BANSHEE PLEASE REPLY SOON

well i had a warm day so i started taking the banshee apart today. i was draining the coolant (what a mess! coolant all over my pants. why do the drains have to be on the side of the cylenders?!) when i had all the coolNT DRained there was only about a quart drained out (not counting what got all over my pants and the floor) the radiator was empty, the over flow however wasnt. a vast majority of what drained out came out of the right side, barely any came from the left side, coincidentaly the left side is the side that has barley any compression. now each side should be effected by the other draining because they are separate right? and the same about should be in each jug correct? so then why was barley any in the left side? she did go up in a bunch of white smoke when she blew so im thinking the head gasket on the left blew and blew a bunch of the fluid in the jug with it. make sense? anyhow im going to rip the engine apart tomorrow to see whats up. what should i look for/check/do when im taking it apart?

another question...my dad thinks that i should use "gasket in a tube" which is some goop that is used instead of a gasket. now i have never heard of anything like this being used on a 2 stroke atv, always just heard of normal gaskets being used..so what is the answer to this??

thanks for all the help guys! im thinking while im rebuilding it i might as well sink a grand in parts into it and make it nice right?

I think you hit the nail on the head. Since one side may have a blown head gasket, less coolant drained out.

Use a factory head gasket if you have a factory head.

Once you get it reassembled, check for cylinder leak down PSI. If your seals on the bottom end are shot, your engine will run lean, and blow a top end again. I know cuz it happened to me repeatedly.

Re: BANSHEE PLEASE REPLY SOON

ok i took the head of today and the cylenders and pistons looked fine the cylender walls wernt scrathed or scoared and the pistons didnt have holes in em or anything. however the head on the left side was all pitted and gross looking. so i took it to my dealer and asked him about it and he said that it looked like it ate a ring at one time but it looked like it had been polished out and that it wouldnt affect anything. so is he right?

also if the head gasket was bad how would i tell? there didnt look like any places when stuff could be blowing out. the whole thing was just all black. now it it isnt the head gasket anfd the engine looked fine that has to mean it just needs new rings right? the number stamped on the pistons was 69 so these are mother effing big pistons. is it gonna be hard to find rings for these? thanks.

In reguards to your pistons being of the size 69 that stands for the mm, if im not mistaken ur shee has been bored .40 over. Its shouldn't be hard to find the rings for them. I know for sure the dennis kirk will have them and sell for about $32 www.denniskirk.com

Ive pitted 3 different stock heads on my ol Banshee. They are about $140 from the local dealer, then i went to PD head.

I would get another head, stock or aftermarket, to avoid pre detonation. I havent seen the head, but little nibbles of metal will ignite at the wrong time and make it run hot.

Those are HUGE pistons. Stock is 64mm. I know that once i put .060" pistons in mine, it always overheated, despite the Toomey rad, PD stainless pump, Cool head.

Contact Wiseco for rings, or a distributor of them.

Re: BANSHEE PLEASE REPLY SOON

yeah i know those are huge effing pistons. there is barly room for the studs the sleeves actually have indents in them so the studs can pass through..is it possible to desleeve it so it isnt so big or would i have to get new cylenders? ive always been kinda worried about this huge bore
