[QUOTE="greg brillus, post: 179177, member: 597"] With the classic racing, it is difficult to point any finger when describing if one is "Cheating " or not, as the rules vary from country to country. In Australia we can run "Any kind of drum brake so long as its drum diameter does not exceed 230 mm".......This would be seen as wrong in the UK or Usa......In reality it is a big "Limiter" in a way......I see it as a safety feature.......Given the bikes go much better than they did back in the day. Some items that seem incorrect, but totally over looked by many old school boys........I'm running a Keihin round slide racing carby.......most look at that as cheating because it is too modern this verses say an Amal TT or GP.......but in our rule books it is perfectly ok to use one, and it even mentions this carby to use.......Engine mods are pretty much open, so long as you cannot visually see it externally......I used to be a huge fan of the Irving Vincent's and still am to some degree.......But I would not like to compete against them......Despite what others might think, their bikes are really cheating at the highest level........If we all had a full CNC machine shop just think of the bikes we could create.......Ken and Barry are very smart guys who have built some amazing machines........but they show no interest in helping anyone or making anything Vincent related to help the Vincent world......It is for that very reason than a friend and I decided to make everything ourselves.......I have gone to some detail to explain what we have done, and will be happy to soon enough.......I just wanted some more actual run time to prove the engine some reliability and endurance......I know for a fact I am never going to be able to ride like Beau Beaton or Cam Donald.......But just building a big single that can hold its own against other Brit twins is more than enough fun for me.......The issue the Horners have is keeping a big HP engine cool.......When running certain fuels, there are types of micro detonation that sends shock waves through the connecting rods........these then ultimately fail.......I feel this might be part of their problem......It is one thing to carry out mods that could be seen as cheating.......I think it is just mankind trying to outdo each other anyway they can whilst getting away with it.........No one in the classic bike field really gives a toss these days.......the numbers of classic bikes racing is dropping off in big numbers all over the place.......Geoff Clatworthy's ES 4 Norton is anything but legal, but at over 60 RWHP and 107 kg's in weight with years of dedication to making a pushrod single quicker than a Manx.......his efforts are outstanding.......Its just a bit of fun.......madness but fun.
