Well, I got a wrong headlight so I'm dumb. So if anyone needs a 7inch 6 volt. lol

I ended up finding a relatively cheap NOS so this is all kind of a moot point. So they are still out there just gotta go and look and have good information. Thanks a whole bunch anyway!

After a good bit of websluthing the headlight is 5-3/4in or 143mm. Any help would be amazing.

Are there any Generic sealed bulbs that will fit in my 1975 RS100B. I'm finding similar bulbs but nothing that seems to let it be known if it will fit. The bulb is a 6 volt 25/25 watt, and I'm not positive but I'm pretty sure they are 5.5 inches in diameter. Any help would be amazing thanks a bunch! Matt R

I just got myself a little RS100B and I know there are a few problems with the wiring. I have not gotten a chance to pull the headlight out yet cause the last owner stripped out both bolts in front (adjustment and open), but I'm presuming I'm having magneto problems because my brake light bulb works fine but I only get brake light and not tail light when I turn the key to accessories(headlight/tail light). Where should I start to check on the tail light problem? Thanks in advance. Matt

Super far south side, Beverly/Morgan Park area. Thanks a bunch, I'm enjoying it so far. Just got my permit and need to get the bike put in my name. Party time!

Just joined tonight (I guess it was yesterday already) I'm the proud new owner of a 1975 RS100B. It runs like a champ but has a few electrical demons right now. I just wanted to do the usual "Hello!" to the new forum I'm not legal yet so I've been cruising around the cemeteries near my house. I'm picking up parts and pieces now getting her road legal so I can insure it. So I'll have questions eventually (especially considering I can't get my tail light working), but for now this is just me saying HI!
