Hi everyone. Just wondering if anyone has fitted a sports exhaust system to their 250 Across?? I am trying to adapt a "Bandit" exhaust system that has a free flowing muffler to my 1992 Across to see if there is a performance increase, and the subject of carburetor jetting has been raised. If anyone has altered their system in the past, was there any requirement to re-jet the carbs to compensate for the additional air flow??? Graham.
