It would only take a couple of weeks and then we would be porting heads, boring out our 250 to 266, lol
getting rid of that one barrel 20 mm carb for a good mikuni 32....I can see it now.......

hurr 15 like i said , same mods as the 440 , you can port and polish them! and run a different carb like the 440! As for displacement guys could cheat buy boring 440s out too 570s (different jugs) it all depends on how they are tec ed. Cheeting is always gonna happen , u just have to catch it! Displacement is easy to check, so as for your thoughs it can be  easily monitored. 

One of the reasons i got out of the "Sprint Class" was due to the "Old ways" of thinking, these points all have meritt, i do hope that as you all look at changes, look towards a motor package that will benefit larger people, as in having a left side or right side drive. Having a motorcyle engine/transmission is a great step toward a future. Also look at the frames, you may want to look toward chrome moly tubing for superior strength.

Sorry for my input, hope i havent offended anyone.

    Let me say that I really enjoy racing 440,s But on the other hand,  yes its time for a change...
      we should be all able to race together regardless of suspension or non suspension, 
  I would like to see similar to the u.s. (wider choices) 600 cc,s and by the way its the year 2007, everybody should have electric start.
  although there are still 440 motors available,  its time to open the variety up a little bit
      I am joining the grand bend group in 2009, cause my daughter will be turning 10 and she wants to get involved, So next year will be the last with the hurricanes for me.....
   

If anybody has rolling chassis for 6.5 hp mini sprints,  let me know please, for 9 year old girl
