Whats The Full Scoop On The Rz

Recommended Posts

I some of you modding up the banshee with parts from the rz. Is there a benefit on using rz parts? What about the motor, is there something special about the motor that is beneficial to it versus banshee components?

 

I wasn't very old when the rz was around and I don't know much about it, just wanting to try to learn a little more about the pluses and minuses.

First off, try a search for RZ there's already tons of stuff on the HQ about it.

In short the RZ engine has the same block as the banshee so it bolts right in. It has a larger head and cooling jackets on the jugs. They also have power valves so the stock HP of the Banshee goes from 37 to 55 for the RZ. That's 50% more HP. The tranny has better shift forks and the ratios are a little different so you can swap 'em out with banshee gears to fine tune your gearing. The third advantage is that if you are looking for a complete engine, they are usually a little cheaper on ebay than banshee engines.

Draw backs... you have to run a battery to operate the power valves as well as the CDI and stator and wiring can be a little difficult you also need a special fitting to convert to Banshee pipes. All in all if you're handy, it's a pretty easy transplant.

This raises a question for me... I used to have a 1973-4 Yamaha 350 air cooled 2 stroke street bike. I know this isnt the same bike in question here but did I FU(K up by giving it away? I had a nasty wreck on it and just gave it away..This was about 10-12 years ago. I have always wondered what relation that engine was to the shees... :unsure:

ive been learning bout the rz too while doing a conversion.....their shift forks are much better than a shee, they have these roller bearing things i think they call it....direct replacement to the shees..allows smoother shifting

 

also when doing the conversion its not a straight transplant......flywheel, cdi, stator...wiring and abunch of electronics to control those valves need installed...and all from the same year....

 

the rz is a great race bike with that almost shee motor.......

The RD of the 70's and early 80's was not quite the RZ {also called RD outside the US}. You see 'em come up on ebay every once in a while. Don't lose too much sleep over it. I sold my 1984 ATC250R for $75 and I passed up a 66 Hemi Charger for $2500. Now THAT is STUPID :wacko:
