Go on then, what's wrong with a Z750 hard tail chopper then in BCF's eyes of wisdom?

I'm not here to defend, but all I'd say is:
1, if someone wants a hard tail chopper that's fine and up to them, I ain't here to judge. A lashed up period style chopper is also a million times better than a modern factory cruiser trying to get in on the look but without the full uncompromising nature of a proper hard tail built for different reasons entirely.

2, A Z750 don't handle or brake for shit in today's terms, so it's hardly like turning one into a chopper is ruining a perfectly balanced sweet handling stop on a six pence machine is it?

3, A basic and simple hard tail chopper will go and sound alot better with a decent air cooled IL4 than it ever will with a shuddering shaking lump of milwalkee iron under the fuel tank.

Sure I'd like to see something really bizarre like a GSX1300R powered hard tail chopper for the originality alone, but it won't look anything like as good as an air head engine would.

Ignoring the likelyhood that anyone on here is going to be able to guess whichever mix of wheels, sprockets and chains that such a mash-up inevitably ended up with, the only good place for a hardtail is on a stand at a show. Even harleys have suspension ffs, and they are notoriously agricultural.

Do you mean the 4 cylinder? I've got a Kawasaki workshop manual which gives specs for the different 82 models. What do you need to know? Have you still got a frame ID plate on the front headstock?

Hi yes the 4 cylinder one. Unfortunately I dint have the head stock number but do have the original V5 I also have the engine number if that helps.
Thanks

Being a chop. I'd say there is absolutely no garauntee the chain and sprockets are standard.

The front sprocket will almost certainly go with the engine but do count the teeth.

Rear, who knows? They may have used the standard wheel and spacers or they may have used a different wheel altogether and messed with the spacers and sprockets to get a good chain line.

Count the links on the chain and make sure the one you're getting is at least that length.

Regarding the rear sprocket, if you find it's not standard and you can't ID it, you can buy a blank and drill it/have it drilled using the old one as a template.

Cool cheers man. Suppose you have a link to a blank ?

Never used them. Just googled.

Part number shows chain pitch and number of teeth.

Z750 Twin cylinder JTF513 16 JTR488 530 106 LINKS
z720 FOUR CYLINDER JTF518 13 JTR501 630 88 LINKS

You may need a 530 conversion on the four as 630 chains are not very hard to source
