I'm a fan of 530 DID ZVMX...other folks like the EK ZZZ chains. As long as the chain's tensile strength is at least 10k psi you should be good.

Go up one tooth on your countershaft sprocket, from oem 17 tooth to 18 tooth. It's easier on your chain and better gas mileage.
38 tooth to 40 tooth are the popular sizes for back sprockets. Get steel sprockets, not aluminum, aluminum back sprockets do not last on our FJ's.

Thanks for reporting back, mystery solved!

Cheers

 Only in the gen 4 frames ('91-95) did Yamaha offset the shock mounting needed to fit the abs pump.
Here's a list of FJ VIN's you can peruse:  https://fjowners.com/index.php?topic=13764.0

No chain difference between FJ's with ABS and non ABS FJ's
They all use a 110 link 530 chain. Get a top of the line chain for your FJ.

FJ's eat cheap chains and cheap chains beat the shit out of the engine cases when they fail.
Not if they fail......when they fail.

Speaking of which...
I wonder how MoPar Steve is doing?

Thxs so no changes in chains and sprockets. Top

The front sprocket is almost worn ...
Which chainset should I buy because I have 3CX framenumber 1988. But with ABS   imported in 1992...strenge isn't?

I want a new  chainset... but now I seem to have a problem. The framenumber starts with 3CX build 1988. But I have ABS and is imported in Europe in 1992.
Which chainset should I buy or isn't there any difference between? Thxs
