After reading through some RZ 250/350 stuff would the 350 barrels be an option and if so what about Yamaha Banshee and all there replacment barrels i.e. Cheetah barrals as sold by people like www.trinityracing.com

Karl,<p>The RZ/Banshee barrel has several things wrong in terms of it being fitted to the RZ500 case.<p>1. The bolt pattern is off on all 4 studs.<p>2. The stroke is 54mm necessitating a stroked crank or machining 4mm off the bottom of the cylinder to get the stroke to proper level not to mention then having to port it again to get the timing back or near what you'ed need for good performance.<p>The monoblock Banshee cylinders will NOT work simply because the spacing of the cranks center to center of rod is wider on the RZ500 than the 350 base engines.<p>Regards,<br>Bill Wilson<br>Wilson Perfomrance<br>Lee's Summit, MO<br>Member RZ500 Owners Group #573
