Hi, want to race in FL region.I am building a hybrid with and R6 frame and RZ350 based big bore(~600cc)motor.Looking for 120HP and #300 wet weight.
I can pull off the build but am concerned about what classes I'd be eligible for and competitive bikewise .I am total noob but RD,RZ,TD,TZ stuff etc back in the late 70s early 80's.

Sounds like a nasty beast whatever it is. You must post pics of the build process.
I'd like to see the RZ cylinders at 600 cc.
I'm guessing they'd looks a lot like this: http://www.bansheedepot.com/proddetail.asp?prod=TREX7668 (http://www.bansheedepot.com/proddetail.asp?prod=TREX7668)
Especially considering the the RZ & Banshee motors are pretty similar. I had a 400cc big bore banshee once upon a time... And that thing was beast, I can't imagine what it's be like at 600+cc :ahhh:
The NSR 500 comes to mind... Just because it can be done doesn't mean it should be. LOL
Dynoed a 600 cc Banshee motor on alcohol.....175 hp.... Good luck....
Just looking for 120 hp on racegas.The Europeans have tons of RG,Aprilia etc.. hybrids with stock RZ and big bores.There are tons of tutorials and pics of the work as well as a outfit in Australia (the two
stroke shop) offering turnkey bikes.
Thanks for the info on classes daviid.
