15 front 35 rear sprocket 630 chain, actually converts to 18 front and 42 teeth rear sprocket 530 chain x 110 links long.

I have a valve refacing machine if your valves need a reface, I also have the 3 angles of valve seat cutters if your cylinder head needs the seats re-cut, but before doing anything I would check the valve guides for any play and also I'd check the valve stem diameters for any possible wear, there's ...

Nothing to add to what zed1015 has posted, obviously been their and done it before, but with a bit of machining work it not hard to fit any of these heads, you've just got to decide what you want to do with the motor. Buzzard.

First off I would'nt go as big as 1460cc, not alot of base gasket left, 1325cc .@ 10.5CR is perfect, cams selection, Andrews 3X, 0.418 lift good duration and you can still use shim on top, pit stop performance are now making these again, PSP 3X I think.GPZ1100 cylinder head is a must as you can go m...

Londonz1, I was just wondering what BLR were like as I have a machining job I can't do myself so it was a general enquiry, are they ok to deal with. Buzzard.

Don't need a torque arm, the bracket arm has a slot machined into it and that engages with a spigot on the swinging arm which stops it from rotating when brake is applied. See first picture with wheel in it. Buzzard.

Already got a Z1R TC, Peterf is taking his along with Stuart Pennys September 72 Z1's, van sorted, Premier Inn booked. Buzzard.

In the picture of all the caps connected with the busbars are the two vertical banks of caps connected the right way to the horizontal banks of caps, or am I missing something here? Buzzard.

I looked at those but there was no info so I didn't both, you've had a right result there. Very similar to Andrews 3X cams, a good size cam and you can still run shim on top. Buzzard.

What we need on this website is the ability to put pictures straight off your smart phone directly on to the forum. I can download pictures straight onto Facebook from my gallery, when is the website going to be updated now we don't get a mag any more? I want to put more pics on the site but it need...

Well done that man, what you making? I'll put up some more pics of other stuff I'm making but I have to go via my mate panzer John coz that photo bucket lark is to complex for a thicko like me. Buzzard.

Bike is looking good, look forward to seeing it run. Are you running a separate oil scavenge system for the turbo? Buzzard.

Mr F, have you still got that jumper? Buzzard.

6" wheel centrally fitted in frame/ swinging arm, didn't need to offset wheel or widen frame or move engine, but using 5/8" offset sprocket and still got 10mm chain to rim clearence and that was with a 630 chain. Buzzard.
