Tighe Dohc 4V

[Dutch]

Here is a pic from according to the info, from a Tighe Jawa. Are there members that know the difference between a Tighe and a SR4 conversion.

any pics of the other side Dutch ?

Tighe and Street worked together on the first model and from the pic that is the same. Later models followed including a rotary valve version. The Street conversion is sometimes confused with the ERM 4V Jawa conversion which preceded it.

Here is a pic from the other side.

TTezza I have the pics from a friend and they are taken at a speedwaybike show in New Zealand.

GD66, Do you have more information from the SR4 with rotating valve.

[TTezza]

I will ask the mate for more info, I know the motor was raced by Bob Valentine in England before he got onto a Weslake

I don't Dutch, and have launched out a heeeap of mags when I moved house a few years back. Ivan is gone a few years ago, but Tighe Engineering is still running in Brisbane and his son Dean may be of assistance. Think it's Tighe Cams these days. I recall the hoo-ha when it was revealed, but I don't think they put much time or money into any subsequent development.
