Cr 500 supermoto/roadrace

I was considering this as well....never did it though. I ran into all of this same conversation. lol

 

I got back from road racing my cr500 at Roebling Road in Georgia and Daytona. I live in MT so the trip was long. I've done some more performance modifications on my bike. Here's whats been done:

Extensive port work
Falicon crank
Ty rod
Remote starter ( you're not kicking over this baby)
Vortex 10 map ignition (Red line 9500)
Knology coil
Hand built Jemco pipe
Bored Carb
No air box
Back cut tranny gears
Barnett Clutch
Carbon Fiber Reeds
16 tooth front sprocket (hand made)
36 tooth rear sprocket (Rebel Gears made it)
Cut Down Radiator shrouds
Buell Fly Screen
Hand Made Seat
And some truly secret head mods which smooths out the vibes!

Results:
79 rear wheel horsepower
Speed trapped at 132 mph @ Daytona (passed sv 650's and Ducati 900's on the banking at Daytona)
Led every lap at Georgia against a multi time national champ on a factory prepped KTM 660
Was winning @ Daytona until bad vibration caused me to pull in. Upper motor mount came loose. DAMN!

Even with all these mods my bike is truly reliable. A lot of this though depends on how you ride the bike. Coasting kills two strokes. Hold the throttle on until the last minute. Than slowly get on the gas prior to the apex of the turn. More gas means more lubricating! Lubrication saves motors. I never run anything less than 110 octane and I always mix it 20:1

 

^ That is one serious machine. Sorry about the DNF, but you'll get those diesels next time!

 

hi guys, this an interesting post

I also have a highly tunned cr 500 still with the old steel frame. I am thinking about putting this engine (70 hp at the rear) in a CRF or CR 250 2004 frame

 

what i would tell you to do is get an older trx250r motor (counter balanced) and get an esr 440 (i think) pv kit and put that in the cr500 with a 4mm stroker it would be a little over 500cc but would vibe near as bad

 

here is a better Idea .. take a RZ 350 motor put in a Aprillia RS250 roller. before you install the RZ have it send to TSS http://www.twostrokeshop.com/
have them build you a REAL 2stroke motor.. install , ride it like a young Mamola..
