NC30 Race wiring loom diagram
For all you NC30 racers and people alike...
This took me a few hours to make, i even made a complete new loom for my racer and it works perfectly.
Enjoy peeps!

Fuel pump?

Yeah, because when you're at full throttle down a straight, as the bike is gravity fed you can sometimes run into fuel starvation problems.
The fuel pump is a racers necessity in my opinion, but is optional.

Re: NC30 Race wiring loom diagram
Right on. The track I run at doesn't have a straight long enough to do that! LOL.

Re: NC30 Race wiring loom diagram
Also, for those considering a fuel pump, it's an absolute necessity to wire in a "tip switch"....otherwise, as you're sliding on your back, your bike (also sliding) will continue to pump gas and likely be in flames as it chases you into the gravel. The tip switch will kill the power to the pump when the bike is on its side.

Re: NC30 Race wiring loom diagram
RAM air necessitates a fuel pump. As this is a wiring diagram for a race-prepped NC30, I'd say it was essential.Harley Godzisz wrote:Yeah, because when you're at full throttle down a straight, as the bike is gravity fed you can sometimes run into fuel starvation problems.

Good to see you're still a gobshite though, and a sarcastic one at that. And if this was all your own work, I'd be tempted to offer kudos, but as you've clearly simply redrawn an already freely available schematic, I can see no value in what you've done here.

Re: NC30 Race wiring loom diagram
Lol!
There isn't a schematic that has a fuel pump and bypasses the keyswitch.
This circuit totally relies on the singular fuse in the main relay, thus allows for less wiring.
There are similar loom diagrams out there, but not the same as this.
The reason behind me doing this was because I was fed up with having to cross reference the Haynes manual with notes I had made. Also the fact that my old loom was just red and black wires!!!

Re: NC30 Race wiring loom diagram
Are you speaking from experience? I have never had any problems with my race bike. It has the HRC fuel tap mod to negate the vacuum but even on a ~1km straight, it has never starved.Harley Godzisz wrote:Yeah, because when you're at full throttle down a straight, as the bike is gravity fed you can sometimes run into fuel starvation problems.

Re: NC30 Race wiring loom diagram
I have done the fuel tap mod so no vacuum pipe needed. This was the first mod to the bike I ever done.
And yes I am speaking from experience. Going down straights I have had issues of fuelling problems where the bike was drinking more fuel than gravity would allow making the bike die!
Putting on a fuel pump rectified this problem. :-)
