This is a round port 06 engine which I have refreshed bottom end with new shells to crank and big ends. Rods changed to later 471 type. Balancer shaft has had backlash ring removed. I had the head a while from Trickbits. It turns out to be an ex bsb head I think by Ray Stringer Motorsport. It has been ported and polished professionally and had a 1.2mm skim and grind. It has kit valves and I have fitted a race profile camshaft from Kent Cams. It also has secondary air delete kit and manual chain tensioner. Its had cams dialled in and head built and fitted by T3 racing. I have fitted it to a bike and had it all up and running. Sounds sweet. Have got video on my phone . I do Triumphs as a hobby and am too old to go racing again hence sale. Looking for around £1500 for it. I am based not far from Brands Hatch.
