Motorcycle Repair: Yamaha seized engine and bad starter, yahama virago, sympatico ca


Question
I have a 1982 Yahama Virago XV750 motorcycle.
In the 12 years that I have owned the bike no engine repairs have been made nor are there any performance parts that have been installed. It sat for 5-6 years without being started and now seems to be seized up.
1.  Are there any internal parts that (valves stuck open) that could keep the engine fron turning?
2.  Other than rings having seized to the cylinders what are the other places I need to check to free up the engine?
3.  Persistent starter problems.  Two spacers have been added.  Starter still bouncing out of gears and spinning freely. Is there a fix?
4.  The last time I tried to start the cycle the starting motor got hot and didn't seem to turn as fast as before.  Can the starting motor be repaired?  Or do I need to find a replacement starting motor.

Answer
Hi Paul,

1.  Are there any internal parts that (valves stuck open) that could keep the engine fron turning?

A:  Valves rusted to their seats, bearings rusted to shafts.


2.  Other than rings having seized to the cylinders what are the other places I need to check to free up the engine?

A:  Again...valves rusted to their seats, bearings rusted to shafts.


3.  Persistent starter problems.  Two spacers have been added. Starter still bouncing out of gears and spinning freely. Is there a fix?

4.  The last time I tried to start the cycle the starting motor got hot and didn't seem to turn as fast as before.  Can the starting motor be repaired?  Or do I need to find a replacement starting motor.

A:  The motor's carbon brushes are likely worn and the resulting carbon powder has no where to go but insdie the filed of the motor. There, it can create mechanical resistance to turn easily, and can cunduct electricity.

I think removing, disassembling, and cleaning of the starter motor may restore proper performace. If not, it's time to replace it.
