can't even get the tuning right for this carb maybe due to my hot wheather
I always use 5.4 ventury. Im not saying its the best but when i first switched to BTTS, i started with 5.4 and 9901 pipe and stick with them. Never tried other combination. I find it 'easier' to tune when its closer to sea level with 65 But when i race on higher ground, i'd rather use 63. Anybody know anything about 69 carb?
