Looks great Roy, exciting times! That chrome plating sounds very cheap.

royhall:
Yep the chrome plating did work out cheaper than I expected. I very much doubt he would do it again at that price though.

Trigger:
Coming along well.
Does that clutch basket slide in easy as, the early 750's are easy to get in but the later engines had a interference fit and need to be pressed on the shaft while the engine is apart  ;)

royhall:
It was a bit half way, it didn't go on easy but it wasn't a press fit either sort of a really firm push.

royhall:
Got a few more bits fitted. The clutch assembly went back together okay using new friction plates and cleaned up original steel plates. The steel plates were checked on a surface plate and were found to be completely flat which was nice. The clutch basket is the one from the spare engine as it was like new, but to be fair the original was only slightly worn. At the same visit I also fitted the alternator and used a new sub harness as the original had hard and cracked insulation. I also required a NOS casing as the original was beyond saving with a hole where it had hit the road at some point that was filled with Araldite. The points cover is just a temporary old damaged one that I got off eBay for £3 in order to lay the engine on it's side to fit the frame.

I also fitted the new carb rubbers (don't they slip on easily when new). You will note from the photo that I was unable to source enough zinc plated clips. The outers are plated but the centre two are black. I'm hoping they will not be easily spotted once the tank is on, plus maybe some will show up before it's finished. I'm quite happy with it to be honest not looking too bad at all.

I would normally assemble the front end first whilst it's still on the box as it's easier to handle with the front weighted down. But due to a need to get on with it whilst waiting for some bits I did the back end. It was a bit of a fight to get the swingarm in the frame and had to remove some pretty thick powder coating. The problem was that when the bolt was fully tightened the arm went stiff to move, but I got there in the end. I should probably have removed all of the powder coating behind the bushes before fitting the arm, which I may still do at some point. I built up and fitted the rear brake, shocks, and drive chain at the same time.

Once the drive chain was on that allowed me to finish fitting all the engine cases. The next problem was the grab rail. As mine was missing I sourced a pattern part but unfortunately they only appear to do a rail for the older bikes (up to K2 I think). This is fitted with indicator mounts for the much slimmer stems of the older bike. The challenge now is to find a way to fit the later thick stems to the older bracket, but I will find a way that wont be noticed (except I just told you all so the games up).  ;D
