I have a new rt crab from dax. You have to use the old throttle cap off NT carb and put it on top of the new RT for the throttle line to work correctly. My question is even though this will work and hold the throttle cable in fine, if there is a slight gap of any sort where this threads into the top of the carb, if that is considered a intake leak also that would effect the running of the bike or is it only when you have a intake leak on the intake itself or where the carb bolts up to the intake that causes problems? Thank you.
