Hi all.
I live in Cheshire, who is the best tuners to fit a oil cooler and gas flow my cylinder head?
Thanks for any info.

Chris at Grumpy1260 rebuilt the motor for my 1000SZ, but I have yet to run it
He can also supply the cooler, hoses, adaptor and bracket.

One my friends took the 750 donkey from my Kat and Chris rebuilt the bottom end for him. It’s been thrashed, as an 816, round many racetracks and is still going strong.
Victor Four, aka Jonty, has had some work done to his Kat (and possibly his Yamaha Turbo) by Chris

Peter Stansfield has a good reputation, but other than buying a set of barrels and pistons for the aforementioned Kat I haven’t used his services.

Another person to try would be Roger Upperton. I think he is up your way.
