AK Redline

I dont know why or how, but my piston skirt broke off the left piston and fell down into the crank. resulting in a locked motor, the piece was wedged in the crank and locked it up and their is other debris that i think got down into the case. So me n my buddy are gonna have to rip that open and clean the case and MAYBE replace the crank... but while its apart id do some mods.... so ive come to that im gonna put wiseco prolites in and itll have to be bored 40 or 50 over since the ugly pistons scarred the cylinder really bad. im gonna do a cool head, and im gonna port and polish, and my buddy is giving me is olf fattys. With these new mods and my lack of money for bigger carbs... could i get away with boring my carbs out? and with these new mods would it be bad to use the stock clutch? or would i need a new clutch to cope with the power increase. thanks for an input my banshee is goin from stock to this so it should be woken up! i cant wait

ok the one day i tried starting my banshee and it started and died... then the kick starter locked up.... ok so i seized the motor... no big deal well a few months later like tonite me n my buddy rip the motor out and he takes it to his place and pulls the cylinder off and my piston is melted and about an inch and a quarter are missing from the one. ok so i need new pistons no biggie, NOW they took the bottom end of the motor and flipped it upside down and shook it to get some of the derbis out of there... and rocks fell out... yes rocks. dont ask me how they got in there but my bottom end it very dirty and not good... and i think im gonna need a new crank so this one aint gonna be cheap... i figured id post that since i was kinda blown away that rocks were in my motor.... haha oh well time to riop it open and start modding.
