Sorry to disappoint you but Dad and I have come to the conclusion that the clutch springs are just weak. They lack the appropriate clamping force to do the job all the time. Sometimes the engines and clutches do fine, but other times when riding it hard they will slip in 5th, 4th, sometimes even 3rd. Ours have been adjusted and motorcycle oil filled, but to no avail. I figure when there is good cause to go into the engine, I'll just replace the springs.
