Will not reach powerband 06`EC300

- Start date
Sorry, I meant 178 main, 42 pilot, N1EG 2.clip from top and a #7 slide with no notch in.
Temps are around 20c-25c now, 600-150m over sea level.
Was out now, tried #7 slide with notch in it, 1.clip on needle (N1EG), 42 pilot and 178 main. Nice and crisp bottom to 3000-3500, but wont hit powerband when its in gear. It does rev out properly when its in neutral thought.
Going out for a test-run again, now ive locked the powervalve in open position.
Its supermotard converted, so rather running it on the ritch side rather than lean.

I've had my power valve stick open a couple of times and there is a noticeable drop in low end torque. Also sounds baffed out until about mid RPM. It will be interesting to hear what you find out. Did you unhook the rod so the governor balls operate normally?
Unhooked the rod, and took a fastener for the nut. Indeed sounds baffed out. Twice the noise from idle.
Unhooking the PV did nothing for the top-end. Ive been out now, swapping the stator for the KTM 250 EXC one. Havent test-ride it yet. Also installed the KTM CDI.
I did take the multimeter, satt it on 200 ohms, checked to yellow wire, coming from stator to the frame. With both the KTM stator and the GG stator it gave 16-17 and dropped to 0 in a second.
There is continuity from the stator and the frame. Just seen a video on youtube where the guy said there was not supposed to be continuity there?
Same did I to the coil. It gives 10,5ohm. That is the plug-cap to the coil. Is this correct?
Havent done anything to the stator, its standard.
Checked my old stator and coil, and stator is OK.
Coil - (white/blue - frame) on multimeter settings on 20k ohm, it says 0,04. KTM book says its supposed to be 0,475-0,575 ohms. I checked both the KTM coil and the GG coil, both were identical readings. Dont know if any of them works thought.
Stator (yellow-frame) it is 0 ohm.
I was getting similar readings on an auto ranging meter. I think mine were in the area of 18,000+ Ohms from the plug cap to the lead that carries voltage into the coil. Not sure what this means.. probably that we're using our meters wrong.
In any case, the yellow only provides power to the lights. You have a separate winding on the stator to provide spark and the two shouldn't affect one another.
Have you measured resistance on the pickup coil, AKA pulsar coil? It's the little black box that the flywheel magnet passes by to signal spark to the CDI and ignition coil. This should read 100 Ohms, +1/-1 or so.

OK, thanks. Damn, Neil, you are a wizard when it comes to wiring
But I think I solved this.
I think it has been a combination of alot of things. Electrical has been a fault, but just now, I took of the silencer and used a flashlight. Its a used Pro Circuit 296 with a Spark Arrestor. For an unknown reason, the spark arrestor was FULL of packing. The pipe inside had broken, may be due to vibrations. Since I was going to repack it anyhow, I poured 2liter of water. Came nothing out..
I think this is it. Going to repack the silencer tomorow and take it for a ride. This has to be it. It cant be anything else. Ive gone thru electrical components, everything is OK, carb is OK, reeds, piston, cylinder, PV, rod, gas, hoses, sparkplugs, HT wires etc.

haha! Hold your horses. This is my second silencer, and the other one was 100% clean. Same problem there.
But, you can have 50%, and Neil gets 50% for his electrical knowledge

Neils electrical knowledge is 2nd to none! Wish I knew a slither of what he does!
Anyway, I've crossed my fingers and am holding my tongue to the side just the right way hoping you've finally got her running right.
Just got home, got a paper due in 3 more days, so im kinda very busy at the moment. BUT, I repacked half the silencer because of the spark arrestor in the Pro Circuit silencer. The pipe inside broke in half.
EDIT:
Thank you everyone! Problem is now cured! Revs out nice and even! Its not a singer like my old RS250, but either way, its reeving freely!
Thanks!
