[zyrockdaddy]

my friend was driving my banshee on pavement at about 50 miles per hour. then the tires locked up and slid about 50 yards. i tried to kickstart it and the thing wouldn't move. i am not well versed in repairing these things and am not really sure what could have gone wrong. what can i do to fix it and what are some scenerios of the problem.?.?.? btw its a 95 twin350

Tried to kick it over but cant get it too move? One or both of the pistons are siezed up, in that case tear it apart look at it and see what it looks like. Also did you have it mixed to lean or have motor work done too it recently?

Also if the tranny is locked up you may have part of the broken piston down in the bottom end binding up the gears. All I can think of, maybe someone else can help you out more.

Probably not the case here. Nearly impossible for part of the piston to end up in the transmission. If it did, that whole engine is pretty much junk (the cases at least). I doubt thats the problem

 

Could be a seized piston, could be a seized transmission. More than likely it is a seized piston. Kinda need to know whether or not you could roll it after disengaging the clutch.

 

First order of business I would go for is pull clutch cover and make sure everythign is in order. Probably not where you are going to find your problem but definitely the easiest place to start. Next is to pull the head and check the pistons. If you can't see an obvious cause, pull the jugs and check the pistons, rings, jugs, crank and rods. Make sure everything rotates freely (with clutch disengaged). If you are still stumped then its time to split the cases to get to the tranny. If you are totally freaked by this, have someone give you a hand. It really isn't all that difficult, make sure you have a Clymers though, it will walk you through everything.

im guessin dude held it wide open for too long snapped the top end and a piston skirt is busted inside and hung the crank up.. my bet u need new rods and pistons,take the head off,, minimum and look,, id take the cylindars off and inspect

ok, i'm new to this end of things so this may be a dumb question but...

if tranny oil doesn't enter into the crank/cylinder area, then how would anything from the piston or anything get into the tranny? i'm concerned cuz my piston top was missing chunks and pieces of ring. i figured they blew out the exhaust if anything.

your lower end oil does not enter the crank area its only for your transmission and clutches,, your 2 stroke oil lubes your crank which there is no way for your pistons to get into your transmission,,,but i just now reread the post ... can u kick the motor over??? it might be your shift forks that are bent and holding it in gear.
