To do or not to do?
Bryanj:
Last 400 i did i had to remove a primary shaft bearing(bigish circlip) to move the spacer to allow the strter clutch assembly out, you dont need to do that on the 500.
Apart from that my hands are too big to get in to play with rollers, pins and springs.
Always a good idea to check out the cam chain tensioner horseshoe anyway, if the oil has been bad enough to do in the starter whats the pivot like?
Otis:
Many points acknowledged there, thank you.
Perhaps a life of kick starting is not such a bad choice in the end?
Laverda Dave:
I had to buy a bigger pair of circlip pliers to get that out last time I took a 400 apart. My normal SP circlip pliers just didn't have the strength in the handle, it would actually twist with the pressure. You don't want to be in way of it either if it lets go!
As for the cam tensioner horseshoe, I've never seen one that hasn't had some chain damage. The one sold by DSS is an excellent replacement having a proper pivot pin fitted, a shame the guy who makes them in South Africa and who is a member on here is unable to sell them direct due to the postage charges involved.

Having grown up in South Africa in the 1970's I would very much like to know who the SA chap is?
Bryanj:
It amazed me but the last 400 had black treacle inside, shot bores, bad valves but an undamaged horseshoe and pivoted fine----both retaining bolts needed helicoiling though!
