NA-40002 Standard Piston Kit for Yamaha Blaster HI

though it would have been better for the pistons to be listed as having advanced exhaust timing over the standard piston,if you weren't after this you would be disappointed

I bought this piston and have my first 25 hours after the break in. So far doing great. I went to the nomura site and watched a video of a girl beating these pistons with a hammer on a cement block so not as cheap and fragile as some people say. Worth buying for sure

DO NOT BUY THIS UNLESS YOU WANT TO DESTROY YOUR ENGINE. It shattered in my engine destroying it. i installed it correctly and did not push it too hard and it blew up. DO NOT BUY.

Bought one of these less than a month ago got it on time and everything and ran great just as half the reviews said, however also as the other half of the reviews said it only last a few weeks and then it blows up destroying your top end!

So happy to find parts for this older quad! I appreciate being able to find the parts at a cheap price.

This thing is a P.O.S I put in my blaster recently and it broke

was not worth anything that we payed for it and no refunds
