Well after Robspeed Motorcycles at Grimsby serviced Blue Rex and left it misfiring within 3 miles of their workshops, I decided the time had come for Blue Rex to get some fettling and proper setting up.
I’d been keeping a set of cams I’d been sold a few years ago which I was told were ZZR1200 cams. So I rang Larry Webb at PDQ in Berkshire to ask him what he suggested. He recommended fitting those cams, gas-flowing the cylinder head, fitting high compression pistons (in the existing bore sizes) and then fettling it all together properly, so I dropped it off and have left them to it.
Bad news came recently: the cams I’d been sold were actually standard ZRX1200R cams so I now have the existing ones plus a set of new ones. Larry is going to send them to the States to get them re-profiled instead as that’s what they used to do back in the day. This will add a few hundred pounds more to the existing quote, but is cheaper than buying new ZZR1200 cams which are silly expensive.
We’ll see what results we get.
