hmmmm find a deal on another 04/05 600(hopefully with a couple goodies) or buy a spare engine and a couple goodies or shop around this winter for deals on an exhaust, pc, quick shifter, slipper clutch and rely as my street bike as a sacraficail backup or save money to put toward more track days/racing and maybe a different/newer track bike This started because I'm paranoid about getting stuck with no motor during the season. I like my bike, I'm comfortable on it and I don't think it is limiting me. At the same time, I'd like to try something else, so investing more into this make/model doesn't really make sense.
