I've got a '94 VMax that I've owned for almost a year, and it recently quit starting. It's been modded, but IDK how much. After some investigation, none of the plugs will spark when it turns over. After the first day that it quit, I got 1-2 sparks for every 10-15 engine turns, and now nothing at all.
It cranks real hard, especially since I've got it on a trickle charger all the time, but it just never fires. Interesting detail: when it was firing, it would backfire occasionally (but only when cranking or idling, I don't think it ever did while I was riding). I can imagine that if the previous owner modded the coils to fire every time, then if it misses on the compression stroke, it might fire on the following exhaust stroke that still has FAM left in it, thus backfiring, but IDK if that's actually what's going on.
The fact that I got 1-2 sparks before, and now nothing, leads me to suspect that it might have been a gradual onset rather than all of a sudden. If that's the case, then it would explain why it had been missing a little (before it just quit).
Since they've all quite, I'm almost positive it isn't the coils, but IDK what's between the coils and the battery. It really seems like there's not much.
Knowing these things, where do y'all suggest I look first?
Thanks in advance.
