In the general forum, I asked for a full set of rules for the new Dinosaur class, not realizing that I had already read the full set, assuming what I had read was an outline for further, in depth breakdowns.
So, since their aren't, and the current ruleset is ambiguous at best, I'd like to ask a few questions, pulling some specifics from the previous section 'O'.
From 'O':
Dino Rules:e) Frames: Must be consistent with the period.
These sorta overlap... But it seems implied that the dino class has more leniency in terms of modifications.. Is this the intention?1)All modifications are permitted providing they conform to the regulations and vintage intent and are consistent with safety.
From 'O':
Does this carry over to Dino?Swingarms may be strengthened
by one or both of the following methods only:
_ the addition of gussets
_ the addition of other material directly to the swingarm so as to not
increase its overall height or profile beyond 1/2" greater than the
original stock swingarm.
_ No “superstructures” may be added as part of any strengthening.
The swingarm can be 1 x 2 rectangular steel tubing.
From 'O'
Nothing is mentioned about rim width in the Dino rules. So, does this stand? It also doesn't address the issue of Mags or mag-type wheels, which were available on bikes in '77.3) All classes may substitute modern treaded racing tires with rims to suit. Maximum wheel rim width is WM5 (2.75-3.00), minimum rim diameter is 18 inches, except where originally-fitted with smaller diameter wheels.
From 'O'
Does4) Cylinder(s) overbore limit is 0.060 inches.
mean that a bike of any size be bored out .060, or does it mean that any bike can be taken as large as we care to do so?Street based motorcycles having unlimited displacement,
I have more questions, but I'll start with these.
