xLastShotx Posted May 21, 2007 Report Posted May 21, 2007 My Banshee has a spark issue. I brought it to Rosarito Mexico on Friday. I have had a really hard time starting it lately, I got it started after 20+ kicks and went to the dunes to ride. Everything seemed fine until I stopped and let it idle, when I went to go again I tried to rev up the engine but it would just bog, then it finally died. After that I could not get it started again and ended up having to push it back home. Once I got it home I trouble shot the problem, Cleaned out the carburetors, made sure the fuel was good, checked the spark plugs, and checked for spark. I found that it would only spark sometimes, every 8 kicks or so. What would cause this? The Ignition coil is about 6 days old. The stator and CDI are about 2 months old. Would the engines compression affect the spark? Last I checked the cylinders had about 110 psi of compression and that was about 15 hours of riding ago. Quote
moneybags Posted May 21, 2007 Report Posted May 21, 2007 You might have sheared your flywheel key. Or the flywheel bult might have backed out. That or maby the flywheel craped out on you. When my flywheel took a crap on me. It would get a spark every now and agin. I would rather push a Banshee then ride a 4-stroke. Quote
xLastShotx Posted May 21, 2007 Author Report Posted May 21, 2007 About two weeks ago the bolts that held on the timing plate backed out and took a nice chunk out of the pickup and took a piece off of the the metal rectangle on the flywheel (don't know what thats called lol). I had Rancho Motorsports put the stator and timing plate on about a month or two ago and clearly they did not use locktight... One more reason why I HATE Rancho Motorsports and refuse to even walk in there store and I encourage everyone I know to NOT go there for anything. A few weeks later I had 79 South Motorsports fix all the damage (drill and tap the timing plate holes up to the next size and replace the pickup coil). After that it still would not start, they told me it was the ignition coil, so I brought my Banshee back home and ordered the pickup coil from Ricky Stator and replaced it. After I replaced it, it would start after about 15+ kicks and it seemed to run fine, but whenever I would turn it off I would have a heck of a time starting it back up. After that, that is when I brought it to Mexico and it stopped working for good. After that I took apart the flywheel it appears that some of the loose bolts scraped the inside of the flywheel and the top of the stator. I lightly sanded the top of the stator and the inside of the flywheel till it was smooth again, but it did not help. Do you think that these scrapings may have damaged the Stator or Flywheel? Quote
moneybags Posted May 21, 2007 Report Posted May 21, 2007 If you take off your flywheel and shack it. You might hear sompthing broke inside of it. With my broken flywheel. The broken sound inside of it was so faint. I could not even hear it. Somebody elce could, I could not. It sounded like sand or sompthing inside of it. Careful not to hit your self in the head when shacking the flywheel. :: Quote
Handyman Posted May 21, 2007 Report Posted May 21, 2007 Is it just one side that sparks every 8 kicks or is it both sides?? Quote
dajogejr Posted May 21, 2007 Report Posted May 21, 2007 Is it just one side that sparks every 8 kicks or is it both sides?? Good point..Handyman... Not many people know this, but both cylinders spark at the same time, every time. You get a dead spark on each cylinder every rotation. If the box on the flywheel got marred up from a loose bolt, I'd be getting a new flywheel real quick... Did you check clearance between the pickup coil and flywheel magnet? I try to set mine around .015...close the better. Spec is .018 to .020 I know you have the TORS removed...but are all the wires removed properly/cut/taped off? Quote
xLastShotx Posted May 21, 2007 Author Report Posted May 21, 2007 (edited) Is it just one side that sparks every 8 kicks or is it both sides?? Both sides spark, I am not sure if they spark at the same time because it is very hard to hold two spark plugs on the head and kick it over at the same time, but both sides do spark.. I haven't checked the gap yet, ill have to do that.. It looks pretty close, I don't have a gap thing so I will have to pick one up at AutoZone or something today. I am pretty certain that all the T.O.R.S. wires are properly taped off, I am going to unwrap my wiring harness and double check all the connections. Edited May 21, 2007 by xLastShotx Quote
Handyman Posted May 21, 2007 Report Posted May 21, 2007 Another thought???? Have you tried to swap the plug boots from plug to the other to see if the problem jumps sides? That is if it sparks on one side only. Quote

xLastShotx Posted May 22, 2007 Author Report Posted May 22, 2007 (edited) I'd hate to see a 6 day old coil bad already...but, shit happens... biggrin.gif Yeah, if it isn't the slightly damaged stator or flywheel than it has to be the ignition coil. If it is bad ill have to see if Ricky Stator will send me a new one for free or something. I am really hoping that it isn't the CDI, this problem seems to be reminiscent of my last problem, which ended up being the CDI... No one has answered my first question though.. Does compression affect spark? Edited May 22, 2007 by xLastShotx Quote
Handyman Posted May 22, 2007 Report Posted May 22, 2007 No compression doesn't affect spark. you're going to have compression whether you have spark or no spark. they do not affect each other in any way. Quote

O ok, well damn. I was hoping that my new top end kit that is going to arrive tomorrow was going to fix everything lol. Well it looks like I am going to have to throw more money into this bottomless pit called a Banshee to get it working again. I love my Banshee but when I have to put this much cash into it over and over again just to make it work, it makes me feel like selling it and getting a new 450 :sad: . Quote

Test your ignition coil and pickup coils resistance before buying. get a clymers manual and follow the steps and trouble shoot. dont opt out of banshees for a 4-poke. Quote
xLastShotx Posted May 23, 2007 Author Report Posted May 23, 2007 I just got my new top end kit today (Wiseco pistons, NGK B8EG Spark plugs, Wristpin Bearings, Gasket Kit, and some 80W Gear Saver Trans Oil). I pulled off the jugs took off the old pistons put the new pistons on. I tried to get the jugs back on for about an hour and gave up, they just wont fit. I have never had that problem before with my dirt bike or any of my friends topends that I have done, this is the first time I have tried to do a Banshee top end though... and I am pretty sure this is the first new top end that my Banshee has ever had. Tomorrow I am just going to bring my Banshee over to 79 South Motorsports and just have them fix the whole thing, I am giving up on fixing it myself for now. I have to pay a lot more to have them fix it but I figure they get it done rite and then hopefully it wont break down anymore. Quote
dajogejr Posted May 23, 2007 Report Posted May 23, 2007 You got a one year warranty on Ricky Stator Stators... I just got mine warrantied, no questions asked. Sent it to them with the line item detail from my online banking account..(My receipt is in a box at home, buried.) I sent it to him on a Wednesday, he got it Friday...he shipped a new one on a Wednesday (last week) and it was at my door yesterday...installed and working fine. I was disappointed I didn't get an email or phone call... I called him last Thursday...he looked it up, said it was warrantied, shipped the day prior, and I'd have it Tuesday. I can't bitch about that.... Not sure how much this helps, but I thought my personal (and very, very recent) experience might give you a little insight. Quote
