Starting problems NC30

[speedy231278]

I doubt that old plugs would refuse to fire the bike up, but it's not out of the question that they've become unhappy with the bike persistently turning over without firing. Apparently if you're lucky, you can sort them out by carefully drying them out with something like a blow torch, although this doesn't always work and there's also a chance you could knacker some perfectly good plugs. I think Honda specify 8000 miles or 12 months between plug changes, although personally I fail to see how something like a plug can go bad based on time if it's hardly being used, and I don't like buying expensive parts just for the hell of it. Looking at my eBay profile, I did mine a year ago, and it was 30 months since the last time it had been done. The plugs than came out were fine, and the bike ran no differently with the new ones. I'd almost certainly not reached the 8000 mile limit by then either, and I figure stuff like that really wants replacing on miles rather than age. Stuff like oil and coolant is a bit different, and I do that at least as frequently as the schedule, if not more so.

Like speedy said, get them on a flame.

I had problems with mine in january as it'd been sat a while and I tried to start it on old petrol.

Out came my dad's blow torch and a bit of emery paper, and they're still fine now.

I took them out yesterday and cleaned them up and checked the gaps the front 2 there was still no spark and the back 2 very very small yellow spark it would spark then that would not. I have ordered some new plugs thought i would try them out if it still does not spark it might be the coils.

Could have... they are frail if they get flooded. Clean them up and be sure that everything else is sorted too.
