Technically (See standard text Rule Book page 103 section Section 7J.14) it would be Modified - Classic Gas - 500, On your...

(This is a Bones free Post :lol: ) Just a reminder to all potential Motorcycle Entrants that we now have a "Classic" Engine Class .....

Ron, indeed it will be interesting to compare what happens at Bonneville this Year with this Event on a number of fronts ....


Pete

Well Bolivia is run and done ...... From Scott Horner's FB page reports I have read Ack Attack's Equipment did not arrive on time so the Team's running was cut short and they ran out of time to achieve the Magic 400mph A few Gremlins and some Turbo Plumbing issues got in the way .... They reached 37...
