Yeah, Im glad its done, I can breathe a sigh of relief, get back on here and check out the other builds, and get stuff ready for windber. Projects like this usually take me a couple of years....

I'm gonna sneak out after dark tonight and take a spin. somehow ill mount the camera to my helmet visor.
 
Meet the Roadwidow, a mix of roadster and blackwidow. It has a high power 30watt LED headlight and a DC charging system with battery. The engine has been rebuilt with a new billet rod, valves, rings, 94 series dynocam, coil, points, condenser and a rebuilt Dellorto carb. The swingarm has a greaseable bushing pivot and it has sebac springs on new hydraulic shocks. All recent rechrome, paint, relaced wheels, cables, every component has been inspected, refinished, replated or whatever it needed it got. Its easy to start, idles smooth and pulls hard throughout with a very strong midrange.

plastic rechrome.....finally got it back

After four months I finally got my headlight bucket assy. back from south bay chrome. They had to do it two times to get it right. I almost gave up, used a borrowed bucket for the build off and windber. I must say it was well worth the wait it is absoloutley beautiful, better than factory rupp chrome. Total was $88+ shipping



 
Did a little polishing today............
What is that wheel hub from?

I sent the headlight housing out for a rechrome. I have no idea what its going to look like but for the price ill try it.

Ignition is all back together with new points and condensor, timing is set at .035 Btdc, and the flywheel taper got lapped.









theres alot of room to add more turns to those lighting coils. I might have to play with them next winter.


The clutches are in great shape, did a good cleaning, sprayed some dry lube on the friction surfaces and replaced the jackshaft bearings. I have a new belt on order.









Did you just pin the fly fly wheel around/over the crank tapper?
I'd like to know how adding more tunrs to coils comes out, if it works i'd like to do the same.

The regulator rectifier came in today, nice little unit, heres the spec pages.



Where did you pick this unit up? how much did it cost?

The Bike looks AWESOME!! would you like to share some DC lighting components? I have a 71 Roadster 2 I'm dying to get better lighting on!! Looking @ LED's ,, but the Rectifer installation is still stumping me.. Info would be a great help..

Thanks.

the hub is a factory rear rupp hub.

My original trail tech regulator died...... infant mortality. I replaced it with a similar one from a JD L120 lawn tractor (because I had it). It is wired in just the same, and will power the LED's without a battery. The alternator is currently only a single pole in use....I am still hashing out details of the double pole with inventorpardue and a few others....but just tying them together wont work, they kill each other. It may be as simple as winding one opposite direction....

you could keep the system as is and use the AC input yellow wires on the regulator...one to ground and one to the post on the engine connector that corresponds to the head light circuit. you should get a good DC out put on the red and ground for battery and then LED. the other engine wire is the taillight and could be left alone.

Anyway, all of it came from ebay, the LEDs china as I cant afford any US made ones. I have a several spares if your interested....

You need to find some radio/HAM enthusiasts i bet those guys know all about coils. it all else fails could one be tied in like it is another and another used to charge the batter maybe with it's regulator? or being on the same circuit or battery still have the same problem?


for the crank tapper lapping do you just through a dab or laping compound on there and spin the fly wheel round and round?

There are methods to accomplish that with frequency sensing relays. But the application usually calls for multiple independent alternators running connected buses.

Maybe run two separate rectifier/regulators to a common charger? Pretty cool you're running LED's with no battery though.
