Repair manual for the GY6 engine
 

Hi all, does anyone know where to find a repair or service manual for the 150cc GY6 engine ? I've looked on the net and all I can find are scooter manuals ? I have this engine in my buggy and was wondering if they are the same ? Thanks in advance.

Your GY6 should be the same as all the ones they use in the scooters so this may work for you http://cgi.ebay.com/ebaymotors/Scoot...-/160354178563

Note:

Your motor will be identical to a scooter motor but for the final drive gearset.

The newest/ high performance GY6 motors have 4 valve heads, it is unlikely you will have one of those, though who knows?
