turns and are now about 2.75 or so. Turning them out did make it smooth out a little, but still not responsive.

Honestly I'm not sure if it's an electric issue or Carburation. I'm also wondering about the pulse generators, need to explore that topic more. New plugs have been gapped, intake/filter etc. all clean/new. LOL, I thought I'd have this thing slam dunked and I'm stumped. I've been successful with the 95 and getting it running, a couple of Valkyries I've owned and did the carbs, but this one has me at a stand still. What am I missing? Thoughts? Thanks in advance!

It runs smooth but seems flat? No shaking, backfiring? Vac advance hooked up,? valve timing correct?

See how it performs out on the road. Some CV carbs can act that way with no load.
Also check the accelerator pump function.

Thx fellas. I need to check the hose attachment between the #3carb and the pulse generator. The bike runs and starts very nice actually. Just doesn't like the throttle as the RPM's build somewhat slowly when I crack it open a bit. It gets better as it warms up but needs to get really warm to be even close to acceptable. No shaking/backfiring or acting like it's missing. Carbs were totally rebuilt/cleaned with ultrasonic cleaner piece by piece. Noticeable improvement over the way I got it, but just not quite there yet... Yea again this is all just setting in the garage, not out on the road. Again, my thanks....
