Questions & Answers

Is it possible to use this with a Mini Z?

A mini-game, as far as I'm aware, is a small piece of software that can be used to The car z is controlled by a remote. br>This item is a lot bigger than it needs to be. More for a small dirt bike's chain tensioner.

Are the rollers' inside holes 1/2 inch in diameter?

In reality, the hole is 15mm in diameter or 0. 5905512 inches is the length of a piece of paper. A little more than a half inch in diameter. If you're going to use a bolt, I'd recommend sticking with the metric size to ensure a good fit.

What's the best place to get a 15mm bolt to put it in?

Metric bolts and nuts are available at most hardware stores; I purchased mine at Tractor Supply, but I believe they are also available at Ace Hardware.

Is this going to work with the Mountopz Coolster 125?

I'm not sure. We bought it with the intention of retrofitting it. Adapt a bike to include a motor. Sorry!

There are no bearings here
5/5

Fits the Coleman CT200U Mini Bike but not the Coleman CT200U Mini Bike.

Coleman mini bikes are not suitable for use
3/5

The bracket hits the torque converter on the Coleman CT-200u mini bike, so it will not fit.

On esrth, a lazy company and a lazy product equals a waste of resources
3/5

Is NOY a heavy-duty vehicle? Don’t buy this tensioner,’s 100% weaker than the one you are trying to replace, guarantee it’s 100% weaker than the one you are trying to replace, garun The spring is basically a feather trying to hold up a brick, so it will not keep tension on your chain. It irritates me greatly that there are companies out there wasting resources by producing inferior goods. TAKE THE EXTRA TIME TO PROVIDE US WITH A GOOD SPRING. People are literally purchasing these and discarding them. What a waste of time,.

Chain tensioning is simple to set up
5/5

The chain tensioner was installed in a way that I liked - I had to use a different spring, though. I was specifically looking for the arm and roller - Despite this, the unit appears to function properly and maintains spring tension as specified by the manufacturer. The plastic roller's durability will be determined over time. And since the seller only sends two rollers, I'm guessing they won't last very long. Installing a sprocket onto the shaft of the tensioner is an easy fix if the rollers do not last.

I installed one on my Baja minibike and it works flawlessly! Yes, I had to make some minor adjustments to Frank and the tensioner, but I couldn't have asked for a better fit
5/5

Since installing the bike, I've put quite a few miles on it, and it shows no signs of wear. My only concern is that removing the nylon wheel appears to be impossible because the rod spins when torque is applied. br>br>I've already ordered another one for the next minibike. br>br>My only concern is that removing the nylon wheel appears to be impossible because the rod spins when torque is applied. br>br> Because the wear is minor, it is only a minor concern. It is unlikely that I will change it anytime soon.

It gives the impression that the bike is broken
3/5

It's effective, but it's not perfect. When I drive too fast, it makes a rattling noise as it jumps up and down, making a ringing noise.

I like the Chain tensioner, but it's a little difficult to find a bolt that big because of the large mount hole
3/5

To mount it to a minibike I was working on, I had to think outside the box. If it had a mounting bolt or bushing to size down the hole, I would gladly pay a higher price. 3 stars. That's all I have to say about it.

A bushing should be included
3/5

There is a missing part: you will need a 15mm to 12mm bushing to fit a 1/2 inch bolt; otherwise, you will have a difficult time finding a 15mm bolt to install! I spent a long time looking for a bolt that would fit this perfectly.
