Free yellow banshee Posted September 2, 2013 Report Share Posted September 2, 2013 So I think my piece of shit RM stator is the culprit. Let me start by saying I am familiar with 2 strokes and jetting. I have about 2 hours on fresh top end. It passed the leaktest. The bike started to backfire in the powerband. I took it riding today and it got worse. I tried to bump the mains up 1 but made no change. It didn't really change. I tried a bunch of different mains and nothing helped. The low/mid has always been fine. Now it is starting to backfire all throughout the powerband. I pulled the plugs and they are wet which tells me it's not firing. My mods are.... T5 pipes Stock carbs Cfm airbox w/ k&n and outerwears Boss intake Vf4's Trail ported cylinders Dynatek full ignition Cool head with 22cc domes Jetting.... (at sea level) 320 mains 30 pilots Stock needles 4th clip Air screws are 1.75 turns out (choke tube is in) Can you guys give me some suggestions. I think it's the stator. I bought it before I was a member and didn't do any research. I plan on buying an oem. Do you guys think this is my problem? Where can I get a decent deal on a stator? Thanks.

trickedcarbine Posted September 3, 2013 Report Share Posted September 3, 2013 Could be reeds...... But if the plugs are wet and you know it's definitely a firing issue I'd say start with homing everything to spec per a clymer manual. Then if you still can't tell I'd start with switching one known working part at a time if possible. If not start with new plugs gapped properly and tops tightened, set the pick up gap, clean the carbs thoroughly, sync the carbs, engine/chassis ground, spark plug boots, maybe plug wires, coil, stator then cdi last.

Free yellow banshee Posted September 3, 2013 Author Report Share Posted September 3, 2013 Thanks Tricked. I will check into those things. I believe its the stator or pickup. Everything has less than 4 hours run time. The dynatek coil wires are brand new. I plan getting an OEM stator anyway. I don't want to be stranded with the shitty RM stator. I will check the flywheel for rattling, check pickup gap, and ensure plug ends are screwed on tight. I know the ground is good because I chased my tail trying to get spark, CDI was bad. This thing has given me a lot of ignition problems so far, hopefully this will take care of it. Quote Link to comment Share on other sites More sharing options...
WINDYCITYJOHN400 Posted September 3, 2013 Report Share Posted September 3, 2013 Get a brand new Racetech stator. Racetech FTW! Quote Link to comment Share on other sites More sharing options...

Free yellow banshee Posted September 3, 2013 Author Report Share Posted September 3, 2013 I hope I can get this thing straightened out. I just dont understand why it runs smooth on bottom and mid then pops on the top. Quote Link to comment Share on other sites More sharing options...
Free yellow banshee Posted September 3, 2013 Author Report Share Posted September 3, 2013 Getting ready to go out in the garage and mees with it. I will post results. Quote Link to comment Share on other sites More sharing options...
Free yellow banshee Posted September 4, 2013 Author Report Share Posted September 4, 2013 UPDATE (like everybody should do) So I popped the stator cover off and immediately noticed the 3 stator plate bolts had backed themselves out. I have an adjustable timing plate and a dynatek ignition. It was sitting at +6. Also noticed my flywheel rattles when I shook it. So I will be buying a race tech stator and a used flywheel. I'm sure this was my problem, I'm just hoping that the pre ignition didn't damage the motor. Quote Link to comment Share on other sites More sharing options...
trickedcarbine Posted September 4, 2013 Report Share Posted September 4, 2013 So you have a dyna CDI as well? That could be one of the problems in itself Quote Link to comment Share on other sites More sharing options...
Free yellow banshee Posted September 4, 2013 Author Report Share Posted September 4, 2013 So you have a dyna CDI as well? That could be one of the problems in itself Well I bought the stator and adjustable timing plate first when I had no spark. Put it on and still no spark. Decided to order the dynatek Cdi and coil. Ended up being a bad cdi. When I installed the dynatek I put the stator plate back to zero. Quote Link to comment Share on other sites More sharing options...
Free yellow banshee Posted September 4, 2013 Author Report Share Posted September 4, 2013 Needless to say, I will be putting blue loctite on the bolts. Quote Link to comment Share on other sites More sharing options...
