Earth Upgrades (Bulding More Ground Wires)

[Neosophist]

am i the only one who thinks this is a complete waste of time and effort

No.

It will only make a difference if the standard system is at fault or not adequate.

I think someone came up with a winning idea "extra earthing"

I think its rediculous it dosent take long to figure out if you have an earthing issue just use a multimeter and test the resistance. All earthing point should be serviced as part of a major service and the loom inspected for damage to the outers that could cause water ingress and corrode the wires.
Battery terminals should always be covered in a light spray of grease or oil to protect them or even beter terminal covers.
I agree with fastdruid if you are uprating the current consumption then new wiring should be utilised but then you should consider the switchgear as well.

The switchgear is alright as druid's mod involves using a relay / extra wires to handle the current rather than run it directly through the switchgear like the original japanese low wattage bulbs use.

I wouldn't say it was 'my' mod as per se, I just went by http://www.vsource.org/VFR-RVF_files/NC ... mRelay.htm" onclick="window.open(this.href);return false; but I wasn't keen on mounting the relay by the connector so went to the extra effort to mount it by the Hi-Beam relay. I went rather overkill on the wiring tbh but decreasing the losses in the wiring by using heavier duty wire seemed to make quite a difference[0].

Saying that though, I'd do nearly the same again[1] as I prefer to go down the "Do a good job now so you never have to touch it again" route.

Although I missed this one before for modding H4 bulbs to fit, I just snipped the tabs off, this is quite neat

[0] Again though the placebo effect comes in, it *seemed* brighter but with no measurements was that just me fooling myself that all that work was worthwhile?
[1] I think I'd leave out the power relay on the NC35.

Sorry i didnt realise. As you say using larger cross-sectional area wire is better i was involved in a development project last year with high voltage lighting circuits and on that system we proved that even if you used the cable rated for the amperage you can still gain up to 10% extra output with a larger cable so it may be that you where seeing an improvment. But that was a rather specialised system. Of course with larger cabeling you have the greater advantage that the connectorisation of the cable will have a larger surface area and not be as much of a weak link. Its amazing when you compare the wiring in a car with xenon and a car without the wiring is rated at a much higher current.

althought i do believe if the bike is running and running well the earth lead kit isn't going to make a differance but i'd be up for one of ricks bolt on kits , my bike has a powder coated frame which has caused me headaches in the past so maybe this earth kit would just bring continuity back up to 100% and give back the edge the powder coating has lost

or i could fit it and find nothing has changed, who knows,but rick i'll be up for the kit once you have it sorted

keep us posted on it anyhow

So - here`s what I`ve done on my NC and I`ll happily supply it as a kit for a tenner if anyone else wants to follow suit.


Original battery earth point with extra lead to rear coil and heavy duty (65/030) lead forward to...

...a bolt in the original fairing mount point on the engine plate which carries the harness earth wire, an extra lead to the front coil and...

...another H/D lead down to the upper starter motor mounting bolt.

May do no good but I can`t see it doing any harm!

i hope my cheque found you safely,oh and they are very very nice looking spark plug caps..

my RO earthing kit arrived today and just in time as i was putting it back together after the headbearings where fitted


nice,simple and straight forward and a few minutes later it was fitted ,and i didn't even need to take the bottom rad off to fit the starter motor cable.



now i am probably one of the biggest sceptics of this but i thought someone is going to have to put there hand in there pocket to see if it works.
i have had trouble with the powder coated frame before so lets see if there is any difference. one thing i did notice was,after i fitted everything to the bike and started it to make sure i hadn't forgotten anything ,i came off the choke sooner and held a nice steady idle.
not that it was all over the place before but a nice constant idle....maybe this is the start of things to come.

[Neosophist]

ooh looks good. ^_^

[royster81]

oh yeah it's nice piece of kit,rode the bike last night for 7 odd miles and it hasn't hampered the performance of it but i think i need a longer road test to see if anything has changed other than the stead idle and lack of choke on cold motor,i thought the bikes sounded a little different,sounded a little deeper or the sound of the exhaust was a little "fuller" but this might have been the fact i hadn't ridden the bike in a week and i had no ear plugs,i will investigate this but on a longer road trip


over all i'm well happy with ricks kit,if all it does is give a stronger spark giving a better idle i'd say it was worth the £10 or so it cost

[royster81]

yep something feels different,the bike feels like it picks up revs from low down smoother...don't know why but...
