Have you gone down 1 up front yet. I just did the accel. kit from rk on my 04 600. Little less top end(like im gonna miss it) but more torquedown low, hopefully. I really do love the overall driveabilty of my sixxer. I've taken rides on both the 1000 and 750 of the same year and it seems like I really made the right choice for once. :lol: I'm also considering a 750 swap if the chain conversion isn't enough. The 1000 I drove just made me relize how much control and focus one of those things require. Takes the fun out of it for me. I like feeling the gears and with that all u need is 2nd and 3rd. The 750 though made me think :hmmm: It would take a little getting used to but its managable for the srteet. Gonna need to ride my bike with the coversion1st to really know tho. Let me know if you go through with that swap though :thumbup:CRASH411MJ said:I'm with Vassago, I bought an '04 600 with 18 years riding experience. Plenty of power, awesome driveability. I just got a 2005 750 motor for the bike, now i'm kind of having second thoughts as to why i'm doing a swap.
