I have a 98 Mojave and a service manual that covers 87-95 Mojos. I checked the chain slack and I'm at the upper end of the 40-50mm usable range. I also did the 20 link length test and it's coming in at 318-319mm. I guess the eccentric chain tension adjustment only goes so far then it starts to become loose so ya gotta back it up a hair to keep it in the maximum tightness range. Any how in the manual for 87-95s it calls for a DAIDO,Enless D.I.D. 520 VC.5
90 Link chain and in the back it has a supplement for 88-89 Mojos and calls for a ENUMA Joint Endless, EK520 SR-02 90 Link chain. I was wondering what do all these name & #s mean? And what is the correct chain for my 98 Mojave? I guess I'm suppose to replace the sprockets now as well and keep the others in my toolbox for emergency field repairs! Factory or aftermarket parts suggestions as well!

I'm not sure what all the numbers are for but your 98 should call for a 520 o-ring chain, that's what my 2000 is supposed to have. I recently went with a "regular" 520 chain and saved about $30 and it works fine.
