Made this cool custom mower last year and had to re-invent some kit for it to be perfect. MP3, Bluetooth and a nice paint job, extended the bonnet to hold the bigger engine and to top it off, it cuts the grass really well. They use a different charging to most and a different engine presented...

Oops! that sort of kills that one. I've always found with older vehicles of same make that another key works with some jiggling. I had 4 Ford Cortinas' that would all unlock and start with the same key.

I'd just put a switch in behind the light. an SPDT should do it.

You can give a filament light anything... AC , DC, or static and it will light. In rudimentary systems (Ride on mowers for example) the lights run from the AC feed un regulated so they can only be on with the the engine running and of course get brighter when the engine revs up.

I need to clarify and make an apology. I had assumed, and to a degree was correct by supplying a constant field coil voltage and using a standard reg/rec that I'd be OK. Yes I would, but not ideal. It would cause the alternator to constantly supply a high voltage that would then have to...

The standard for a static good battery is about 13.26 strictly. Therefore a charging unit must supply more than this. Typically at over 3800rpm an XS unit will supply over 14.5V. This figure is supplied after a rectifier circuit that uses the 3 phase pulses from the alternator and gives a DC...

Most regulators dump to ground or through a waste circuit. = heat Pretty well the the way things go. I remember my first "class A" amplifier had heat sinks all over it and it would run cooler the louder you played, the excess power not driving the speakers was dumped to the heatsink. 2 mono amps...

My shake down on the new electrics will effect my final arrangement but I am assuming that the field coil draws less than 3 amps and if so, a simple and cheap hard wired regulator circuit, independent of the charging, (straight from the battery) will give a simple, reliable charge from the...

Yes sir you are correct. To suggest an alternate for the plebian (literal not derogatory) is perhaps irresponsible. My post was intended for the more advanced. I'm doing a rewire using an entirely different set of rules and when I get the chance I'll probably change the system to a PMA type but...

Of course they don't. The field coil in a system that includes a battery will supply the excitation of the coil with the battery. The secret, as I see it, is just to switch the primary system with the ignition. The coil will drain the the system if it's in line so has to be switched before the...

Exactly, all you need is a regulated field coil supply and my cursory measurements now suggest the supply is very flexible. A higher supply to the field coil gives a correspondingly higher output result thus indicating that the field coil voltage effects output. Therefore a limited current to...

The field coil can be excited by a battery if needed. It should just need a +ve signal on the green from a regulated supply. I think people are over thinking it. We'll see next week, I've ordered a 5 wire and 6 wire but I'm going to see how it works with an outboard variable supply for the field...

Green is earth and the regulated wire is the red. Black is activation (the field coil doesn't drain the battery when off). Try this and see how you go.

Try these schematics.. I think you wrongly purposed the wiring.

Well, I've started with a basic strip down to get an idea of what condition the bike was in. Several issues, though none that are deal breakers in going forward. I began by offering up the critical replacement parts, Bars, Rear set pegs and electrics redesign. So far the bars are on and I'll be...

These are my two favourite inspirations so far, both simple and elegant and good detail. I like the look of pipes on the yellow one particularly and tha dark bike seems to have a nice stance but the twin discs are over kill. More than one disc on the front of ANY bike not used in...

As with most builds, it's important to have a vision, but equally important to keep the vision fluid. Reality has a habit of interfering with the best plans. I'm going classic cafe racer with a short 2-1 pipe gathered at the belly and exiting under the RHS pedal. It won't see any work outside of...

By the way this is probably my 30th bike so I'm not really a noob but it's been 20 years, so I need to get my head back around some bike stuff again. Including this I own over over 60 internal combustion engines (that work) I doubt I'll have too many issues but my own impatience.

Hi there all, I'm Bill and live in a small township about 40kms (30 miles for the yanks and primitives) from Bathurst in the NSW central west. I was given a tidy XS about 2 years ago and intended to get it running for a runabout. The major townships are about 40-50 kms away and I don't need to...
