Alternators, brakes...

I realized this last weekend that I have owned my beast for nearly 22 years..and in that time I have never had a complete season of riding with a working electrical system...( thank heaven for magnetos..)
So - the question is - which alternator to fit?...Anyone have any recommendations?...I plan to keep my trusty magneto..

My beast has locked up the tires under braking only once...apart from alloy backing plates - is there another fix for poor braking performance?

Charging systems and brakes

Hi,
If you are a full member, you can scan back through previous posts to look for other peoples solutions, but here are a few,

Charging,
1/ Keep the dynamo and fit a modern solid state regulator (limits the amount of power available)
2/ Alton (keeps original style look, current version gives about 120W)
3/ Car style alternator conversion (few varieties about giving upto 360W, but has advantage of easy spares availability)

Brakes,
Read Know Thy Beast and others, slight oversize hole for spindle, then pull on brakes before tightening spindle will ensure that the brakes are centralised properly.

Best of luck
Neil

I have had a bakers dozen of JG regulators - or its equivalent, none seem to last very long..The generator has been rebuilt by the best so its ok...My wife found out about me riding without lights/horn etc etc..and hastily approved the expenditure on an alternator...lol...and frankly I seek bulletproof, having lived long enough with my beast in "original" guise...

Thanks for the tip on the brakes - I'll give that a go next time I get to ride it..

Go West young man, go West. John McDougall in Vancouver does a very robust Kubota kit that ain't cheap but pumps out mega power. Also for Brakes I can't praise the Vincent Speet Brakes enough from Holland. Twin leading shoes that stop very well.

Call if you wish, I'm in the phone book, or PM for a phone #

I ran a JG unit since 1974 until the Lucas E3L died last year (no problems with the JG) now using Alton, not a huge amount of miles yet, but it seems to maintain a sensible charge level under any conditions; headlight on/off, Lucas Rita since 1980, starts so easily it's embarrassing, but I will post any problems. (Even with the kvf tt it started well)

If you will contact me directly at enw07@btinternet.com I will send you details of my, and Dick Sherwin's, car alternator conversion which is able to give 30 amps. There are over 40 of these out there now with all users happy as far as I know. It will not look standard but it will run all the lights you could want plus heated grips, gloves, waistcoat etc. There are kits for all postwar models of Vins. :)

I can recommend timetraveller`s alternator. I have fitted three so far and have one on order for my Shadow. It comes as a complete kit with drive, alternator and regulator. I have one on the outfit and with a sidecar headlight connected to the bike headlight, it balances on tickover. Fit and forget.:D

Brakes

I Know its mainland and not UK made, but hé they drive it all, Those 2 x 2 Leading shoe brake conversion kits. Whatever you fettle on your original brakes they remain slopy, compared to what one needs nowadays.

I'll be happy to help you set a kit on you bike

vin alternators

Personally I run the Alton system. Ok,cheap it aint! It fits in the original space and provides plenty of power for a headlamp that doubles for a searchlight! The car/ kubota devices may work ok, but for my money are less than aesthetically pleasing. [they look like dogs wosname] . you must make yor own financial decision on this one. Brakes ,You do not say if you run a sidecar! there are too many options to go through without more details of your problems. As my old pal always said" you must always show it who is the master". Good luck in you quest Roy.

I don't run a side car... I do ride too fast, I do like to "bait" harley riders into a race and my brakes ( or lack thereof..) have scared the beejesus out of me many times..
Money, Thank god is not the issue...as the cost difference between all of the alternator "solutions" is not that great..

brakes-or lack of

before spending large lumps of your hard-earnt, a word of caution. consider that the ammount of retardation afforded is governed by the ammount of grip available from the poor old tyre! Lock-up is a very easy way to "chuck it up the road".I tend to think period tyres, period brakes.Your vin, like mine ,is fast approaching sixty years old .Does it really need the extra stresses and strains that yor dream brakes will impose upon it. p.s. harleys also have piss poor brakes. It's those blasted ducati's Ihave trouble with. You could do worse than go to you local voc section meeting and ask the guys there .They will own a selection of machines and have experience of your quest. Be lucky Roy.:)

Although there are several Vincents where I live ( 9..), only one, apart from mine is ridden...the closest section is about 500 miles away...

your points about the stresses of braking on a machine as old I am are well made....My greatest fear is that the amount of my hair that has changed to grey increases with every ride - and I have precious little left that isn't grey..so i am fighting to save it. I think that the real problem is that my standard brakes are not performing up to even their feeble spec.
So you see, the problem is testosterone poisoning which affects my right hand in such a way as to increase the throttle opening beyond what is reasonable, combined with poor brakes...

brakes-or lack of

I neglected to check your location, 500 miles is too far to go to chew the fat. Personally I run aluminium[fake] lightning brakes with am4 linings and standard drums. I figure thats about as good as drums get. At least the tyre will squeal in panic mode. I regularly go to the local [10miles] meetings. Will do some research if you wish, and report according. Regards Roy.

Aluminum backing plates is one option that I am seriously considering...The Dutch backing plates are another, I know that the brakes on my beast are capable of far better performance than they are currently providing and either system would be a serious upgrade - and might well compensate for my reduced age induced reaction time.
All of this will have to wait until spring..my garage is unheated and the temps here can reach -50 in the dead of winter.
My transmission is leaking oil - either through one of the seals..or the joint between the 2 halves of the cranckcase..The generator works, but due to some mystery inside the wiring - none of the charge reaches anything on the bike - battery, lights...and the beast needs its tank and fenders repainted..So you see I am looking at a general rejuvenation....

If original appearance is less a concern than price, you can cobble up a set of disks that won't look TOO bad, for only $100 or so (using used eBay parts), and have braking that will probably far exceeds either the new club 8" brakes or the dutch 4LS, both which are lovely but pricey. And the installation will be totally reversible, for when it come time to send your machine to Bonhams and cash out.

As to electrics, I find all of them either too little (marginal watts and reliablity) or too much (more watts than I need, big ugly installation, and high price). I keep wishing someone would come up with something in between, like the Chinamo was - say, an updated dynamo or premium armature and coil to go in the Luca or Miller dynamo body, and a premium quality electronic regulator. Most of us don't need 120-200 watts, but would be happy with 50-60 - if they were dead reliable.

I am, unfortunately rather too attached to a "stock" look....and I have the perfect antidote to bonhams - my son is named Vincent..and so the beast, hopefully, will go from me to my son, just as it went from my father to me...thereby solving the dilemma of over-priced vincents going to ****ers who polish but rarely ride, have never seen the ton, and are owned by owners rather than riders...
I rode the last 100 miles in the dark to the michigan rally - pitch black night..70 mph..no lights.."building memories.."....and I am still torn as to what to do about a suitable replacement for the miller generator that lurks inside the beast..

Altons seem to be the most stock-appearing set-up, but the Kubotas are hard to spot unless you look for it.

You can have good brakes by having the linings turned to fit the drums, The modern compettion linings are as good as AM4 was and still is, if . you have a lifetimes supply. Enough suppliers advertise these services. But it will cost

It is pretty cheap here in the US to get the linings turned to the drum ID. Truck clutch and brake shops are set up to do it and can accommodate our type of shoe pivots and floating pivots.
