Another way to "help" the chemicals do their job is to apply heat. A heat gun
works wonders. Helps to soften the sludge and deposits. Perhaps you have a local
auto parts store that has Beerryman's in the gallon pail. It's a carburetor dip
solution. My only concern with anything that strong would be crank seal damage.
Honestly at this point in time, The crank seals are probably toast anyway. If
you slpit the cases, you can service the crank and inspect all the components.
Along with replacing the seals. Cheap insurance given the pistons fot them are
becoming rather hard to come by.

Glad to hear yet another classic will be among the living.

Hello, I am in CT, and am a long time Trailbreaker rider. I finally bought a
nice low miles RT340. Unfortunately, it sat with fuel in the tank, which dripped
down into the engine. The cylinder is in excellent shape, piston too, but there
is dried brown goo on the flywheels, and the crank does not move. Dried out fuel
residue binding it up? I have the sump filled with WD40 now. I am thinking
something stronger. I know that I should take the crank out to truly clean it
the right way.....  About all I need besides that is a rear fender, mine got
shortened some time in its life. Hal in CT
