dwet6 Posted December 16, 2009 Report Share Posted December 16, 2009 I am really reachin out here cuz im just baffled with this machine. a little background info is last time i took my banshee out my exhaust pipe connectors let loose and my pipe fell on my wire harness and shorted my stator coil. since then i have fixed the damaged wire, replaced the stator, new flywheel, new crank, new pistons and rings, and new coolhead with domes. I have spark, oil is good, gas is good, mixture is on the money and i just cannot get this thing to start. I dont kno what else to do. I refuse to take my machine to yamaha dealers becuz frankly they just halfass everything and do not kno what they are doing. Does anyone have any ides, please help. thanx Quote Link to comment Share on other sites More sharing options...
01banch Posted December 16, 2009 Report Share Posted December 16, 2009 If you are sure that it is 100% fixed try to pull start it. Quote Link to comment Share on other sites More sharing options...
Bansh-eman Posted December 16, 2009 Report Share Posted December 16, 2009 You said your getting spark so I assume you pulled the plugs and verified this right? When you kick it over 5 or 6 times, open the throttle wide open and stick your finger down inside the carb and see if you can feel a little bit os gas on the inside of the carbs. If not your not getting fuel more then likely. If they are a little wet, try hitting it with a little carb cleaner and then kick it over.

dwet6 Posted December 16, 2009 Author Report Share Posted December 16, 2009 yes i pulled them and checked them personally, i did take the carb off and apart and cleaned it, i have done nearly everything i can think of Quote Link to comment Share on other sites More sharing options...
AKheathen Posted December 16, 2009 Report Share Posted December 16, 2009 did you hook the choke tube back up? did you adjust the pickup/flywheel gap correctly on the stator? Quote Link to comment Share on other sites More sharing options...
dwet6 Posted December 16, 2009 Author Report Share Posted December 16, 2009 i dont kno what you mean as far the gap, i kno i have my timing set at +4 is that what your talking about? And i dont think i have a choke tube, i mean i have a choke but i have my carb setup the same way i had it setup when i my quad was running. i dunno Quote Link to comment Share on other sites More sharing options...
Idontknowwhy Posted December 16, 2009 Report Share Posted December 16, 2009 (edited) There's 3 tabs on the outside of the flywheel line one up with the pickup and I believe the clearence should be .020 Edited December 16, 2009 by Idontknowwhy Quote Link to comment Share on other sites More sharing options...
dajogejr Posted December 16, 2009 Report Share Posted December 16, 2009 There are two tabs on the flywheel, one for each cylinder (by they way, you get a spark on both plugs at the same time, in the cylinder that is not near Top Dead Center (TDC) it's just a wasted spark) Set that .015 to .020. Spin the motor 180 degrees, check the other tab. There is a small fuel line between the carbs if they are stock. You'll notice stockers only have one choke knob, this fuel enrichment circuit feeds between the two carbs and this tube is needed. If you bunt the ignition wire, I'd try a new harness and grounds, to the frame and motor. Also, did you remove all of the TORS crap properly, both unplugged components and crossing the wires for the throttle/parking brake? Did you replace the stator with a Ricky Stator piece of garbage? That could be the problem as well. Quote Link to comment Share on other sites More sharing options...
NickisGod Posted December 16, 2009 Report Share Posted December 16, 2009 im dwets long time buddy, and i personaly helped him build this motor. youve guys seen my shee and with that said ive done 99% of the work to my bike and a few others so im no rookie in the feild. i can give you guys a complete run down on this bike. he purchased the bike almost a year ago, its a 2001 (correct me if im wrong josh) and from the get go it had some issues. the first thing i noticed was the power band or lack of. at the time of purchase it was .75 over unported, dual stock carb setup, toomey t5s, RS 100w or 200w (i forget) stator set at plus 4. at first i thought he has bad gas, no pun intended. after we burned the first tank of gas nothing changed. still a very weak, unpredictable popping powerband. my next assumption was jetting. he took it to bob weavers out here in WNY and they tighten a few bolts, greased his arms and charged him $185 may i add i took no part in that. so then i suggested that 2 into 1 carb, to simplify his bike. to our surprised nothing changed. still on the hunt for the culprated i heard chattering from the lower end, i suggested bad crank and when we were pulling the engine apart i notice a damaged flywheel pick ups from a jaw puller. we replaced the flywheel and nothing. we took the top end apart replaced the badly burnt rings, added a cool head with 20cc domes rode it for ten minutes with the same symptoms untill his stator coil was shorted and burnt up. about at the end of his line he bought a oem stator and put it on the adjustable plate, new pistons rings and bearings, new weisco stock mm crank, and new seals all around. the night we finished it the woodruff key snaped idk how so we were never able to start it. ive talked to him about it and he claims he cant get it going. i havent been able to get over to his house to help him but i think he has a delievery fuel issue. the bike has spark, no doubt about that. the top and bottom end is brand new...... the only thing thats left on my book could be the reeds. he still has stockers but they appear to be in good shape. sorry for the research papper lol but if i dont get his bike running he might murder me for talking him into buying a banshee. joshs bike has been like pulling teeth, everytime we've worked on it something has always gone wrong.

