BVM pipe help needed
I have a question concerning the BVM 'puffer' pipe. I have an OS91 and I recently acquired the BVM puffer pipe. I installed it on the 91 and it felt somewhat loose. I tightened the hex screw on the pipe and it is still loose. Will this pipe work with the 91's standard exhaust adapter??? Do I need to get an adapter from BVM??? Thanks in advance for the info...
