First i would like to say, WOW! Yesterday, i did all the free mods, AIS, promoto-billet, zip-ty and rejetted by carb with the jd kit / pilot. The bike is an absolute rocket now. The power increase was way greater than my expectations....awesome!! But, i have potential problem with the AIS removal kit...the AIS exhaust plug does not clamp down tight...let me explain... i put it on and it was snug and tight...then i took it off wanting to make sure that it was perfectly installed...but this time, regardless of how tight i make the clamp or where the clamp is on the plug, i can still spin it or pull it off with a little force. It is like there is a graphite film on the exhaust port. I even went to home depot and bought another clamp. same result. questions: 1) does that exhaust port blow a lot of pressure and will i likely lose the plug if i ride? 2) Has anyone else experienced the same thing? 3) Any suggestions to fix my problem...ie> heat tolerant "glue" or something like that. I have read that some have threaded the pipe and put a screw cap on, but that is way beyond my mechanical abilities. 4) WHat happens if it comes off during a ride? any feedback is welcomed. thanks. ken.
