F3 er 650

[gammaguy]

Hate to say it but if Wobbly turns up with his RZ400 F3 bike, nothing will see which way it went. It's sitting at over 90Hp and I believe he plans to get close to 100 from what I have read/been told. All that in a bike that will be 40KG lighter, F3 just got serious.

A few years back a certain Stan Stephens built up a RZ350 engined race bike.

It was so good,all the 4T wankers got together and banned it.

As far as I am concerned,that was the best praise they could give it.

Stan Stephens still laughs about it.

Yip,

97 rwhp at its first Dyno session,Engine temp would suggest it could drop another 2 sizes on the mainjet,100rwhp easy,Still why would you bother to risk it 97 is heaps,Not convinced it will be 40kg lighter,But it probably doesn't need to be either.Weve just finished designing and producing the bodywork and its being fitted as we speak,First test was to be this Wed but the pilot hurt himself,Watch this space,Long live the two stroke

Funnily enough Wobbly does a roadbike version,In fact he has one sitting in his workshop right now.

its got the firing pulse of a 800 four stroke . should not even be allowed out in f3 ! more like super bikes ! but some people like srewing with classes to suit them selves

Who would that be then???????

Or is it people building bikes around the rules in place?

You are allowed up to 750cc air cooled four strokes in F3 anyway aren't ya?

Two valve air cooled. Appendix B 1.6 means anything with more than 2 valves per cylinder are limited to 650cc.

I can't open the fuckin PDF for some tittie fucking cock sucking reason. Does it say how many cc's though? I'm off to buy a 900ss Ducati if not, and I'm finally gonna get me a title! Those things can be coerced into producing 100+ ponies on a standard crank some spaghetti slurper reckons.
