Counter Sprocket Lock Washer?

Ordered a 530 conversion ( front and rear sprockets and chain ) set up from Z1 Ent. Apparently front sprocket has no provision for the Factory lock washer. What are you guys doing to secure front sprocket?

You probably can drill the appropriate hole for the tab using a carbide drill bit, or you might be able to use a splined lock washer like on later models (see 2001 KZ1000-P diagram below). The splined washer locks into the shaft because of the spline and then you bend part of the washer against the flat of the nut to prevent it from turning. Ed

I'd send it back and insist on a proper sprocket. They shouldn't sell parts like this. In a pinch though, if you want to use it, you can use Loctite blue thread locker on the nut. Otherwise it might be worth a try drilling a hole. I never tried it, but have a feeling if the sprocket is made without a hole, it is also made with soft steel that may drill easily.

I agree 100%. Ed

The proper sprocket would be a 630. If you are going to do the conversion to a 530 chain and sprocket set you are going to have to do a little work.
Give Z1E a call and ask if they have a solution to this problem. Be nice and I'm sure they will go out of their way to help you. Jeff has always been very good at making this sort of stuff work.

High strength lock Tight will work but to get it off, you might have to use a torch to heat it up enough to get it off.

This is what I have on my 750. See pic below from Z1 Enterprises. I had one with my 630 chain and sprockets and just put new 530 chain, sprockets, new nut and new lock washer on the bike 2 days ago. With 1 or even 2 sides of the washer bent over against the nut there is no way a loose nut can move let alone fall off. .... at least on the 750/4.

I dont know how the 1000s are supposed to be but am curious if a different setup is recommended or preferable on larger bikes

PS I dont know if the washer pictured will fit other bikes

I had to do this once, amazing how hard that sprocket is (probably surface hardened) I couldn't even scratch it with a drill. I was able to sink a hole into it using some diamond tipped cutters I got at Harbor Freight that go onto a Dremel. Took a while.....

The easy way is to get one of the splined washers that you just flatten over against the edge of the shaft nut. That's what I ended up using.

He's right.

The front sprocket was always hardened steel, but that was back when someone cared about quality and that was years ago on a KZ. Worth a try now to drill, quality is not a consideration any more. All that matters is cheap, cheaper and cheapest made in China quality

Z1 Enterprises sells JT sprockets, they are very high quality with state of the art manufacturing. I don't think you will have any luck drilling into it. Call Z1E. and ask Jeff for the fix.

I'll call them Monday. I like what JR suggested 92200-1065 Front Sprocket 13-spline Lock Washer. Too bad they didn't suggest that to me earlier. I would have purchased it then.
