intermittant noise in front cylinder . . .

I think I see . . . I would want a button or switch that would interrupt or break the circuit? This old skool style button was made to go on the bars . . . but I assume it would close the circuit when mashed and I want it to do the opposite?

Yeah,your horn button is a normally open switch,you push the button to complete the circuit...horn blows...A normally closed switch opens the circuit when you push the button...With that switch(normally closed)the horn would be blowing all the time until you pressed the button...

I found one on Ebay that looks exactly like mine (see pic above) except it has 2 wires (momentary on/off, whatever that means) and it's supposed to work for horn or engine shut off.
I suppose it works either way depending on how it's wired? Bet a dollar it doesn't have wiring instuctions .

Here is a schematic I drew up in 2010 of my electrical system, minus the horn which I'm not running anymore (chops don't need no stinking horns, turn signals, etc. LOL). Since I drew this up, I included a 30 amp fuse between the battery & regulator - simple chopper style - and the whole system has worked flawlessly for two years now . . .

I would like to go with the momentary button simply because it's retro (read: elegant), plus the price is right at $18. Nearly all of the kill switches I've seen are quite pricy & would look out of place on my scooter.

I'm gonna practice LONG and HARD getting used to the jockey shift/suicide clutch/kill button on our mostly isolated back country roads until I feel confident enough to go forth into "real" traffic.

Some toggle switches look retro and are less than $18.00 and when you flip the switch you'll open the circuit...no juice flowing...If you use a NC momentary contact switch and the bike is still rolling,your plugs could fire again when you let off the switch and the circuit closes again...
I think for a kill switch you might be better off with a toggle switch rather than a horn button type momentary switch

I was planning on attaching the button on the handlebars just above the left grip. I'd just have to stretch out my thumb and push.

I don't want to use a toggle switch on the bars . . .

You could find a switch like a snowmobile kill switch, it is made to mount on handlebars, and on older sleds usually is mounted alone. You want it near your dominant hand, as in a quick exit you don't have time to think sometimes. Check with a small engine repair shop in your area, they should have some catalogues that will even show old listings. Looks similar to the pic you have, but with two wires. Likely mid 70's sled on down. Hope this helps. If you have not got one in a week or two, msg me and I'll see if I can find one at the sled graveyard at the cottage next time I'm up.

You guys are right. I'm still searching the web - I doubt the Shack will have a switch that will attach to 1" bars. Here's something I found that might work . . . it's intended as a dimmer.

did you get the manifold josh?

ok I just tracked your package it arrived at Scotland neck north Carolina . don't know were the hell that is. is that the post office that services you?

Scotland Neck is 7 miles north of here. We have a Post Office here but it's only open half days now. I GOT THE PACKAGE TODAY! The adaptor looks great, BP, you did a fine job - everything lines up perfectly. I was gonna take a picture, but in my excitement, I assembled everything and got it on the bike. There was no need to sand anything. Took longer than expected as I had to tweak the carb brace that holds the carb up and had trouble getting the new intake clamps on. Started it up and it idles fine. No vacuum leaks.

I can't ride quite yet as the jockey stuff hasn't arrived - I thought the release arm and heim joint would have been here by now. But I did tell Kevin there was no hurry because the bike wasn't running then. Hopefully the stuff will arrive tomorrow, the last decent weather day . . . after tomorrow, the temps will drop drastically - highs in the 40s & low 50s all next week with rain . . .

Paul, I will be going into the recording studio sometime next spring to make a CD. If you are interested, I'll send you a copy . . .

Awesome glad it was to your liking ! I would like a cd please! Let me know how it runs . Also disregard the message I left I was just worried that you had not gotten it yet.

Here is a pic of the carb on the bike & a pic of the shifter mocked up . . .

Looking good!
