Turn Signal Mounting Studs

[Polamnus]

What are the threaded studs that the turn signals mount on called? Are they anything special? Where would I go to get new ones, every single one of mine are either bent or broken off.

Thanks,
Pol

Oddly enough... I think that they are called hollow threaded studs. For our purposes, they are of course, metric threaded. Sometimes you can straighten them out enough that they will hold the turn signal on straight..Mine are sort of bent on the front and the signals have that drooping end thing going on..MikesXS sells complete new turn signal units for 10 bucks each..I'm sure they are repops, but look original enough..I'd be temped to buy a couple, but I'd really like something smaller...However, I getting off track here, I don't know where to tell you look for new studs, but would be interested myself. Maybe Mike has a source he'd share, or you could have a machine shop drill out some metric all thread..

I found some good looking smaller brushed aluminum units for 21 bucks a pair, however they use a smaller bulb than a 1156 and I am not sure if the current draw of the smaller bulbs would be enough to work with the stock flasher unit.

Right now I'm looking for the LittleFuse flasher Wahoo650 is using as it requires much draw to flash..I'm thinking it's transistorized and is automatically variable. I guess until I get the flasher thing figured out, I'll be putting up with the droopy front signal stalks..

Let me know if you find some studs though..

John,
I'll continue to keep this slightly off track, I see in my new "Mike's XS" catalogue that he is offering a 2 wire flasher unit. Not sure if it's solid state or not. As for my Little fuse unit, still going strong, and yes it's solid state, so works as long as voltage is above about 11 VDC. No current draw limitations. Also, I have a pair of the stock turn signals from Mike's on mine and they are virtually indistinguishable from stock. But I am like you and now want something smaller. Where did you get your replacements?

I was going to follow up about my Littlefuse flasher attempt. Stock signals and I tried every wire combination possible on the 3 pins, all with no luck. One of them I could get to click when I would signal and cancel, but no lights. So I put the old round flasher back on (it still works) and put the other 3 flashers I've tried (none of which worked) in a box and put them away. I saw a post about a new variable setup that is supposed to come out-that would be the ticket!

That link wasn't mine, but it's a good one nonetheless.

I'm thinking a customized flasher unit should not be necessary, there ought to be something in the Napa inventory that will do the trick. I'll be getting into that in a few weeks hopefully and will gladly report back what I find.

Someone on the Micapeak list gave me the suggestion of cutting a slit along the length of an 8mm bolt with the same thread pitch and the appropriate length. I can't confirm the 8mm measurement since I'm not at home right now, but this does sound like a viable(and cheap) alternative to the originals.

Best,

Hey Matt,

Man, I seem to be having a hard time even finding that particular LittleFuse flasher, the two places I have checked [Napa and Oreilly's] either did not sell that flasher or could not find another brand to cross reference the part number with.. There a few more parts places in town so the hunt is still on!

I have not bought the smaller brushed aluminum units yet, and likely will hold off until I get something figured out abut the electronic flasher..Anyway, not to wind too off course from your question.. I located the lights at a local independant shop. He has these and other small items custom packaged with his store name and logo on the cardboard backing card..So, I do not know the name of the manufacturer, but I will attemp to find out..To expand on the lights themselves, they are a three wire unit, one wire for ground and the other two are for running and turn signal lighting.. I assume that one could connect the running light wire into the headlight wire and then just connect the turn signal wire just as you would the stock units.. Or perhaps, connect the running light wire and the turn signal wires together and simple use both of the bulb elements as turn signals...The mounting studs looked long enough to reach through the rubber headlight mounting ear and head light shell grommets!

I'll try and find out more about these units and will get back to you..

I contacted Custom LED about their signal flashers, here was their responce:

>>>>>>>>>
If you are looking for an adjustable Flasher Relay, your best bet would be to purchase the Libertek F1 from McCoy MotorSports at www.tobefast.com. Our flasher relay project is delayed significantly and may be canceled all together.

Please let us know if we can be of any further assistance.

I found a different website that is currently offering an adjustable flasher unit...I edited my post in the "LED lights for Tail and Signals" thread to show it. Have a look at it.

I tried a different flasher since I couldnt find the Littlefuse brand Mine was no. EL-13 by Tridon-Stant for $8 from Autozone. It works great! From what I understand any ELECTRONIC variable load flasher relay Not Thermal for 12v should work. I just had to switch two of the spade connector postiions. (corrected part no. and added manufacturer and store name)

[Phil]

Oh yeah, I also made a turn signal mount - nice and short. Just center drilled round stock and threaded both ends, but I have access to a lathe which is the key

Guys, I seem to recall that the replacement turn signals I got from Mikes had mounting studs that were both too short (for the rears) and too small in inside diamter for the wire to pass through. I had a machinist bore them out. I found a Yamaha p/n that may help, and because this is probably a part common to most Yamahas of the era it may even be something your friendly dealer keeps in stock. If the rears take the longer stud, and I think I recall they do, the p/n (for a 1980 G) is: 360-83367-09-00. Fronts are 341-83367-09-00. Hope it helps.

Dennis Kirk carries a lot of turn signal stalks and lenses and bulbs so maybe you'd want to check it out. I like the clear lenses but not enough to spring for them and new amber bulbs (about $30 total). I don't know how creative you can get mixing and matching this stuff but I would bet there's a lot of leaway. Lockhart Phillips now carries turn signal lenses and may be worth a look as well. Maybe Targa too..

If the rears take the longer stud, and I think I recall they do,

Pete,

Thanks for the part # info. but it's just reverse on the stud thing..The fronts require the longer studs, due to passing through the oblong mounting "plate" that fits over the rubber grommet in the mounting ears, and also the rubber grommets of the headlight shell, plus the oblong "washer" that fits over the rubber grommet inside the headlight..

John,
You are correct. I reused the stock hollow studs when I put the replacements on from Mike's. However, I just put a set of small aluminum indicators on out of the Dennis Kirk catalog. Part # 21-0471, $21.99/pair. The studs are just barely long enough for the front, good on the rear, but were actually larger in diameter than stock. I drilled out the oblong chrome piece that keys them in place and all worked fine. You can see them in my post under General topics. Just one more option. Next time I'm in the parts store I'll see if I can grab you one of the flasher units if you're still looking for one.

Matt
