11AGUY Posted March 8, 2012 Report Share Posted March 8, 2012 just finished up a build on my 2003... bored to 64.5mm and installed Wiseco pistons..... upgraded to billet water pump and billet gear, new Tusk clutch kit with springs, rebuilt the carbs with stock jetting and needle clip position, replaced reeds with Tony Dukas Carbon fiber reeds, removed the TORS with motion-pro kit, drilled and tapped carbs with idle screw and replaced stock sliencers with DG silencers on stock pipes.. heres the deal, carb slides are in correct, tube between carbs is installed and i think I got the throttle adjusted correctly.... I got the banshee to idle correctly but when I give it some throttle it just sounds really weak and falls on its face.... when I put it into gear and try to drive it just dies on me.... I have removed the TORS and the entire parking brake and installed an MSR Clutch perch.... I didn't cut any wires, just unplugged all the connections at the hard plastic clips.... I am leaning towards the problem being a jetting and need to upgrade my mains (which are currently 200 and 25 pilot)..... also, the pipes don't fully seat onto the cylinders not matter what I do... the new o-ring that came with the top end kit made them a bitch to get on... i didn't feel or see any exhaust leak and don't believe it to be an issue but have attached a picture anyway... PLZ give me your advice and help me make her completely sea-worthy!!!! thanks Quote Link to comment Share on other sites More sharing options...

troyzstang Posted March 8, 2012 Report Share Posted March 8, 2012 Did you unplug the Parking brake box? i had the same issue. Unplugged the parking brake box and problem solved. Good luck. Quote Link to comment Share on other sites More sharing options...
11AGUY Posted March 8, 2012 Author Report Share Posted March 8, 2012 I unpluged the parking brake and removed the entire assembly.... is there a box that I am missing..... thought I did this step by step, is there an actual box.... removed the entire perch and wire from the throttle assembly and disconnected all wires.... just did the jetting sheet and said I need 210-220 mains (i have 200 now), possibly 27.5 pilot and possibly 2nd clip position.... what does everyone have there air screw at????? 1.5 or 2 turns out???? Did you unplug the Parking brake box? i had the same issue. Unplugged the parking brake box and problem solved. Good luck. Quote Link to comment Share on other sites More sharing options...
11AGUY Posted March 8, 2012 Author Report Share Posted March 8, 2012 just wondering if I should change out my mains to 210 or 220.... is that why it sounds like crap and has no power??? running too lean??? I put it in gear and it just pukes on itself and then dies..... like it's not getting enough fuel/has enough power to take off Quote Link to comment Share on other sites More sharing options...
007banshee Posted March 8, 2012 Report Share Posted March 8, 2012 Try bigger pilots first. Quote Link to comment Share on other sites More sharing options...
11AGUY Posted March 8, 2012 Author Report Share Posted March 8, 2012 I'm gonna wok on it today... grab some 27.5 pilots and 210 and 220 mains from the shop.... gonna unplug the parking brake sensor from the CDI as a member stated that could be the culprit (sensing a ground) even though I removed the parking brake wires going from the handle bars to the wiring harness... if no luck i'll mess with the air screws turning them in half each, if no luck i'll play with the jets and needle... sound like the right thing??? at idle my plugs are a nice mocha/tan color when I pulled them.... Try bigger pilots first. Quote Link to comment Share on other sites More sharing options...
11AGUY Posted March 8, 2012 Author Report Share Posted March 8, 2012 not the parking brake... started it up and same problem, put it into gear and it died after idling for 10 minutes... idle sounded great but just doesn't sound right when you give it gas... turned the airscrews in 1.5 turns and tried to restart a few hours later and it wouldn't start.... turned back to 2 turns out and it still won't start.... i don't think it's getting enough fuel Quote Link to comment Share on other sites More sharing options...
camatv Posted March 9, 2012 Report Share Posted March 9, 2012 check float height make SURE bowls are on the right side's install the OEM needles that you took out. make sure both slides are opening. you didnt by chance leave a rag or towel or someting in the pipes maybe?

Float height is spot on, carbs getting fuel, spark is weak but there (might have to check stator/flywheel)... The bowl with the brass tube goes in the carb with the choke??? Took it apart, but prior too wouldn't start again Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted March 10, 2012 Report Share Posted March 10, 2012 That's exactly how my bike was when my reeds blew apart on me. My bike back fired and took them out. It would idle okay, but anything after that was just a bog. Or dead. The only way I could start it was pop start it too. Won't hurt to check sounds you'll have the carbs off. And also are the pistons in the right way? The windows face you when you pull the reeds? Quote Link to comment Share on other sites More sharing options...

And also are the pistons in the right way? The windows face you when you pull the reeds? brand new wiseco pistons that are in the right way.... pulled the carbs again, floats are opening and closing, jet needle and needle jet are brand new.... Just installed brand new carbon fiber reeds during the rebuild.... I am in the process of break-in... so as far as the reeds go, now that I have the carbs off, I should be able to move the kickstarter and see them open/close correct?? Here's the predicament... the bike is acting the same as it did prior to rebuild and now it has all new parts... the only thing I couldn't get it to do before was idle and I'm pretty sure that was due to gummed up jets.... same issues all together, froggy throttle response, put the bike into gear and it dies... when I checked spark yesterday, it was very weak and difficult to even see the blue arc...the only thing that I didn't check was the stator and coil..... possibly a bad coil, pick-up coil, stator or CDI... also, I know that the lighting is separate, but none of the lights work.... wondering if there is a set of shorted wires??? the guy that did my cylinders and carbs is a top notch mechanic for a local motocross team and said due to the fact that I only bored .20, put new reeds and only put new silencers on, my jetting shouldn't really change that much, plus the plugs are a perfect tan color.... so the bike would start and idle in the morning, now it won't start at all???? also, checked compression yesterday, prefect 120 psi in each cylinder... going to do the prescribed continuity and resistance checks today after i pick up my new multimeter..... any suggestions guys... keep-em coming, we'll figure this out!!!! I'm freaking determined to do this with your help..... Quote Link to comment Share on other sites More sharing options...
Larry's Shee Posted March 10, 2012 Report Share Posted March 10, 2012 When you have flywheel off check it and clean any rust off stator, inside Fwheel and off nubs on outside. Any possibility of trying different flywheel? Quote Link to comment Share on other sites More sharing options...
11AGUY Posted March 10, 2012 Author Report Share Posted March 10, 2012 there's actually a local guy that is parting out his banshee... so maybe I can grab his electrical system..... we'll see.... I think there might actually be a little rust on mine... i'll check pick-up coil gap as well When you have flywheel off check it and clean any rust off stator, inside Fwheel and off nubs on outside.
