Dr600 starts but backfires exhaust get red-hot cannot open throttle change power source coil pick up coil ignition box still the same thing @
Hi, Cecilia_alve and the usual suspects are:
1. Retarded ignition timing.
2. Retarded cam timing.
3. Bent or burnt exhaust valve.
4. Massive air leak.
5. Intake manifold cracked or damaged.
6. Intake manifold seals have failed.
7. Wrong heat range spark plug.
8. Fuel delivery system running too lean.
9. Faulty Map, O2, MAF, TPS, sensors.
10. Faulty advance mechanism.
11. Faulty VOES switch.
12. Aftermarket exhaust headers tubing too thin.

Why was the pick-up melted - are the problems related, perhaps, perhaps not. I think it likely to be a broken coil causing the misfire, but as laways check spark plugs, leads, fuel delivery, first before spending cash. Try and borrow a coil from another similar bike to see if it works, if not it is down to tracing the whole ignition system and checking every component for breaks, splits, bad contacts, etc

Testimonial: "excellent just what i suspected"
Have fun, I don't know why it can't be as simple as just install the part and put it back together. You will have to swap wires around until you find the right combination.
Hope this helps.

SOURCE: xt 500 has weak spark(flywheel
It sounds to me that you have done most all of what is needed. Just take some fine sandpaper to the magnets in the flywheel. After sanding, wipe it clean, then spray it with carb cleaner to remove any possible residue. Now give the magnets a spray coating of clear polyurethane coating. The flywheel will never rust again. Replace the source coil and install a new spark plug. A plug that is carboned up can lessen spark voltage. The last item is the battery. A weak one can rob power. Please rate my answer. Thanks.

Please remove sparkplugs and hold them on engine connected to cable and check for blue intense spark on both plugs after that when connected and if the engine still does not start if possible please try with a new set of sparkplugs maybe that should do,all provided the coils are engine specific, wish you good luck
