Low hole piston not high hole.
Worked perfect with dioreed and racing carb high compression head and BBR tuning thrust exhaust. Although I had a China expansion chamber that gave me better all around better torque it had a pin hole on the weld. So back to the F2 thrust exhaust which is the loudest exhaust by far you can buy. Overall this piston has been working well as long as you set the squish properly you'll love it. Won't work without reed valve and tuned carb with proper jets and fore mentioned performance parts. With a 36t sprocket I'm at about 45mph top speed. Might I mention I weigh about 250lbs. Also the BBR bottom end has been an awesome bottom to build off of.

Wrong wrong wrong
Should have listened to the reviews!!!!! Most kits are short hole pistons and this isn’t!! Don’t know why they even sell this piece of crap!! It’s junk .. DONT DO IT!!!!!

Great piston for the price!
Good machining on my piston I received! Definitely a lot better then trying to do it myself! I also needed to change my piston bearing and it had little to no play once installed!!

Product did match description
I ordered this piston for my bike it says it's a high hole piston when it's actually a low hole piston making it unusable for me definitely a waste of time and money

Made no difference in power at all
I purchased this in hopes to gain power after adding a read valve kit I honestly feel like it didn't make any difference at all if anything it seems more sluggish on takeoff and it seems to take longer to find a smooth Power Band the idea of the window piston on paper seems like a logical power adder but after running it not impressed feel like i wasted 30 bucks

Manufacture error
Hi I Received my order today I installed the piston and rings on my 66cc /80cc long connecting rod is the reason I bought this to find that the piston is coming out the top about a quarter inch to much,, hitting the Cylinder head, I believe the Rest pin hole is to far down on the piston Manufacture error
