Did a local machinist do that work for yourself, Willys? Or was that sprocket made for a customer of yours?

I had kind of wondered how else one might make a degreeable camshaft sprocket for the KLR engine, other than WymanWinns set-up.

I made them myself, made 8 I believe and sold them all.....no complaints or come backs so they are hopefully still running all over hell's half acre....lol. They are adjustable to 1 degree so you an choose whatever advance up to a full tooth jump. I may still have one here somewhere but I do not think so. I made them on my machist's mill one afternoon. Simple when you have the right tools. Marking them was the longest part of the job....lol.

Nice job! How much did each sprocket sell for? Maybe this thread will generate some more biz for you.


That (Hell's Half Acre) is some fairly other worldly, rough terrain!

Hell's Half Acre, Wyoming, Image Search | Ask.com

The area was used for the movie "Starship Troopers". Visitor center and out-buildings are gone now.
Hopefully the owners took the movie money and Ran! With older, slower, rougher, noisier, hotter cars (no AC) people used to stop more often and longer at these little tourist traps.

I sold them basically for a loss to get people's attention but it seemed that people were more interested in the Mike's full tooth jump. But now they have realized that only the Gen II engines really benefit from that much of a jump. IF people want them I will start making them for sure, but at a profit this time...lol. Each sprocket takes maybe an hour of my time if you working out making 6 or so and dividing the overall time out. Plus i need to give some for the use of the mill and tooling. So like I said I did it at a loss just to see. I knew they would work it was already proven by Cary and also Wyman.....I just hated the way Wyman's were made with those small inserts.....they just didn't sit well with my way of worrying...lol. Mine are simple repositioned pin locations with simple markings to show which hole to use. I do not think anyone used any of the other pin locations except 4 or 5 degree positions. Also I never heard of anyone selling them or asking for their money back if they didn't work, so I'm assuming they are still running them.
Again IF half a dozen people want them made I will do another run....the last one's I think I sold for $50 or $60 a sprocket. The other issue is I need sprockets to work with, something I do not have at the moment.
Do I think there is a market for them, sure if you are after the best from your motor IF you are not going to buy expensive cams. The expensive cams will have this advance built into them, or at least mine do from Mega Cycle cams do. That is the only reason I am not running them.
I hope this stupidily long post answers you questions.lol
