Sprocket:
Ah right, the procedure in the book of words said to slack off the bolt (and let it adjust itself) when the engine was running. I suppose I could do that before I start it to get it most of the way there. I'm concerned the running in process is going to be a bit frantic enough though!

Carbs will have to be bench-balanced, sparks will have to be 'almost right' and hope everything holds together for 10 mins run!  :o

Nurse Julie:
Agree, the book of words does say that. But, once you get the bike fired up, the last thing you want to do is have it sitting running, getting very hot, whilst you fettle and adjust things. It's best to do as much as you can before even starting the engine for the 1st time, so you can ride away, getting air round the engine to keep the engine temp down. Fine adjustments to carbs, cam chain etc can be done when the bike is well run in.

Sprocket:
:) Sheepishly looking forward to it now! Thank you!

Nurse Julie:
It will be very exciting for you. Dont do the first ride on a hot day. Just don't let her get too hot, I know you have new pistons and rings, so you need a lit of cool air around the top end to avoid over heating and seizure whilst running in. Just make sure when you fire her up that you have oil getting to the top end by removing a tappet cap at each end and watch for splashes / specs of oil. If you don't see this, stop the engine and investigate / rectify or you could cook your top end 😱😱😱

Bryanj:
If you adjust it the way i did for all my years in the trade it will be OK to run for quite a few miles.
1 loosen lock nut
2 loosen lock bolt
3 put weight on kickstart so that you can feel engine about to turn over
4 whilst holding this position nip up lockbolt
5 let go kickstart and nip up locknut

This pulls the front run tight and has all the slack in the side with adjuster blade so if horseshoe free and decent springs on pusher it should be OK
