6 volt tail light -Jawa 477

tweakedlogic

Been Around the Block
I have a Jawa 477 that I'm molesting into a cafe/bobber. It has a 6 volt system and I have been unsuccessful at locating a tail light I am happy with. I would love to run LED, but i know this is not possible due to the 6v system.
For the few of you that know the 477, I plan on mounting it between the upper mounts for what used to hold the rear fender. I had it measured but have lost the paper, or it's with the bike across town. It's somewhere around 4 inches gap.

Any web resources for tail light in 6v? I have exhausted all local shops. I have searched, but I guess I'm too stupid to find what I'm looking for.

FYI: I'm also rebuilding the top end, polishing the combustion chamber, up sizing the carb from 24.5mm to 28mm. strutting the rear end, spring seat, chopping a front fender from a cb350 to make the two fenders for the 477, stripping all but head light and tail light.

Get a 'normal' 12v and fit 6v bulb.

That is what I have to do, but I can't find any I like that will fit. I'm looking for a web site or two that will have lot's of choices and all measurements listed for the lights.
I found one that i liked ok at a truck stop, but the lamps are funny. I can't find a 6v equivalent.

Its a piece of East German communist era junk.
Piston ported engine that needed new main bearings before first service. (MZ was same, but, MZ 250 would do 85~90mph)
When fixed it will hold 65~70mph for miles at a time as long as pre-mix is correct (or is that a later one with oil injection?)
Dont let kick start flip up as it can go all the way forward and drop bike into gear (for those who don't know, you push 'gearchange in, rotate it up and it becomes kickstart)
I'm pretty sure it has DC dynamo, check carbon brushes (find washing machine repair shop if you need new ones, stock electric motor carbon/copper wear better)
The alloy is generally much better quality than Japanese bikes of similar era and polishes up real well.

The inventor, Frantisek Janecek, was born in Czechoslovakia. He came up from nothing, and was the only manufacturer to have a tested and modern motorcycle after WWII. The original company was taken over by the government. He opened other manufacturing plants, one in Canada, where this bike came from in 1975.
It had oil injection, now removed.
these bikes were very popular in some circles for their reliability under abuse.

Has someone peed on your shoe or something to make you want to bash someone's bike you don't own or know anything about?
 
Okay, fine.
Did you have to be so negative?
Instead it could have read:
"I've had a few of those. the weak links are this and that, and here's how to fix it." Instead I got " your bike is shit", when all I want is a tail light that is attractive.
But it's fine. you meant no offense, so it's over.
Back on topic.
Anyone know of a web site with lots of tail lights? Non-LED

Although, I did see on ebay a pair of tail lights from a Model A that say "STOP".

What do you guys thing? too hokey?
 
I don't mind those taillights - reminiscent of the old Vincents :p A bit pricey though.

A lot of dirtbikes run 6V so you shouldn't have too many problems finding stop / taillight combo bulbs. Which means you can get just about any 12V bike taillight and swap in a 6V bulb. That makes your choices pretty much unlimited.
