Big bore hawk motor?
I've been doing some research on the motor used in the Hawk ( Apollo, Tao Tao, tt250 etc ) for a big bore kit and have read lots of threads. This is what I found. There is no big bore kit ....BUT.... you can buy a replacement pistons in just 2 oversized dimensions... 67.25 mm and a 67.50mm.
I have not found matching cylinders. So if you buy an oversized piston, you can have your cylinder bored to match. This does make the cylinder wall pretty thin and using an external oil cooler would be highly recommend Just take into mind, boring out a cylinder cost more the a new stock cylinder. ( 38$ for stock cylinder ) So if you want to get the most disposable displacement from your engine, that's the best I've found. |
