Thats why I used the sprockets and chains from the meerkat.

 

9 kids,

I have a son who will be 5 in two months. He is average size and rides a meerkat. Right now it fits him perfectly, but I know he will outgrow this quad in another year or two. I bought it used off of Ebay, and let me tell you, this little quad is great (and fast for a 50). My only gripe with it is that it's a clutchless manual and there is no stopping point for shifting. If you keep pressing the shifter down, it will cycle through all the gears and back to neutral. The same with pulling the shifter up. It makes it a little difficult to teach the young one the proper way to shift gears. Well actually, it's hard to get a 4 year old to understand how to shift anyway, but this just adds to their confusion. But it is a great quad regardless.

 

First I would like to thank everyone for their advice. I think I will be getting a couple of Mini 90’s (Roketa) from Raceway when I finish saving the money (a few more months).

For any one trying to find different size sprockets this might help.

I tried to do some research on other sources of sprockets and the only site I found that posted their Engineering drawings and specs was JT Sprockets. But you could only get to the drawings and specs by choosing a model of motorcycle or ATV and obviously the Chinese ATV’s are not listed. I noticed that all the drawings were in the same web directory. So I whipped up a quick web page that displays all their drawings on one page and a few others that just show drawings by chain size. These are just their front sprockets for now. The drawings don’t tell how many different teeth versions there are, some come in 12 through 19 teeth. If you find one that match’s your sprocket then go back to JT sprockets and look up the Model number in their Buyers Guide, it will then show you the Available teeth numbers and all the different bikes it fits. Here are the links

Hope this helps someone

 

The mini 90 is a great little quad. May have to regear but thats easy.