dajogejr Posted December 16, 2009 Report Share Posted December 16, 2009 Is this a running issue or a starting issue? If it's fuel delivery, pour a little premix gas into the back of each carb. If it starts, it's a carb/fuel delivery issue. If not, it's a spark issue. As long as you put the top end back together, and it has a reasonable amount of compression...it should at least start. If it doesn't start with a little fuel in the carbs, remove the end of the plug wires, trim back 1/2 inch, then replace the spark plug caps with aftermarket NGKs (about 5 or 6 bucks each). If it still doesn't start, replace the Ricky Stator Stator with a stock OEM one, used...of course. Stock coils hardly ever go bad...but the factory end caps do. Replacing them with NGK caps is one of the first things you should look at. Does this bike have a single or dual carb setup...me confused?

NickisGod Posted December 16, 2009 Report Share Posted December 16, 2009 (edited) as it stands his setup is this brand new Stock weisco crank brand new .75 over pistons 2 into 1 carb exposed filter +4 oem stator on adjustable plate t-5 pipes pro design cool head w/ 20cc domes stock reeds lol i think i know more about his bike than he does lol, talk about obsession. as far as running vs starting i think hes stuck at starting, maybe he'll chime in sometime today.

dajogejr Posted December 16, 2009 Report Share Posted December 16, 2009 You guys ever leak down, compression test and squish test this motor? Quote Link to comment Share on other sites More sharing options...
NickisGod Posted December 16, 2009 Report Share Posted December 16, 2009 josh is like a kid on christmas morning. no. i think hes coming over today, i will check those. what numbers should i be looking for. correct me if im wrong compression should be in the 150 range squish .015 and leak down zero.

dco3100 Posted December 16, 2009 Report Share Posted December 16, 2009 Just to cover all possibilities, take the filters off the back of the carb and cover the opening of one carb with your palm(sealing it completely.) Then kick the bike over once or twice(not too hard) If gas pours out then that carb is putting out fuel. Do the same for the other carb. I recently had this problem as to my left side float was staying stuck closed(for some odd reason) and it wouldnt start for nothing. Tapped on the bowl a few times, heard the float drop and started first kick. Worth a try... Quote Link to comment Share on other sites More sharing options...
dajogejr Posted December 16, 2009 Report Share Posted December 16, 2009 IF the squish is .015...the motor will make a real nice noise for a few seconds before it grenades itself. AIR GAP between the flywheel and pickup should be .015 to .020. Squish should be at or around .045 (that is where the squish band of the dome and piston nearly meet..and the clearance between them) With 20cc domes, at or near sea level cranking compression on a healthy motor should be 160ish or so... Make sure you're testing it properly. dco...read above, he's got a single carb setup. Quote Link to comment Share on other sites More sharing options...
