chris1992 Posted May 1, 2007 Report Share Posted May 1, 2007 (edited) "Hey everyone, I just have recently purchased a 97 banshee that was not running. I cleaned both carbs and got it running, but only on one cylinder. I took the carbs back off and cleaned them again, with still the same result. I changed the plugs and still the same thing. The right side runs great, but the left side doesn't. From an idle I could hear the left side start to kick in a little, but with the throttle it would die back off. I got a clymer manual on it and from what the book seems to tell it is maybe an electrical problem such as the coil. Just wanted to see if anyone has had a similar problem, or if anyone could give me a little help with it. I've been in the 2-strokes awhile now, but this is my first banshee, and any help would be appreciated." OK this was someone elses post. i copyed it because im having the exact same problem except my right side isnt running but the left side is.. tim sorta new here.. but i know u guys are the experts. Ok.. the coil, isnt bad, changed the wires, changed the sparkplugs, nothin. itll put.. like.. really a little smoke out.. when its warmed up.. but u gotta look really close to see it... the right side is totally cool, just going up and down, no combustion... left side is.. ok.. not running too good.. but meh.. the banshee is BONE stock except for the tors was removed.. its on the original top end.. it has 65 compression in one side, 70 in the other. its an 89. Im running 250 jets and im close to sea level.. i need some help here guys.. been trying to fix it.. any help is apritiated. thx edit- btw i forgot to mention.. that when i took my boost bottle off, there was some fuel in there. thx Edited May 1, 2007 by chris1992 Quote Link to comment Share on other sites More sharing options...
Michael Jackson Posted May 1, 2007 Report Share Posted May 1, 2007 when u removed the tors did you unplug the big wire running to the little black box up front mounted to the frame near your radiator? your compression is very low too.. stock should be around 130psi each side i believe, year doesnt matter,u can have some 16 year old idiot on a 2006 with the jetting and eveything else totally off and someone with a clue on a 1989 that smokes it..you say u run a 250 main jet, banshees come with 220 main jets stock at sea leval..so did u rejet it?whats your airbox situation? lid or no lid? air filter setup? give some more details Quote Link to comment Share on other sites More sharing options...
chris1992 Posted May 1, 2007 Author Report Share Posted May 1, 2007 (edited) ok umm... i did not rejet it but i do belive the person before me did... the entire tors sytem was removed.. the box, the throttl, the carbs tops, etc. air box with lid, uni filter, all bone sotck, and when i said it was an 89 i was wndering if i should maybe rebore it'? im not sure if 60 is low for a cylinder.. i dont think it should quite be time to bore it yet.. but what do i know? ^^ also on another note, when i replaced the crank seals, the head had some dents and gashes in it from when aparrently, before me, someone blew a piston, it broke apart, and smashed the head, but he never bored it out.. should i fix the head? thx.

chris1992 Posted May 1, 2007 Author Report Share Posted May 1, 2007 so i do need a new top end? anyone know who bores cylinders out here in phx Quote Link to comment Share on other sites More sharing options...
bigboybanshee Posted May 1, 2007 Report Share Posted May 1, 2007 If your compression is that low(65/70psi), you're due for a fresh bore and new pistons. If the reeds are original then I would definitely think about swapping those out too :thumbsup: To be totally honest, if it's on the original top end, then I'm pretty sure the bottom end hasn't been touched either. If it were me, I'd completely tear the whole engine down, inspect all parts and make sure they are within spec, replace all crank seals, etc. (clymers manual is very handy for this). It would be a real disappointment to get a fresh top end on it and the bottom end lets go, just my thoughts :beer: Quote Link to comment Share on other sites More sharing options...
dajogejr Posted May 1, 2007 Report Share Posted May 1, 2007 In addition to what bigboy said...I'd recommend having the crank welded and trued as well... The problem is riding season is starting all over the country right now...most shops are busy with customers work trying to get them finished up for the season...call around, see who can get to your motor in a reasonable time frame!!

chris1992 Posted May 1, 2007 Author Report Share Posted May 1, 2007 i dont have the money to do that... my moms real stingy.. if she has to spend 60 bucks on my quad all i hear is this is rediculas, get a job, blah blah blah blah blah. if i do eventually convince her to get a new top end, shell NEVER buy me a new crank, or even give me the money to get it trued and welded. I cant get a job, im only 14 :/ Quote Link to comment Share on other sites More sharing options...

bigboybanshee Posted May 1, 2007 Report Share Posted May 1, 2007 Try and find some service that your neighborhood may need....wash cars, that should bring in some cash! All you need is a mitt, soap, water, and a bucket. Go to your closest corner store and see if they need someone to stock the coolers and shelves. I used to work at a gas station when I was 15. It wasn't the best but I made 6 bucks an hour to hang out and keep the store stocked If you lived close to Memphis I'd pay you 10 bucks an hour to shovel dirt out of my back yard :thumbsup: Quote Link to comment Share on other sites More sharing options...
dajogejr Posted May 1, 2007 Report Share Posted May 1, 2007 Time to pony up and get some work around your hood, or get rid of that bike...period. Two stroke oil, gas and spark plugs will set you back 20 bucks or so per ride...and trust me, you can fix it the right way now....or pay a LOT more later. I know it's easy for us to tell you how to spend your money...when it's not our own. However, we're speaking from experience. A wise man once said...

chris1992 Posted May 1, 2007 Author Report Share Posted May 1, 2007 ive been trying to explain to my mom that if we dont fix everything up, something could go seriously wrong and i could end up paying 5 or 6 times the amount it woulda cost then, but she doesnt belive me. My dad does, as hes been a mechanic for 40 years, but he cant convince my mom. She doesnt think i should have to spend any money into it. We explained to her when we bought an old used banshee that we would have to put some work into it.. but she didnt listen. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted May 1, 2007 Report Share Posted May 1, 2007 Looks like we know who wears the pants in that family...LOL. Just kidding... If you're gonna get it done, get a job somehow to pay for it. Sitting here asking for us to help you convince your mom to open up purse strings simply isn't going to happen. Quote Link to comment Share on other sites More sharing options...
