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.

Finally had the time to cut and buff the paint. The result is dead flat with no definition line over the stripes. I also put on the badges.Ive been tinkering with the wiring off and on for months and it is finished. I did a bit of driveway tuning learned about the one year specific pilot screws to this year. Rounded up the nessecary parts and it's synced and seems to run great. All that remains to sort is an axle and a license plate. The latter of which should be here ina week or so.

First ride was a reasonable success! its got just enough power to be pretty fun, the exhaust has a great tone to it. Not too loud at idle but pretty rowdy when you get on it. The brakes are fantastic. I rode it to my graduation and hooned around a bit there afterwards with my robes on, my parents think I'm crazy. I put about 70 miles on it yesterday.

The jetting is pretty close, think I may need to go one bigger on the main and down a notch on the needle. I'm running into what i think is fuel starvation. When I'm on the highway, after a several seconds of going WOT its starts to miss and wont accelerate anymore like its running out of gas. if i back off for a bit and cruise, it seems like the float bowls refill and I can go WOT for a bit again until it starts missing again. WOT pulls from a stop to 5th gear are no problem its the extended WOT at 60+ where it happens. I have a cheapo petcock, I'm wondering if its not passing fuel fast enough. suggestions?
