Adjusting chains on a Max II

[mad_max_500cc]

id have to ask someone at ri to be shure but i know it was single cylender jlo engines from 69-mid 70's had the #40 axle chain with idlers. when they brought out the big max with the twin cyl engine they started to use #50 axle chain with slide adjusters. then sometime in the mid 70's they just made them all #50 axle chain.

There is more chains that need adjusted than I thought. Thought it was only the chains on the jack shaft, but i found out today that a couple of the chains are so loose that they are actually laying on the inside of the body. Wish i knew somebody that knew how to adjust all of the chains. I guess this is why i having popping noises and can't spin on a dime [/QUOTE]


I would recommend that you go with Snap Idle brand chain adjusters. They are a manually type adjusted floating tensioner, and you have to keep an eye on them after each ride. After you get some experience under your belt and start replacing things and building parts that work better, you can always make your own chain adjusters.
