Chain adjuster coolster 3150dx2

[zackattack91]

I can't find how to adjust the chain on my 150cc coolster. Anyone know where and how it's done? Thanks guys

Also, I can only find one grounded wire behind the voltage regulator bolt. Shouldn't there be another one somewhere? Anybody know where it is?

Based on the pictures I've seen, the adjustment looks the same as my Rhino. Between the rear sprocket and disk brake, there are two, double nutted bolts at the bottom, rear of the swing arm. These are the left and right adjusters. They look like eye bolts. To the sides of these, there are four bolts, one on top, one on bottom, two each side. Mine are 19mm. These tighten everything up after the adjustments are made.

Here's how to adjust the chain;

Loosen and take off the end nuts off the adjusters.
Loosen the remaining adjuster nuts.
Loosen the four bolts...everything is sloppy at this point.
Loosen or tighten the adjuster nuts to adjust and align the chain. Start with both adjustment nuts at the same location on both adjusters to see if it looks aligned. I measure them with calipers from the nut to the end of the adjuster and make them equal.
After everything is adjusted and aligned, thread on the second lock nuts on to the adjusters and tighten the nuts to each other to keep everything in place.
Tighten up the 19 mm bolts, snugging each up a little at a time until all are tight.

Find a way to pull the chain tensioner out of the way through this process as it throws the measurement out of wack.

Everything he said except the chain tensioner part. The coolster doesn't have one. Also, the DX2 comes new with the chain way too tight.

Below is a picture of the rear of the Coolster according to Google. Looking at the bottom, middle of the picture you can see both adjusters.
