For all you watchers!! This is a very competitive engine!
I have personally tried the Karma Limited Ed. w/ lowered silver cooling head and really like its performance versatility. I however swapped the 7mm carb out for a 9mm carb from a Rossi Plus 21-4 bttwc/a and still use a 6.5mm venturi. It does run fine with the stock carb, but it opens up more power with the 9mm carb. Using a Novarossi nvr41021 header with a Jammin Products JP-1 pipe gives the Karma a TON of low end power.. using a novarossi nvr51020M (2096) pipe will give it a smooth and powerful low end and a very strong bursty mid and upper throttle range. Its even better when swapped to ceramic bearings! Its a great bang for the buck in my book, I have it as my main race engine! It keeps a very reliable tune. It has the lowered head crankcase so any Novarossi .21 lowered cooling head will interchange on it!
