Hello everybody,
I came across this forum and want to let you know that I have built a full race bike with an Ascot engine in a CB250RS frame. I am competing in a classic bike race series in Germany and the bike is running quite successfuly l in the 500 pre 83 category. I have done a full race conversion to the engine with Wiseco 10.5 piston, Megacycle 144-21 valve train, head porting etc and it pulls 52 back wheel hp on a dynojet
