SOURCE: motorcycle started backfiring when giving

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

SOURCE: i have a 1990 CDI-box and need to know whate wire

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.

SOURCE: Changed coils on Harley now it won't start just pop or small backfire!

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

Exhaust glows red hot

Mazda rx 8 creates a lot of heat, to fix this you must change out the coolant every 20k miles, with the mazda brand coolant i think its called mazda f22 coolant, the engine stays hot due to the high RPM engine, you may want to check: ignition coils, cat, coolant, and do a compression test.

the sump oil deteriorates if too hot and that destroys the engine

Having problems with my 86 model suzuki dr600 ran it as it stopped just would not start again just died. A friend of mine has the same bike we have tried the coil and cdi both parts worked on his bike .....

Have you checked your fuses?
Checked your carbs for debris or fueling issues.
If an electric fuel pump, does it 'buzz' when ignition on. If non electric (most likely) are you getting fuel to the carbs?
Have you checked your filter, fuel tap and or vacuum lines.

Hi when i start my 650 savage & leave it ticking over the manifold glows red hot & then changes to a purple colour is this the norm! rgds steve

The exhaust manafold should NOT glow red, check for intake manafold leak, this can cause a lean running condition and can lead to severe engine damage.

1982 Suzuki GS850 GL will only run with the starter button held

Obviously the CDI is picking up power from the starter button. Check the ignition key switch for proper operation. Chances are that whatever fried the loom also fried part of the switch. Alternate to that, trace the wire powering the CDI system, disconnect it at the source (starter button connection), then find a power source that is live only when the key is turned on and then hook the CDI wire up there.

an I get a “very helpful” rating on this answer?
