just finished putting the HMF full system on and a k&n. got the JD jetting kit, followed instructions to a "T" on jetting specs 185, 45, and 2.5 turns. I am not getting any spark, cant ark it out, wire tester comes up negative. fuses look good, not really sure where to go, anyone have any suggestions.

Do the KTMs have the throttle cable safety setup like the Outlaws with the KTM 525? On the Polaris there is a TPS on the carb that will kill the spark if there is too much slack in the throttle cable. If you have an electrical connector at the throttle unplug it and see if you can start it. If that fixes it you need to remove some throttle cable slack.

It might be an out of adjustment TPS on the carb as well. Here is more info on how to fix it:

When you turn the key do the lights on the dash come on?
If so, check your safety lanyard - take it off and on a few times and also check that you plugged the connector back together after having the front cowl off.
Check the throttle has about 1/8" slack in the trigger before it starts to pull on the cable. If it has no slack in the trigger it will trip the TPS and just wind over with no spark.
The TPS on the side of the carb will have a dash of green paint on it for allignement, check that you haven't bumped it while the carb was out.
Did you plug the TPS connector back in above the carb after you had it out?

All very basic things, but easilly over looked.

Unscrew the plug cap and check spark from the wire the caps are known to go bad.
It probally is the TPS out of adjustment it doesn't take much movement to get out. I just went through the same issue. If you are getting spark check valves. Also if the cable is to tight it won't let the tps switch reset. Hope one of our suggestions help. Good luck!

More than likely its your TPS on your carb. This is the usual cause. I've had mine move on me a couple time. Real easy to adjust.

got her dialed in, someone who has connections needs to tell ktm that the tps sensor is gay porn. on the positive end, brand new bike, running awesome...idle is a little high but other than that the bike has much more torque and hp than before...atleast noticeable gains to me. i have not ridden a bike with the other exhaust options but i cant imagine having a whole lot more than i got from the hmf. thanks for the suggestions...greatly appreciated...
