Corroded Stator Plate, No top end power

[bcjones6]

My banshee has no top end power, it dropped off on a ride. It is a new complete rebuild. I have checked top end compression and it is fine. I have checked and cleaned the carbs, and I beleive they are fine. It seems to run fine at idle, but as soon as you rev it up a little it bogs. When I take the plugs out they are soaked and black. My TORS has been removed and all emergency brake stuff has been removed. I mentioned the corroded stator plate because it wasn't like this when I reassembled the engine. Also my magneto appears to be rusting a little, it wasn't like that either. Could my crank seal be leaking and causing this, is there an easy way to to determine if that seal is leaking without doing a leakdown test? I put all new seals in the engine when I rebuilt it. It has a new top and bottom end. Also I checked the reeds and they appear to be fine. The plugs are getting fire, but I'm not sure how much.......Any ideas??????????????????????????????

Does sound like it could be a stator...crank seal I don't think so, you blowing oil anywhere? When at WOT does it backfire at all?Sputter?Shit all over itself? How about idle, up to WOT how does shee perform? May get you some carb cleaner & check for some air leaks too.

If I try to go WOT it will kill the engine. It is not blowing oil anywhere. Any idea's as to the corrosion on the stator plate. What normally happens when the pickup coil or ignition side of the stator goes bad......... Thanks

1st stator that crapped out it did just that, crapped out...no warning symptoms at all, I'd just been out ripping around, stopped for a smoke & didn't get it started until a new stator was installed.

 

Last stator...it would idle, rev up to about 3/4 throttle & then fall on it's face,...would spit, sputter, backfire here & there out of either side. I checked/swapped, cleaned, recleaned, everything, and I mean everything, coil, cdi, everything but the stator. I was about to take it to the damn stealer, sad huh. But I said screw it, I was wanting to advance the timing anyway, hadn't had luck with the stock stator so I decided to try a RickyStator stock wattage stator on an adjustable plate. Installed it, advanced the timing +4 and shee's been scream'n since.
