There are many types of the SR4 conversion made by Neil Street.
For Jawa the MK1 / MK2 / MK3, but I found also some information from SR4 conversions for JAP and COLE engines.
Recently Ivan Mauger was in the Netherlands and he visited the Dutch Speedway and Grasstrack Museum.
I was there also and could ask Ivan Mauger something about the engines and bikes he used.
He told me that the Street Conversion is very different then the Ivan Tighe Conversion.
The big difference between the 2 is that the Ivan Tighe have a much steeper inlet track, and the camchain cover is with many small bolts, to make it almost dust proof.
I never seen these Ivan Tighe conversion, so I am looking for information.

Is this the Ivan Tighe conversion (looking at the many small bolt in camchain cover) or is it just a normal Neil Street SR4 conversion
-
I may be wrong but I'm pretty sure it's an Ivan, Mauger, on the bike and he's sitting on an early Streety.
-
i thought that may have been Phil Crump on the bike
-
I remember Ivan riding one and I don't think Phill rode for Exeter.
Check out his left hip, looks like Ivan to me?
Is that a Kiwi flag on his breast plate?
-
Looks like the Southern cross.
-
It's Mauger, there's a pic of him on his Wiki profile in a similar set of TT leathers, with Exeter on the leg, Ivan on the hip and even the Renolds sticker on his forks. On re-reading his career achievements, it's still a staggering list... :o
-
Don't forget that the Kiwi's live under the southern cross as well.
Our stars are white only and the Kiwis has one less star and red in their centre.
You're right GD, his achievements are amazing.
That shot may have even been taken at the World Final, check out the crowd in the background.

The rider is Ivan Mauger, but what is the conversion.
-
Sorry for drifting away from your original question Dutch.
I can't tell you which conversion he is on.

Found another pic from the Ivan Mauger bike with the mystery Dohc 4V head.

On part one of Mauger's own website, it says "Neil Street would not sell his conversions to me as he thought I would take it to Jawa to copy. So I contacted Ivan Tighe in Brisbane who helped Streety to make them in the first place. My Engines were not Streetys. They were made by Ivan Tighe in Brisbane. Ivan told me to send an engine to him and he would do it. I sent him an 890 Speedway engine and an 892 Longtrack engine. Couple of weeks later he sent them back." etc etc...
There is also a shot of him sitting on one when collecting his MBE, but although the pic is taken from the rhs, you can still make out the shape of the valve drive train. Thanks for the bump, I enjoyed sifting through all the speedway stuff ! ;)
