Yeah, I just spoke to him...it's just another Streety conversion so he's not bothering.

It's a 4v DOHC conversion on a 2vJawa bottom end, designed by Neil Street and built by Ivan Tighe in Bris Vegas.

A fair price at the moment and if I hadn't been off work for the past 3 months I'd be up there like the proverbial.
My first day riding a Speedway bike was actually the same day the late Billy Sanders was also testing his brand new "Streety" at Nepean late 74.
Crumpy Snr had just demolished everyone at the OZ Speedway titles, held at the Syd Showground,
All the talk from that meeting was Crumpy's engine, the 4V frienzy that followed was amazing and hard to follow. I remember wishing for a 4V Wessy Conv for my 2 Valver.
Having said that, the bike I rode was pretty much a standard 2 Valve Jawa with a "Squished" twin spark Cyl head.
I've still got the Cyl head and a few piston's, if I can get them back from big Bro.
