shawn941 Posted June 14, 2009 Report Share Posted June 14, 2009 i'll try to make this as short as possible,,,i bought this banshe from a used cycle shop. guy didnt know shit about the moter and said he didnt have the previous owners #. although he said it had a 410 stroker motor in it,,,thats all he knew. guy who had it didnt take care of it for shit,,,i got it on layaway and payed a bit much for it,but it was a layaway deal so i took it being short on cash. $2250 plus tax. oil was black, foam air filter was a hard piece of dirt basically,,bike started first kick tho and ran great. fmf fatty pipes,stock head,kein carbs,dont know what size,how can i tell? so anyway,,to the point of the story, i finally got some outsu stock 400ex tire, which hook great on a banshee at about 4 psi. its alot faster than my last piped banshee for a fact,,,changed oil,new k&n 2 into 1 air filter,no lid. i cant even launch this thing in 2nd without it going straight up in the air! no matter how far i lean forward( i weigh 190) it dont matter straight in the air. will whellie 3rd with no effort at all,,4th will wheelie with a little effort. so you guys think this thing has a 410 stroker or what? the motor will come apart this winter and i will know for sure just wanna ride it for the summer. oh, and, compression is at 125 psi both sides with stock heaD, trottle wasnt wot tho,,,i forgot,,,its been awhile,,,lol. what u guys think? sorry for the long post Quote Link to comment Share on other sites More sharing options...
AKheathen Posted June 14, 2009 Report Share Posted June 14, 2009 (edited) all i can think is to adjust your rear shock, longer swinger, launch different? oh, and you can measure the carb bore near the slide by trimming a toothpick till it just fits sideways, then measure Edited June 14, 2009 by AKheathen Quote Link to comment Share on other sites More sharing options...
Burt Reynolds Posted June 14, 2009 Report Share Posted June 14, 2009 Well it has the same power characteristics as my stroker,it will wheelie in 3rd with no effort and in 4th if you pull up. I dont have a problem launching in second my tires just spin Quote Link to comment Share on other sites More sharing options...

shogs Posted June 15, 2009 Report Share Posted June 15, 2009 You could guess all day the only way to really find out is to tear it apart. Why don't you buy a top end gasket kit for 20-30 bucks, see what you've got, and replace the gaskets while your at it. No more wondering :biggrin: Quote Link to comment Share on other sites More sharing options...
wacko2000 Posted June 15, 2009 Report Share Posted June 15, 2009 I agree with the above, Order some gaskets and tear into ti. Thats the only way you will know for sure and have piece of mind. Have you checked what gearing is on the bike? This will affect your launches. I have a 4mil stroker and can launch in 2 with no problem. 3-4 gear wheelie all day with no effort. If its alot different than your last bike and wheelies in 4th it could be a stroker but wont kno for sure until you check it out. Good luck Quote Link to comment Share on other sites More sharing options...

docjcwatson Posted June 15, 2009 Report Share Posted June 15, 2009 Could just be a freak of a motor. That happens sometimes. Could be ported too. Take the carbs off and snap a picture of the intakes, then post it up. We would be able to tell you if it is or not. With 125 in each cylinder though, I would do the top end now. Do not wait for winter. There is a reason that the compression is that low. Quote Link to comment Share on other sites More sharing options...

AKheathen Posted June 15, 2009 Report Share Posted June 15, 2009 if it is a stroker, you would need some serious port height to get 125 in a healthy way, and it would be all topend. unless you are at 8000ft asl. Quote Link to comment Share on other sites More sharing options...

okbeast Posted June 15, 2009 Report Share Posted June 15, 2009 i didnt check the compression with wot,,,how much of a diff would this make? Not that much. Sorry but take the head off, get the number off the pistons and come back and we can tell you if it's got a stroker crank in it. Just because it launches hard and wheelies doesn't mean it has a stroker crank lol. Quote Link to comment Share on other sites More sharing options...
shogs Posted June 16, 2009 Report Share Posted June 16, 2009 Yea dude i I haven't taken my bottom end apart but i'm itching to just so I can replace the clutch, get my crank welded, and do the shift shaft mod and what other tiny mods you can do.I just want to KNOW it can handle the abuse, you know? I was relieved to do my top end when I did because any more abuse and I could of broken something in the engine. If you don't have a clymers manual get one because thats where most of the gurus on this site get all their effin knowledge from anyhow. Top end only involves removing the carb, pipes, and gas tank to get to the head. Gasket sets are like 20 bucks and if you have tools thats all you need.

jbooker82 Posted June 16, 2009 Report Share Posted June 16, 2009 Take the gas tank off and get a pice of rod long engough to stick down the spark plug hole. Make sure it is long enough that you wont drop it down in the cylinder. Put the rod in to the spark plug hole and role the engine over until the piston is at bottom dead center. Mark the rod. Then roll the engine over by hand until it is at top dead center. Mark the rod. If it measures 54mm from mark to mark then you have a stock stroke crank If it measures 58mm you have a 4 mill stroker crank. You need to make sure you keep the rod in the same spot on the top of the piston. Quote Link to comment Share on other sites More sharing options...
