Hi Guys, just acquired a z900rs rear light for my z thou special, just wondering if anyone knows where I can buy a plug to fit, without having to butcher a wiring loom. Thanks, Mick

Sent you a pm

I think the wiseco pistons are 10.5:1 compression ratio, yes I am using uprated studs and nuts. Hopefully some knowledgeable person will set is straight regarding gaskets etc

Hi Guys, after some advice. I have bought a wiseco 1200 kit for my z thou special. I have an unnamed big block which I could use, or bore out a set of standard z1000 barrels to suit the oversized liners with the kit. Are there any downsides to running a big block on a road bike? Also, the last big b...

Hi Rob, is a Z1r crankshaft the same as a Z1 crankshaft, or same as Z1000A1? The reason I ask is, I have a Z1 crankshaft, which I haven't pulled apart yet and was hoping to find another the same so I can build one good one out of the two. I am interested though, cheers, Mick

Thanks for the info, I don't need the big end or crank bearings as I removed the old bearing rollers and fitted new rollers into the cages, I mentioned this in case anyone else is looking to replace theirs. Still wanting a clean crankshaft or any good parts, thanks, Mick

Still looking for a rust free crankshaft with minimal wear if anyone has anything, also the outer bushes or races with no pitting, anything useful, even damaged. I now have a supply of high quality German needle rollers to refurbish the outer crankshaft bearings if anyone is needing them. I can pres...

I have now bought a pair from J Browse

Whatever they go in, they will need oversize liners, pistons are 78mm, not 73mm.

Hi Rob, yes I had seen them on the net, I thought the rods and roller bearings were available to buy, I hadn't realised they were only available as part of the rebuild service. I did consider buying a new crankshaft from cmnsl, but they don't seem to be available, the outer bearings and races seem u...

I am interested to know if anyone in Zed land has done their own crankshaft rebuild? I have just stripped one down to get a feel for what's involved, it's no use as it has rust on big end journals and the outboard ends. I have a good crankshaft that I aim to rebuild and weld as it goes together. I c...

Thanks Al

Guys, looking for a set of 83-85 unitrack cams in good order, if anyone has a spare set. Thanks

Thank you both for your help. I thought I had read something about the base circle being smaller on the later ones, the info is invaluable, cheers Mick

Guys, looking for camshaft advice. Cylinder head is a z1000j with camchain adapter on z900 bottom end with 1075 wiseco pistons. Are the later cams, Z1000j/gpz1100 type a smaller base circle than the early type? I am looking for general advice on which cams to run in this head, I was planning on usin...
