Z1000 MK2 Engine build. After degreasing crank I allways load up all the bearings with new oil using a syringe before building up the bottom end crankcase. Engine will be a 1075cc, bigger valves, new guide and ported/flowed, GPZ1100 UNI-TRAC cams, 34mm flatslides, Dyna ignition and coils and all new tensioner parts/wheels and 124 link heavy duty camchain.

Couple of helicoils thread repairs in a set of Zed crankcases and a Zed cylinder head. Cylinder head needed 8 cam cap threads repairing with helicoils. Decision was taken to do all 16, unfortunately one was beyond a helicoil repairs so I ended up making an ally plug and drill and tapping back to original. Used the cam cap for drilling guide. Also had to helicoil 2 cylinder studs, a bit of hassle setting up on my milling machine, awkward shape and it had to be tilted up at 10 degrees to drill out . Going on a Zed 1425cc turbo, yes that yellow one! Buzzard@thebuzzworkz

This popped up on my phone today, my USB drag bike from way back in the day. No idea where and when but that's in its final trim, 1425cc , 40mm flatslides, nitrous, lockup clutch, airshifter, raked frame and 6 inch over swinging arm. 9.5 ET at 149mph best it did. Happy days!

Haven't posted for awhile as forced to take it easy but now feel recovered enough to start a few jobs. Next two projects, a Standard Z1000J engine rebuild after engine has been blasted and painted Cerecote satin black by RVB. Engine has done 84k miles so a rebore new cam chain and tensioner and new gearbox bearings plus valve guide seals. Considering the mileage it is in good condition. Second engine vapour blasted By R D Cox back to ally finish. A 1075cc Wossner pistons, ported and oversize valves, GPZ UNI-TRAC cams , 34mm Mikuni flatslides and Dyna ignition and coils, going in a Bimota. Buzzard@thebuzzworkz

Haven't been active for awhile due to health scare but improving and feeling much better. I stripped Z1000J engine about a month ago and it wasn't a pretty sight. This is why you should never ever use RTV silicone sealer anywhere near an engine! One of the oil feed to a main bearing was blocked by a lump of the stuff, fortunately it's a roller bearing and it gets some oil splash fed from sump as crank rotates. If you must use a sealer on the gaskets I allways use "Wellseal " liquid type sealer that you brush on as thin as you can. Buzzard@thebuzzworkz

Kawasaki Z1R engine done. 1075cc , Z1000J head, GPZ1100 Uni-trac cams, 37.50mm inlet valves and 31mm exhaust valves, head was ported and flow test on my flowbench, 21% up on stock head at 0.400 lift. (Tested at 10" pressure on my Superflow 110) Head was skimmed to get compression back up to 10 to 1. Dyna 2000 ignition and coils. Will be running on some 29mm smoothbores. Buzzard@thebuzzworkz
