RE: [rokon] Another CT rokon

Go ahead and split the cases...with no transmission to worry about there
is very little difficulty...very possible the crank/lower bear is rusted
up and the crank probably needs rebuilding which is not that big a
problem...but go ahead and find out the worse now and get it taken care
of.

Subject: [rokon] Another CT rokon


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

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...
