    I used the titanium mounts from Nichols also.

    Either solution will work, I did this to avoid changing the frame .. ie if an older engine would go back in some day.
    Most people will go with st4s original electronics, I have now made 2 bikes with dual pick up and P08 box w 996 SPS Eprom .. time consuming to find the bits, but works very well.

    I also used the Nicholls engine studs but...
    I drilled the frame and the 851 cases out to 12mm, so that I could swap between that and my later 12mm cased motor.

    I use the Nichols 12mm bolts and drilled the engine cases out. BTW, Nichols bolts are not titanium, only the nuts. The bolts are tool steel ground to size

    I wanted to keep it pretty straight forward to understand but also easy to tune, so I kept as much stock(ish) ST4S as possible--loom, throttle bodies, etc. I eliminated some wiring bloat like the immobilizer, switched to the analog temp gauge, and switched to more svelte superbike handlebar switches. For the throttle bodies I had the stock injectors bored out/cleaned/matched. I think I also bumped the fuel pressure half a bar with an aftermarket regulator. And then the Microtec ECU is plug and play for the original 59M. Too hard to get chips tuned and burned these days. Was also able to incorporate a quickshifter.
