Hi Jaguar,
I have run the bike in many differn't specs. Started off with it as my road bike, with lights and a half fairing. Ran it normally aspirated in 750 form. Used it in sprints and made 152 mph (at 12,000 rpm - not to be recommended for long) with a piper race cam and exhaust and the head polished ( 28mm carbs, as far as I remember) 12.1 compression.
Then I took it up to 998 cc ( new pistons and liners, using a 750 block bored out and the crankcases bored to match). 2mm oversize stainless inlet valves were installed ( standard exhaust valves), S&S race valve springs and the head flowed to match.
Result, 161mph with the half fairing at the end of a kilometer. Used the bike in this form for 2 road races and then sat on a wall to watch Irish landspeed records being set by Danny Keany, OWOI 750cc works Yamaha ( 167 mph) and by Vivian Candy in an Arrows F1 car ( 169 mph).
Felt that I could do better than that and then got serious.
The concept was to keep the weight down, have very efficient streamlining and produce more firepower than anything else running in my country at the time and run it all on a low budget. The only way to go was turbo (modified ATP Rajay FF40) and why not add nitrous for good luck as well? ( In reality the nitrous never worked out. At about 190mph I used to hit the button but the clutch always slipped. A 2 extra plate racing clutch, the best available then, was used but, no good with the nitrous. A nice lock up would have been the thing to have but, not available then.
The streamlining proved efficient and it ran 165 - 166 with no boost ( about 80 BHP). Compression 9:1.
I will post some shots of the internals and the mechanics in the near future. If you have specific questions - just ask.
Good luck.
