ledofthezep Posted November 6, 2003 Report Share Posted November 6, 2003 Well,...am heading to the dunes tomorrow & haven't gotten a chance to look at the banshee yet. Got to thinking though....if I got a cracked reed will it cause it to spit & sputter at WOT? I know I'm going to try some larger jets & another coil...just trying to think of what other things to try that I've not already. So can anyone tell me what a cracked reed or reeds will do to performance? They're still the stock reeds. I also heard about removing or modifying a restrictor plate that keeps the reeds from opening up all the way????...anyone know about this?

ledofthezep Posted November 7, 2003 Author Report Share Posted November 7, 2003 Is backfiring an symtom. I took the plug boots off the coil wires, cliped the wires down just a bit & re-screwed in the plug boots. Shee started right up like always, but now it's not really sputtering at WOT, it's backfiring every once in a while--on both cylinders(not at the same time--random). Plugs look ok.... I think I'll try some new reeds. The only shitty thing is I'm heading for the dunes today & will have to do it when I get there. Quote Link to comment Share on other sites More sharing options...
fixitrod Posted November 7, 2003 Report Share Posted November 7, 2003 Good luck man, I wish I could help. Backfiring sounds lean though. Is the temp colder out? Quote Link to comment Share on other sites More sharing options...
ledofthezep Posted November 7, 2003 Author Report Share Posted November 7, 2003 Yeah,...it's cooler out.....40-50 degrees. Running 270's right now. Thinking about going to 310's...what do you think? Where's boonman at anyway when I need him!?!hehe Quote Link to comment Share on other sites More sharing options...
fixitrod Posted November 7, 2003 Report Share Posted November 7, 2003 It's a jet size about every 15 degrees. If it ran good at 80, I'd go 290's or 300's Quote Link to comment Share on other sites More sharing options...
ledofthezep Posted November 7, 2003 Author Report Share Posted November 7, 2003 Cool...thanks a lot fixitrod, I appreciate someone trying to help me out on this...I'll pick up some 290 & 300 jets & give'm a shot. I've never had any issues with my jetting, from temps 30 degrees to 110 degrees, shee's always ran damn good. So I dunno...I'll try the jets, then reeds....or if I can't get jets until tomorrow I may just check the reeds--going to have to remove the carbs anyway... Thanks again man, Led Zeppelin Quote Link to comment Share on other sites More sharing options...
fixitrod Posted November 7, 2003 Report Share Posted November 7, 2003 Just doesn't seem reeds would crack on both cylinders. You say you have backfires on both cylinders. Is it possible you have bad gas. Quote Link to comment Share on other sites More sharing options...
ledofthezep Posted November 7, 2003 Author Report Share Posted November 7, 2003 I dunno...that's what I was thinking...because it doesn't backfire consistantly,...just every once in a while, randomly on each side. The gas was the same gas I was running all weekend, bought it when I got down there like usual...ran fine Friday night & Saturday until Saturday evening. I'm bound to get it figured out. I'll be running fresh gas this weekend also. We're taking off for the sand in about 5 minutes...so I'll post back on Monday & let ya know what I find. Thanks again, Brandon Quote Link to comment Share on other sites More sharing options...
ledofthezep Posted November 10, 2003 Author Report Share Posted November 10, 2003 Well guys,...4 cases of beer, 1 weekend at the dunes, 2 spark plugs, new carb boots, new jets later...shee's still doing the exact same thing! I got to looking when we got down there & saw some little cracks in the bottom of the carb boots...so I pulled the carbs off again(went up a jet size & re-cleaned the carbs AGAIN), replaced the boots(they weren't cracked all the way through, thank god), pulled out the reed cages & the reeds were just fine, no cracks at all. Put everything back together, put in some fresh gas & plugs....same problem. So I'm almost 100% sure it's electical. Coil, cdi, or stator...but I don't know that it's the stator--has only about 20hrs on it & it's from yamaha. I pulled the side case off & the flywheel was spotless, no moisture in there. So I dunno...may just have to take it to a shop & have them figure it out---when I have the $$. Anyone want to buy a banshee?hehe j/k...just fed up with it & pissed,...but I do have a '99 shee w/mods for sale. Quote Link to comment Share on other sites More sharing options...
banshee370 Posted November 10, 2003 Report Share Posted November 10, 2003 Led: have you tried closing the gap on your plugs some? An old school way of testing your ignition is to close the plug gap some. (helps w/ weak ignitions) If you find it running a little better than you may want to look at your ignition (cause of a weak spark) Sometimes a bad ground will cause this too. I would also check the gap at the pick up coil. Quote Link to comment Share on other sites More sharing options...
fixitrod Posted November 10, 2003 Report Share Posted November 10, 2003 Yeah, I think the ground was mentioned eariler. I'd go there next. Quote Link to comment Share on other sites More sharing options...
. Posted November 10, 2003 Report Share Posted November 10, 2003 a little off the subject but get those stock reeds out of there. They suck. Get yourself some dual stage boyesons. I like the non carbon fiber ones myself. They are stronger and all but I dont feel they flex enough and if you break one, they tend not to burn up in your engine like the other ones do. 1-2 hp notice, and all the snappiness you'd ever want. Completely changed my quad in how it reacts. It actually does what I want it to when I want it to now. Quote Link to comment Share on other sites More sharing options...
Blacksmith Posted November 11, 2003 Report Share Posted November 11, 2003 I say this problem in a buddy's bike a couple of weeks ago. We spent a lot of hours on this, tore everything on the bike down a couple of times. Turned out the problem was that the gap on the the pickup coil was too large. Didn't know the exact spec so I used the old match cover setting used on combines and the problem went away. Anyway, it is something to look at, more so as you say you changed these parts only 20 hours ago. Quote Link to comment Share on other sites More sharing options...
boonman Posted November 11, 2003 Report Share Posted November 11, 2003 Sorry Led!!! I don't know how I missed this post!!!! I had the EXACT same problem with my bike, and it was the primary wire on the coil not being on all the way and it was also loose. It has happened to me twice so far. I tighten the connector with a pair of pliers and it goes away, but it came back once. I would also check the pickup coil. That could be the problem as well. Backfiring is usually lean, but it can be electrical, and throw you for a loop. Usually the most frustrating problem is a simple one that is overlooked. Check for loose wires, be them ground or other.... Quote Link to comment Share on other sites More sharing options...
ledofthezep Posted November 11, 2003 Author Report Share Posted November 11, 2003 Thanks to all for the replies! I checked the gap on the plugs & on the pickup coil, all were correct according to my bible & my g/f's dad tried setting the pickup coil a bit closer & it made no change. I always check plug gaps before I install them. I'm going to try pulling the coil & everything off the g/f's bike & see if that's the problem. I checked the wires & connectors--took a little wire brush & cleaned the coil's connector & checked the wire's connectors, pinched them in a bit & hooked them all back up and still no resolution. It's getting cooler out now & I plan on stripping everything down this winter & cutting un-needed tabs & mounts on the frame, gussetting & powder coating....so I'll probably re-wire too & see if I can locate or fix the problem. But I'd still like to ride some before it gets real shitty. I'll probably try switching the stator if the coil doesn't work. Oh yeah...(.)...I plan on getting some V-force reeds in the near future.
