Carb(s)

 


I have a 1987 GL1200 Aspencade that has four carbs in dire need of cleaning.
What's the best cleaner to use?  If I remove and soak?

If it is still running at all, first try twice the recommended rate of
cleaner in 1/2 tank of gas and run it for a while.  Gumout Original Carb.
and Choke cleaner is good; so is Berryman's B12.  If that helps, then fill
the tank, ride and pray.  Finishing that tank and maybe another with the
cleaner may just do the trick.

Both those products are good for remove and soak too.......if it comes to
that.

 


I don't recommend actually *soaking* even the filthiest, most gummed
up carbs, as you might destroy old rubber parts that have yet
perished.

Use aerosol Berryman B-12, STP, or GumOut carb cleaner and spray the
carbs with it. Those carb cleaners contain acetone, toluene, and
methyl alcohols and they are fast acting.

If you have some kind of flat metal pan that will hold the carbs, you
can use a brush to scrub the carbs with the cleaner that runs off them
as you spray them.

That's as close as I ever get to actually immersing a motorycle carb
in cleaner.

If you want to clean the carbs internally as you ride, pour 4 or 5
ounces of B12 into a fuel tank of fresh gas. Don't get any on your
paint.

You'll know the B12 is doing its job if the idle RPM increases while
you're riding slowly to keep the engine running off the idle jets.

You should know where the idle adjustment is before riding with carb
cleaner in the gasoline.

 

i have fuel dumping from a tube on the air cleaner on my 82 seca 750.
could that be from a stuck float?

also seca tanks don't have an off. just on, res, and pri. the only way
i could stop the flow was by pinching the tube
