Carb Float Level Adjustment 1983 GL1100

Postby Bshef » Mon Mar 22, 2010 9:23 am

I just rebuilt the carbs on my 1983 GL1100A. They worked great for a little while but no I have two carbs that are running over with fuel. I pulled the carbs back off the bike to recheck the float levels. My question is do you check the float levels with the spring in the needle valve compressed or relaxed, with the float just resting on the spring. The spec I have for float level is 15.5mm or .610" from bottom of float to carb flange. Thanks for any help, Bshef

I set my float levels to the measurement you noted with the plenum face vertical. That had the floats just resting on the spring loaded pin without compressing the spring. I found a carb how-to tutorial, with detailed pictures, on the net. When I first fired up the bike I had one float bowl overflowing but a few careful taps on the carb, with the handle of a large screwdriver, took care of the overflow and it hasn't been a problem since. I've now rode the bike 100+ miles without another overflow problem. I won't say what I did was right, but it seems to have worked for me.

Here's the how-to that I found to be the most complete and helpful...
