Suzuki A100 won't start

[Suzuki]

Hey there, my Suzuki a100 was running fine after rebore for couple of days, but then start sputtering and couldn't give it revs, tried to start it today and won't start. It is getting fuel and air, has a good spark, it has fuel going to cylinder and has a compression of about 130 psi. Does anyone know what the problem could be or things I should check?

Yeah change the spark plug. Spark on the outside doesn't equal spark under pressure. Regularly. Failing that give a quick squirt of brake clean up the carb mouth.

Embarrassing thing on my second A100; riding home on motorway at 110kmh. Engine just dies. Check everything but won't start. Get it home and proceed to go over everything but nothing obvious. An A100 nut pops round wiggles the ignition key and away it went. Seems that the key looks as though it's on, but it has gone just past where it should be towards parking lights. So for me it had just vibrated there. Still good to know and cheap fix.

No ignition? Theres your problem - its not a diesel :facepalm:

There's no ignition cause the plug is rooted but he doesn't want to hear that.

no I did see that and I'm looking for a new spark plug, plus it runs fine without no ignition or battery, cause i have a had it like that for ages.

Its a magneto ignition system so it doesn't need a battery, just its nice if you want your indicators to flash whilst idling, but that's about all. 'Ignition' vs 'ignition switch' was the play on words above and two different things of course.

yea, it doesn't have indicators too, or a headlight or brake light, it more of a bucket racer haha. Been looking at spark plugs, are NGK spark plugs any good? I'm a beginner at all this.

It appears so - yes NGK plugs are fine

Change the spark, started first kick and didn't miss a beat. Thanks F5 Dave for the help. :cool:
