Broken piston skirt

[banshee_boy09]

Ive got an 01 banshee and the piston skirt on the intake side of a 65mm pro lite broke off, I guess im lucky it didnt do more damage then it did. But any advice would be greatly appreciated.

Build it back, keep it tight, no problems.

it could be caused by a couple of things. One the piston colapsed and was loose in the sleeve, or the exhaust port is too wide allowing the piston to rock putting pressure on the skirt. Or over revving the bike. I have had three pistons do this and cant nail down exactly what the cause is. Are the piston windows opened up? Some will say that causes it also but I still cut mine. Hope this helps

I would make sure to check for pieces around the crank before you jack it up too. When that happened to my piston the pieces fell down and jacked my crank up sucked. Now go get ya some wisecos.

taking off too many times on a cold motor can do this too, but excess clearance is the number one cause, unless you windowed the pistons.
