7) If Right pipe [sitting on bike] smokes more than left crank seals will need to be replaced  

    For GOD sake this is a 35-39 year old bike rubber parts wear out due to many years of    exposure.

 If seals need to be replaced Jetting will be a bitch -left side FAT jetting right side LEAN jetting. If  the labyrinth seal is weak both sides will smoke.


8) Noise in the engine - Slappy pistons will make noise- Ride the Bitch.

    When you are riding and it slows down and will not start. Wait for 10 minutes then start and go home you have just experienced a seizure. Medication for this is a new top end! YEY!!



Off you and your wallet go, new tires, chain and sprockets, brake rebuilds, rubber parts, new odds and ends. YourWifehas to love you a lot or the bike for this to work... Once you ride a well tuned RD you will find it is not the fastest bike out there. But is sure is fun, power band is an addicting thing on these bikes

     

              




                    Have fun
