Greetings,
I have a friend's Commando here for a cosmetic going over and while putting a parts list together I thought of changing the subject retaining plates out or replating them.

My question is whether these plates are able to be changed, removed and replaced Without disturbing the rocker spindles..? Simply swapping them out.

This thing runs great and I hate to mess with valve lash or have an adverse effect on the running of the engine just for cosmetics.

Thanks much,
Rob

easy change, the hardest part can be scraping the old gaskets off. also will not effect the valve lash but it is a good idea to check from time to time along with cylinder head torque.

Bill,
Great, so I plan to only swap out the plates, not the Lock Plates so I was hoping for an easy change. I do plan to check valves at some point as well but did not want to disturb the shafts if I could possibly help it.

I also plan to pull it down to inspect and probably replace the Iso mounts, at least the gaiters so it's not as if I won't be doing some major surgery... This entire day has been spent building the parts list required for all the stuff that the owner wants done.

Thanks much,
Rob

even when you remove the lock plates you wont disturb the spindles as they should be a light press fit. i don;t like to run the gaitors on the iso's, they have a habit of holding water and rusting the metal parts and most of the replacements are of poor quality.

Good to know regarding the lock plates.

Interesting about the gaiters, these are a bit hardened and really do not do much for water and dust exclusion, I'll take it under advisement and ask the owner what he wants to do.

Thanks,
Rob
