When I had my 83, I posted about my top speed being restricted to 85 mph. One of the responses had to do with washers welded in the exhaust pipes to cause a restriction. Now I have 1n 1987 GL1200I California Model and was wondering if they did the same thing to the 1200's in California. My 87 has 114,000 miles and is getting about 32-33 miles per gallon. Is this about right?
Retro48, as mentioned above, riding style (or lack there of) plays a big part in fuel economy. Velocity (speed) also can have a big input on fuel mileage. My 86 1200 will average out at around 39-42 MPG at a steady 55-60 MPH with few cold starts & very little stop & go. I go down to about 31 or so MPG at 90 MPH (my bike has a very high windshield though). When operated in the 95+ MPH range I haven't ever figured mileage but usually get under 100 miles per tank full.
In stop & go commuter riding during my daily run it runs closer to 32-33 MPG but there are some hills & sharp curves in that figuring.
I have worked with the carbs to get the bike to run good & not surge or stumble so that effected my mileage big time as I richened the pilot needles up. I am still tweaking the pilot system slightly but by leaning the pilot circuits slightly I can show a significant gain in light usage MPG.
I have a friend with an identical 86 Wing to mine (carbureted) & he has owned it since new. He claims that he has never got over 37 MPG & usually gets in the 34-36 MPG range. He is also a conservative rider (unlike me).
You ask..

Yes, due to the California emission controls the carbs were set differently & I believe that bike had a different crankcase ventilation set-up. Not sure how (or if) that effected MPG but it sure did on cars & trucks of that era.
