DCOEs are great carbs, but you have to remember one main thing, it has to be matched perfectly to the engine in question! It is not an ear tuning job! It's your money, but I would take the advice of others and stick with the SUs, you'll save money and get a more simple set up that gets the best performance out of a stock engine with very little effort. Just my opinion but, SUs were one of the finest carburetors ever designed and simplest to work on once you understand them. The motor cycle industry copied the design years ago and it's been very successful, even to this day. PJ
