So can I fit conventional forks from a 1998 RM 250 to my 1979 RM 250 ? I will fabricate a bracket to hold the front brake backing plate and bolt it to the caliper mounts .
Bill, short no as you need to make a bracket for it to fit. That would be covered by the fact that you have modified to fit and not OEM, also you cannot run disk brake on evo as it states this clearly in the rules.
That is what makes the Honda (in the case of the 79) legal as you do not have to modify anything. The thing that came up earlier about fitting 500 engines to the 79 is also a joke as you would need to modify the engine mounts (and most off all the frame) to fit these and that is also against the current and proposed rules. The rule states that engines and gearbox must remain externally unchanged as I am entering a 79 CR 250 the engine would have to be a 78 or 79 CR 250 and not a 450 or 480 engine as these differ, for that point I can't even fit a 80 CR 250 engine as the barrel differs.
As for the rule changes I am not sure as to why these are being put forward. Evo has works well for the last 10 years with the current rules and I see no reason to change them.
No one has yet pointed out to me as to how I am reading my interpretation of the rule wrong. Not their point of view but how it is wrong via the current rules?
I am not trying to shit stir I was answering a question that was asked at the start of this thread and as usual all the so call experts have put in their two bobs worth without looking at the facts.
I am not going to post again on this topic as I have covered and expanded all my points of view. I did say about 8 pages ago this thread should be put to bead as it has turned out like the last thread pre the nats.
I will beg to differ with some of you on here as it is your point of view and you are entitled to it.
