I just installed mine and while everything is on and ok. Sure seems to hang out the back a long ways. Really doesn't look like it can go on any other way though. I'd like to see some pics of the IDS2 on someone elses 650L Also, I just put the stock set of disks in. Sure doesn't seem like enough flow area for a big 650. I think I'll buy another pack of disks and get it up to at least 10 or so. I've done all the other requisit mods, (smog pump, 14/48 sprockets, D606 tires, Uni filter, moded air box, moded seat, 58 pilot, 155 main, drilled slide, raised needle, removed ALL unnecessary stuff). I haven't had it on the road yet to see the effect on jetting. I had the stock pipe insert out so I'd guess that with the stock disk set (7 or 8 I believe) it should be jetted pretty well. I'd assume that if I up the disks to 10 or so I might have to up the main jet. Any input on the number of disks I should run?
