Just won the bid for some rz cylinders off of ebay and they're headed to my house. I'm hoping to have them completely rebuilt, powervalves and all and have them ready to put on my banshee when it needs the top end rebuilt. Anybody else have rz cylinders on theirs?

 

what else are u going to mod on it?

 

I plan on the cylinders, a different head(higher compression), probably just oversized pistons to match the cyl, toomey t5s, filter and rejet it, and maybe ever bigger carbs if I need the extra fuel and air for the power levels.

 

I really don't know what kind of power levels I'm looking at with all that stuff.

 

it's not going to get the most out of it... what riding are you going to be doin with it?

 

what are RZ 350 cylinders? Isnt the 350 the stock bore?

 

rz 350 cylinders are a powervalved version of the banshee ones..which is great.. especially for trail riding and flat track

 

Powervalved?

 

yes.. basically it changes the size of the exhaust port giving you better throttle response and a more power on demand.. along with a wider, smoother powerband

 

isnt changing the size of the Exhaust port basically called porting?
