Easiest way to get it ready for racing is to hang a for sale sign on it and get a 2008-2011 IQ600r. But if that's not an option then you need to get your shocks re-valved stiffer(iqr specs), gear down, clutch to higher engagement(5000 or higher) and stud it. Then(if you can run race gas) get your head cut to bump up the compression and run 110 oct to get your sled on par with the other 600cc race sleds.
I have a 1 3/4 track, i geared it down for that. You can only run 96 studs right..? The end of last year I re-valved my shocks for hill climbs that had pretty big jumps on it. And i had my clutch redone last year before i went out west and it engages at 45-4800.
Are you sure you can race stock with milled heads??
