GL1100 carb rebuild or not?

Post by bbcline1991 »



I recently bought a 1982 GL 1100 aspencade. It was sitting for about 4 or 5 months in the previous owners garage. The bike currently has 40,000 km on it. When I bought it, it would not start. After rewiring the solenoid and rectifier regulator and doing a fuel flush, the bike starts, idles well and revs high with no knocking or sputtering. The bike only has 40,000 km on it and no running issues. My question is should I do a carb rebuild or not? How often would you recommend to do a carb clean on these bikes?

starts well ?
idles well ?
revs up nicely and drops back down to idle when throttle released ?
don't fix it until it breaks ... been there, done that.

Agreed! If the bike is running well and your gas mileage is what you expect a rebuild is time and money wasted.
It's difficult for a man to understand something when his salary depends on his not understanding it.

I agree. If it ain't broke, don't fix it. What I would do is change all fluids, change timing belts (due to age not mileage) and check age and condition of tires. After that, enjoy your ride.

I kept my 82's carbs clean by dosing it with Berryman B12 periodically.
1/2 can into a half tank of gas, ride normally for 40 miles or so, then top it off with ethanol free gas if you can find that.

Since it's new to you, it wouldn't be a bad idea to drain the carb bowls and see what comes out.
Certainly wouldn't try to fix what isn't broken either, RIDE IT!


When all else fails, RTFM!
