Still will not start, Last night I took the white wire off of the coil that runs from the ignition switch and ran a hot wire direct from the plus side of the battery to the coil, Still nothing. I have replaced, Iginition module, sensor plate, coil, plugs, wires, battery, 30 amp circuit breaker, stator, voltage regulator and still nothing. I have 12 volts at the coil with the key on, the bike turns over great with "No Spark" 12 volts at the battery, and the sensor plate test at 4.5-5.0 volts as stated in the manual, I have searched for a broken or melted wire and I can not locate, were should I be looking? This all started after the bike was running like crap and died, would not start so I replaced the battery, when I hooked up the battery the positive lead arched and now I realize that I...

Hey Igot An 80 Xl And Am Looking For Advice On What Jets To Run Pilot And Main. Stock Motor Except For Drag Pipes And Super B Carb. Backfires Through Throat Of Carb Between 2500 And 3000 Rpm

i have an 03 flstci with stage 2 se 1550 kit,the bike only has 500 miles,
in fourth gear only, at 55 mph it starts to howl,i had h.d. swap out the rear
wheel compleate with tire,sprocket,rotor and bearings. nochange,
i asked could it be the trans, they dont know , any ideas anyone.

Wondering if anyone has any advice on this. Just bought a '91 sporty. Have put on about 1000 miles. The bike now has just over 5000 miles on it. No major problems, doesn't run extremely hot (oil is usually around 175-200 when sitting in traffic). When it is warming up it runs extremely jumpy for the first couple of miles. after that it's fine. I get some backfires when decelerating occasionally. The guy I bought this from had it for the past 9 years and never rode it. He didn't know what kind of aftermarket pipes were put on. The heads are now extremely blue. Any ideas for what settings to start at?
Would it be easier to get a new exhaust system and a jet kit to match?
Right now I'm looking at Samson big guns or Hard Kromes staggered. Any thoughts on either of these?...
