I just toook my aaen quads off my '93 750 for cleaning and painting so I figured Id pass along a few things that I noticed. First off if you're ever confused which pipe goes to which cylinder, they have little raised spots of weld about 4-5 inches, 10-12cm, back from start of the pipe. Just after the spring tabs, if you dont see any spots at all thats #1, stator side. I found installing number 2 first helped me get them back in alot easier. This followed by #1, #3, and #4. I found that getting them close at first was preferable to snugging them right up. I also found that w/out a little spring ingenuity, the #1 pipe, the only one to exit stock hole rubbed against the chaincase. Easy fix however, just need to make sure springs are installed to "pull" pipe away from chaincase. The last thing that should be done as far as I can tell is to reroute the drain hose that comes from the bottom of the rad tray. In its stock poistion it will be burned up by the aaen's. As far as jetting is concerned I'm still working on it. I have 140 mains installed right now, up from 135's, but they are a touch lean for my liking, they work fine up to about -5 celcius, and better the warmer it is. I have 145's on the way that I will be trying as the temperature here is -20 celcius quite often. I didnt change any other jets. She idles and starts fine and the mid range is great. I just have high rpm concerns. As far as clutching goes I'm way off still, but working on it. Hopefully some of this will be useful to someone.
