Member Ricky Racer, he's Classic Cycle City in the USA, he sells them, if you are in Europe try member Nippon, he's Classic city in Germany, you've also got CycleX in the USA they have a similar Heavy duty chain but with small holes in the rollers for a supposed better lubrication, I have the original ones from Classic Cycle city {without those holes} and don't see any need for the ones with the holes...

I ordered mine from Classic Cycle City in Germany. My engine runs now with less rattle. I think they are a little bit tighter than OEM.
I need better rods to match the chains, then bigger pistons to match the rods. Undercutted gears to match all these stuff together  ;D

I just put a set of the Cycle X chains in my drag motor,  dont have any time on them yet though.  Will see how they hold up.  They look good though.

Are the CycleX 'rollers' actually rollers or are they stationary hence the oil holes?

I could be wrong but i think the cyclex chains are the same as the classic cycle city chains, just with the oiling holes driller in the rollers...?

EDIT
I was wrong, completely different chains....
