Well this is all most impressive, just wish I'd taken metal-work at school. However, having struggled with completing the tea pot stand in woodwork I wasn't allowed to move on to the tea tray, so I doubt they'd have let me do metal-work anyway. Shame. I'd love to be able to do this sort of thing.

Put the wheels on. Still a billion things to do but for now I will focus on getting the engine in.

Santa Came Early:
Picked up a set of FCR's locally. Now I have to find some throttle cables or at least their dimensions.

Oh it's been a while, so better do something about that.
Decided I wasn't happy with the main bearing restrictors. If they work loose they can just fall into the lower gallery and that would be the the end of the engine. My solution was to turn down a couple of ultra low head cap screws.

Left to right, OEM restrictor, ULH cap screw, drilled & narrowed.

and here it is fitted. That will work for me.

Next task was to make a press to get the bearings off the gearbox.

Gearbox:
So the gearbox is finished and ready to go. New bearings, thrust washers, circlips, seals and Superfinished. I mock fitted the cases together today to check all the bolts. Some are a bit stiff so I will tidy that up and check again. I sent a couple of hose/cable brackets away with some Honda stuff to be nickel plated. When it comes back I will bolt the cases together. OMG the engine in the Yamaha is going to be a shock to the system.

Well done for sticking with it, it'll get there.
