I got the ignition system installed and I was dying to hear this thing run, so I hot wired it. This motor has great compression and is very difficult to turn over with the kick-starter even with my 230lbs behind it, but it still started up first kick!

I decided to scrap the custom foot-pegs I was working on and modify the stock brackets to use Tarozzi pegs, I also turned some aluminum spacers so they are solid mounted now. all that remains is wiring, fuel plumbing, and a license plate holder. gettin close!

forgot to some add these pics of the new shifter. I went a little overboard on the speed holes with the stock shifter so I re-made it out of thin wall steel tube, and TIG brazed the fittings on. It threads into an aluminum Tarozzi splined clamp.

I'd like to get some opinions here as I have compromised the strength of a semi-structural screw and I don't want my own "genius" to kill me. I drilled and tapped this head-stock screw to mount an oil light. The difference between the OD minor thread diameter and the ID major thread diameter is about 4mm so I am left with 2mm thick walls. This screw appears to pretty lightly loaded as the steering stem fits into the top triple and is firmly clamped with a pinch bolt. I torqued the modified screw to the factory value of 36ft/lbs and it seems fine. I have also seen aluminum aftermarket replacement screws available for this application so I can't imagine that this is super critical strength wise. thoughts?

My thought is the bolt is used to make sure the the top clamp is fully pulled down onto the stem before being locked into place by the pinch bolt,

I cant see how it would cause any catastrophic failure

A M16 screw can torque up to 240 Nm at 8.8 grade fine pitch.
You are on the save side.
