Hey all I just bought a 89 GS500 track bike

Motor:
-2mm overbore
-hi-comp pistons
-custom Rich Omdahl head: extensive porting, combustion chamber work, Alum/silicon/bronze valve seats, shim under bucket conversion
-1mm oversize intake valves
-oversize cylinder head studs to allow for higher head bolt torque(less head gasket leaks)
-full race cams
-oversize Keihin CR special carbs w/ K&N pod filters
-counterbalancer still installed
-Yosh short baffle exhaust
-Dyna 2-stage rev limiter (hi-limit plus launch limit controlled with clutch lever)

Suspension:
-Fox rear shock w/ remote reservoir
-02 GSXR600 Front fork, revalved and re-sprung for 200# by Matt Prentice this year
-Double disc brakes up front w/ TL1000 master cylinder

Bodywork:
-Ducati 999 Upper and Lower
-GSXR front fender
-Carbon fiber TZ250 tail section w/ custom aluminum sub-frame
-Woodcraft rearsets

I think this will be a fun bike to track

Even though I'm new at MNSBR, I thought your username looked familiar.  Welcome to GStwin :cheers:  There's a few guys with race bikes around here that seem to know a lot; The first few that come to mind are werase, dgyver, D-day, and JamesG(currently in Iraq) and I know I missed a few others.  Sounds like the bike you picked up has a pretty good setup too, hopefully they guys here can fill you in on everything else you need to know.  I may know one or two things too :dunno_white:

Do you know anything about the Dyna 2-stage rev limiter? I'm building a race/street bike with 79mm pistons (555cc), high lift cams, upgraded valve springs and a bunch of other goodies. From what I know the closest thing the GS has to a rev limiter is crappy valve springs, so when I upgrade them I could get myself into some hot water. If you have any info on the rev limiter used on your bike it would be greatly appreciated.

I know very little about the bike honestly but as soon as it warms up I can get you the model number.
