slimeball Posted February 18, 2013 Report Share Posted February 18, 2013 Hey guys, Its been about 10 years since I had a banshee. I'll just call my self a Banshee noob because I know nothing about them. I have a couple quick questions. So I got my hands on a Banshee that wasn't running. Hasnt been started for 4 years. I rebuilt the carbs changed the coolant because I had some laying around. Gave a little squirt of starter fluid and blam she started first kick. So now all of the bad. I started the bike and it appears that one of the silencers coughs out a little smoke then either stops allowing exhaust to flow out or stops emitting exhaust. I took that pipe off to see if exhaust was coming out of the 1st half of the pipe and some was but it sounded like fireworks were shooting off so I turned the bike off. Also, I looked under the bike and it looked like gas was dripping from the bolts under the engine. Is that possible? I didn't install overflow tubes out of the carbs at this time so gas was coming out from there. Its possible that it might have overflowed off the engine where the gas was coming out of the carbs. So I guess the questions are, if I have one pipe emitting exhaust from one side and not the other what is most likely the problem. Is it possible to have gas leaking from under the engine? If so whats the general cause? I know these might be obvious answers. I would appreciate the help. Any advice would be much appreciated. Trying to get this thing running good. Heres a video of what this is looking like: Quote Link to comment Share on other sites More sharing options...
sheerider11 Posted February 18, 2013 Report Share Posted February 18, 2013 There is a hole through the cases to drain. What do you mean by rebuilt the carbs? Like new gaskets and jets? Quote Link to comment Share on other sites More sharing options...
slimeball Posted February 18, 2013 Author Report Share Posted February 18, 2013 Should I drain the cases out if the bike has been sitting for 4 years? I guess so. Is that to drain crank case oil? They were gummed up with old gas and rock hard fuel lines so I took all the plastic parts off took them apart, soaked them overnight in carb cleaner and returned them back to what looks like new carbs. The gaskets were still good so i didn't replace those. Quote Link to comment Share on other sites More sharing options...
Sandking Posted February 18, 2013 Report Share Posted February 18, 2013 Clean the jets and adjust the floats. Make sure you have good fuel Quote Link to comment Share on other sites More sharing options...
slimeball Posted February 18, 2013 Author Report Share Posted February 18, 2013 I cleaned all of that stuff. Jets look new. I cleans and blew everything out with a high pressure compressor. I know the air screws hve to be adjusted and I need new pipes which sucks because I dont want to buy stock pipes for 100 and I dont want to but after market pipes to learn the quad is not good lol. I'm worried that I will have to replace the head or jugs/pistons. Quote Link to comment Share on other sites More sharing options...
Sandking Posted February 18, 2013 Report Share Posted February 18, 2013 If fuel is pouring out the floats are sticking or out of adjustment Quote Link to comment Share on other sites More sharing options...

oldskool Posted February 19, 2013 Report Share Posted February 19, 2013 Do you have stock carbs? Tors? A banshee can run on one cylinder, so you got to determine if both cylinders are firing. I would check the reeds if the bike has been sitting for that long. If your sure the carbs are clean, floats working, needle valve/seat are all good, air filter clean, then I would do a leakdown test. Then a compression test. Check and clean ground wire. Check both plugs for fire. Good luck Quote Link to comment Share on other sites More sharing options...
slimeball Posted February 19, 2013 Author Report Share Posted February 19, 2013 @1shee I haven't pulled the reeds, I did check the compression. Was at 100 on each cylinder. I bought new plugs, cleaned the filter. I'm going to double check one of the carbs again.One fell off the wheel when I was installing. might have jacked the float up. I do have the tors for now,. I have a tors removal kit ready to go but wanted tto make sure the bike was running before I installed. What is the green wire your referring to and also what does a leakdown test entail. I guess I can google that part before someone posts the google seach animation on me lol. Quote Link to comment Share on other sites More sharing options...
slimeball Posted February 19, 2013 Author Report Share Posted February 19, 2013 I just realized that I said green wire. I was answering this post while I was cooking dinner. So is it as simple as looking for the wire and making sure its connected/ grounded correctly? Quote Link to comment Share on other sites More sharing options...
erickson483 Posted February 19, 2013 Report Share Posted February 19, 2013 Swap the plug wires and see if the problem changes to the other cylinder. But at 100psi, that thing needs a rebuild Quote Link to comment Share on other sites More sharing options...
HolySheet Posted February 19, 2013 Report Share Posted February 19, 2013 Swap the plug wires and see if the problem changes to the other cylinder. But at 100psi, that thing needs a rebuild X2. I just freshened mine up cause it ran like shit with only 100psi in each cylinder. Quote Link to comment Share on other sites More sharing options...
slimeball Posted February 19, 2013 Author Report Share Posted February 19, 2013 I was hoping I wouldn't have to do that. This bike isn't worth the overhaul. Quote Link to comment Share on other sites More sharing options...
slimeball Posted February 19, 2013 Author Report Share Posted February 19, 2013 So I was looking around for a shop that would do the heads. What do you guys think about this service on ebay?: The company is Lakes motorsports. Anyone heard of them? http://www.ebay.com/itm/321070173293?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649 Quote Link to comment Share on other sites More sharing options...
