Hi Wilko welcome to the site. I recently did the top end on Fishes DR 400 and had the cylinder head work done by Tekniks at Penrith. They did a good job to the head, did the valves and got all the gaskets etc I needed to put it back together. Being a OBT sponsor Fish got a discount.
Tekniks logo scrolls across the top of all pages here, click on it for contact details tell them your a member and TB sent you
How about going to the intro section and doing an intro, tell us about you, where you ride etc
