Questions on gearing changes for Chicago area tracks
Iíve been enjoying my track days lately on my K6 600 and have started putting down some decent intermediate times. This past weekend I had a buddy show up on his 05 Kawi 636 and ran around Autobahn North with me for half a day on Saturday (til he got bumped to A). I was amazed at how quick his bike was coming out of corners and just weaving around people like theyíre standing still. After some discussion, his gearing came up that heís -1/+2 which was pretty much the main difference between our modifications on our bikes. He also said when he was behind me that it seemed like my bike just wasnít running through the revs like it should (I was still in 3rd on the straight while heís into 5th). This got me wondering about changing up the gearing on my bike.
I donít need it to be out of control where Iím lifting the tire out of every corner, but was wondering if +1 or +2 in the rear might help me out with a little acceleration. As for the tracks Iím running, Iím in Chicago so stick with the Illinois (ACC), Michigan (Grattan, G-man), and Putnam down in Indy so nothing super long like Road America. Just wondering what you guys are running who see these types of tracks on a regular basis and if this is something I should be considering going forward.
Iíve heard that if you change out sprockets you should also change the chain at the same time. No problem with that as they usually come as a kit, but thereís also the option of switching to the 520 kit or whatever that is (honestly havenít looked into it). For those who have gone with the ďlightweightĒ chain, did you feel that much of a difference? Worth doing if Iím possibly going to be changing gearing anyways? I would rather have reliability with a stock type chain versus a minimal gain (butt dyno improvement) if that's the case.
