Crankshaft is back again and allowed me to take the measurements needed to finish the drawing for the crankshaft pulley. Found a company, on the internet, in this country that is able to turn the pulley out of 7075-T6 round stock and cut the 30 AT10 teeth that I think I need. Once that is done I will get the local guy here to cut out the internal splines with his Wire Electro Discharge Machine and then the final touch will be hard anodizing of the complete unit.  All this as punishment for having chosen this trick 270 degree crankshaft – let´s see if it was worth all the extra effort and money????

The last month I was mostly idle as I found it hard to mobilize enough energy to take care of the various small but tedious details that are still missing, one of them being the head steady, or cylinder head engine mount. I had been reassured by various sources that this mount is absolutely necessary to avoid various vibration and even handling issues. The problem was how to connect the cylinder head to the frame as I had no real means of brazing any brackets to the frame tubes. I finally came up with designing 3 brackets, one attached to the cylinder head, the other two to a transverse frame tube and connecting them with each other by nuts and bolts. This design should be able to absorb forces acting both back and forth as well as sideways. Not very elegant but the best I could come up with. Below a couple of pictures for you to see the result.

Have also ordered a start ramp so I can sit comfortably on the bike when starting the engine. The ramp has two small diameter rollers that spin up the rear wheel and I, theoretically at least, just need to put ii a gear and ease the clutch out and brmmm. The rollers are driven by an AC motor and to bring juice to that out in the field I need a GPU ( Ground Power Unit ).  That was also procured and arrived this week. Max 3.8 kW of 230 Volt output and enough to start the motor.

This is what it looks like:

I start to see the light at the end of the tunnel. Just another dozen or so things to be done but I trust I will be able to take part in my first “race” in Hungary on May 4-6. Keep your fingers crossed!
