Hi after a quick scan it looks to be of the correct design.
But would require some of the missing chassis members to be added. Which ARE legal for the championship.
cheers matt

The ONLY way to learn about any racing is to attend. Nobody gives anything away unless they have met you in person. Most will talk when addressed
politely!
At least this is the case for mountain bike racing in my part of the world.

Yes, I've built my 750mc spec chassis using those plans.
The things to be aware of are - "_f" will move 1.5" more outboard ( 3.5" from the centre line rather than 2" ) for a
book tunnel. You may also want to modify "O2" so it lines up with "_f" as a result (I didn't bother, I doubt it
matters.)
Once you have got through those plans you have to use the book (and a bit of imagination because the top layer plans don't match the bottom
layer) for the transmission tunnel.
You can, but don't have to, add the 3 extra rails shown in the 750mc regs.
And lastly weld in TR1, TR2, TR3, TR4, TR5 and TR6 from the book.
