RVF 400 coils?
ok guys, brother asked me to post this! unsure what he means but here goes
does it matter which HT leads goes where on the coil cylinders?
quick example upper ht lead goes to cylinder farrest away from coil?
so does it matter if the ht leads are mixed up on the coil?
i think we have the 2 rear coils the wrong way round? unsure if the firing order is different because of this, as keeps flooding my spark plugs and knackering them
soiled full of oil =/ so unsure if it's just that?
honestly im a bit unsure what i'm talking about, my brother asked me to type top paragraph, all i know is something is up with coils/ht leads, i think they mixed up, does this matter?

Re: RVF 400 coils?
It doesn't matter. The NC35 runs what is known as a wasted spark arrangement. As both the front and both the rear cylinders fire at the same point of the crankshaft revolution (although they are fuelled 360 degrees apart), they share the same coil pack, and it fires on every revolution of the crankshaft. So, each cylinder gets two sparks per full cycle, but only one of those has any fuel to burn. The only way you could mix up the cylinders would be to connect front and rear. You're not going to manage that with stock HT leads, and I'm pretty sure the stock ones can't be mixed up either.

I'm not speedy, but yes, nc30 also runs wasted spark
