Just started doing a lot of looking into getting the coolster running again and I seen a reference to them having a GY6 engine. I see a ton of info on that engine on the web but can not find anything that says the 125cc is definately a GY6 motor.

Lastly if it is will most any GY6 component fit on it. Or did they modify it enough that you have to use Coolster parts?

 

Gy6 engines have a distinct look, as well as having a belt driven Continuously Variable Transmission (CVT).

Look for a horizontal engine topology, with the cylinder cooling fins shrouded in black plastic (part of a forced air cooling system). Google GY6 engines to see what I mean.

 

If this worked this is the engine that is in it. I tried using the above gy6 identifier but the numbers on the motor do not match up to them. That did not work so here is a link to the engine in it. http://www.ridemaxdealer.com/index.php/main_page/product_info/cPath/21_88/products_id/15904

 

I couldn't get your link to work for me without futzing around with it. Is this the link to your engine you were talking about?

125cc 4-stroke Engine with Semi-Auto Transmission w/Reverse, Electric Start for ATVs [308-999021]

If so that is definately not a GY6 engine. It looks more like an E22 style engine.

 

Yes that is what I have. Thanks After looking at a few things I did not think it was a GY6 but wanted to make sure.
