Rascal - That's one seriously cool looking hot-rod F1!

I'm looking forward (obviously) to the DB1 pics. Where are you located?

Regards,

It is "interesting" to see your modified ignition system for your TT 2 Steve. I was experimenting with and developing a similar system during the winter of 1983/4. I had experimented with standard Bosh pick up's, and also pick up's and amplifiers from a krober marine ignition unit, and also a Motoplat unit. During the development I also played about with a outside flywheel. however my development work came to an end in 1985. How does yours run ?

regards,

Pat.

Hi Steve,
At present i am located in Brisbane Australia, next month move to Perth in Western Australia,

Hi Pat,
My ignition (Dyna to suit a Kawasaki Z900) runs off the cam cross-over drive, drilled & tapped the shaft to fit the trigger unit, the pick-ups mounted 135 degrees apart mounted on a triangular plate that i fabricated to bolt to the mounts where the original cam belt covers would normally be attached to. on this plate a separate disc is fitted to advance/retard the ignition.
On the photograph, where the breather pipe is attached, i now have a tiny gear pump fitted for a "water injection" system, (atomisers over the FCR intake trumpets which are in a sealed airbox/ram air system)The plan is to use a blend of nitro-methane/methanol & water mix, instead of just water !!
Hope it holds together !

Regards

Hi Rascal, everytime I look at your bike I seem something different! Tell us about your rising rate suspension and exhaust will you? Lou

Hi Lou,
Firstly a bit of background, I based my TT2 on a picture i had of a New Zealand international road racer, Robert Holden, who sadly lost his life at the Isle of Man TT races in 1996.
The picture was of his nitro/methanol burning TT2 wheelstanding, showing the underslung rear suspension. ( as a side note one of the best race finishes i have seen with Robert on the TT2, competing at Wanganui street races in NZ, against another top NZ racer Bob Toomey on a GSXR1100, AWESOME.
After aquiring a replica TT2 frame, i put the plan into action.
My design of the rear suspension, obviously using a underslung shock, I welded alloy plates to the swingarm's original shock mount,then machined these to fit machined bearing carriers, supporting an eccentric shaft that partially rotates as the suspension is compressed, thus giving a rising rate.
As stated earlier all the linkage units are machined from 7075 aircraft alloy, needle roller bearings etc.
As for the exhaust system, what with cutting down the crankshafts overall length, i wanted the bike as slim as i could get it. not that easy on a TT2 frame with modern engine(wrong way cyl heads) as the space available is limited for exhausts etc.
So i set upon the lengthy task of fabricating the exhaust, routing it through the frame/engine with the required equal length headers ( got within 15ml of water between front/rear pipes) 44.5mm dia merging to 51mm then to reverse cone megaphones with custom made removable bolt on silencers?( not that quiet!! but acceptable)
It was pretty much 3 years in the making & still have a few more modifications to come. :D
Regards
