7.G SPECIAL CONSTRUCTION
7.G.11 Partial Streamlining:
No part of the fairing ahead of the front axle may be lower than the top of the front rim at the axle vertical
centerline or be forward of the front edge of the rim. There shall be no streamlining forward of the front
edge of the front rim.
I think this rule is pretty clear.
Put a Third Wheel on it maybe?

Fill in what you loose with a front mudguard and things could look pretty good again

Re: rule guideance please
yep. with a bit of modelling and taking advantage of the rule differences between the States and here I think that as you say, a front mudguard and a few other changes would recover what was lost.
Interesting though that a bike that is legal in the USA and holds the record for a 125cc (42hp) at 141 MPH is not legal for the rules here.
Is APS the only class difference between the two rule books? and why did it evolve to be that way?
But never mind although it would have been nice to be able to directly use the developments of someone else (and known wind tunnel data) I guess I was always going to have to do it alone anyway........

Re: rule guidance please
Don't forget there are 3 sets of rules in use there,SCTA, AMA and FIM with common backgrounds but still have variations between them

The DLRA run SCTA rules. So if you don't go to the States to run then you really have one Rule Book the DLRA.
The DLRA and the SCTA are specialist Land Speed Racing organisations that have Car and Motorcycle Regulations.
The other two are Motorcycling Governing Bodies that have a number of different regulations ( MX, Road Race etc) and have a set that relate to Motorcycle Land Speed Racing.
The AMA is a USA organisation.
The FIM is Motorcycling's Worldwide Governing body and these are the rules used for an "Official" World Land Speed Record.
If you are planning to run at Bonneville at Speedweek, WOS, World Finals or at El Mirage, these events run SCTA rules, the same rules we run, so that option is fairly straightforward Rule wise.
The difficulty emerges if you want to run something other than these events.
If you want to run at BUB then you have to decide if you want to run an AMA Class and Record or an FIM Class Record.
While at The Shootout it's all FIM Class "World Records".
I think I got that right

Re: rule guidance please
i recall checking that bike out at BUB's a cuppla years ago, nice piece, ,,
yes, it is built to fit the AMA rules which state that 180* of the wheel must be visable and the frount fairing is allowed to be 2" ahead of the tyre,,
with a little imagination you could reshape the nose section to fit within the DLRA rules,, i would suggest that you piss that porthole window off, and put a full length screen in,, at speed you will have enough to worrie about, the concentration needed to keep ya on track could be better used elsewhere, ,,
