The damned rear caliper is still dragging after my rebuilding and many adjustments. I am wondering if I could have a blockage in the rear brake line. My machine is over 7 years old and the brake line runs under the engine along the frame where it has to endure the heat and elements. I wonder if it has deteriated and has a blockage inside the rear brake line??

Have you put a piston in your machine? I think I am close by the way it is running. What is the acceptable compression? I assume when you get a compression drop it is timne for a piston and rings?? I used to race motorcross (Honda CRs) and I would have to put a piston in those two-stroke motors when the compression dropped due to nbormal wear.
Do you have to remove the engine to put a piston in? It looks pretty close to the the top frame so getting the jug off may be tight?

I think my startere is going also. Have you replaced one of those?

 

Hard to determine what is wrong with the brakes with out putting "hands on". They do have a small amount of drag. Are you sure yours is eccessive?
Hard to start and getting low on power? If so time for a piston. Can be replaced with engine in the frame in a few hours, real simple job. Wiesco pistons seem to be the popular set up.
Never had to replace complete starter(pricey), just brushes, armatures and drives(also pricey).
Good luck, Bill

 

I may just need to let the brakes drag a while and see if they break in. It is hard to know what excessive drag is.
I am going to have to do the Weisco pistion change.
Thanks for all the advice.
Did you have to pull the motor to remove the starter?

 

Dont have to pull the motor to remove starter, but do have to remove inner clutch housing.

 

Is the inner clutch housing easy to remove?
