igniter box vacuum hose

[Avidrider62]

Drain plug under the bike for coolant, use silica free antifreeze, I'm pretty sure that's what it takes. I sought out "aluminum and motorcycle safe"

Here's the problem. When these bikes won't idle at about 8-900, we adjust the knob. Well, by doing so, you might adjust it to far to allow the butterfly to expose the vacuum passage to the ignitor. At the same time, the butterfly exposes more holes in the bore under it.
The adjustment was needed, in my band-aid fix, due to pilot curcuit issues. I just tore down the ones I'm having issues with. Sure enough, thumb knob adjustment caused the vacuum port to be exposed to the ignitor. At an idle, no timing advancement is needed. What I found was a cpl of the pilot jets clogged. Passeges are good.

I found the root cause of my idle and performance issues.The surge box behind the carbs was 1/2 full of mouse bedding and mouse food seeds etc,that the little buggers had stored there.It was randomly getting sucked into a carb.You can only imagine throwing mouse food into a 4 cylinder engines carbs running at 4000 rpms.If I get this photo posting working I will post some pics

Tiny pics works well, just before you save it, it'll ask what size to save it. 600 x 800 for posting. Then after saved, you'll see options on what picture size to grab, to post here.

I bought a voyager this week and have been getting it fixed up to give to my dad. I have scoured the hose routing info and cannot find where the hose to to IC ignitor is supposed to run from. Mine has a vacuum line from #1 and 2 carbs going to a T and then forward to the vacuum switch valve. Where do I connect the IC ignitor to? Also not sure where the nipple on the #1 carb just above the float bowl is supposed to route to, there is no hose currently.

That is where the hose for the ignitor slips onto, that little angled brass nipple. It supplies the vacuum to the ignitor.

Hello Scott, You should post those pics under a different title , to warn other newbies of spring time issues, this one has cost you much labor so far. Make sure it don't cost ya cash because of a washed cyl. Make darn sure No shells or sticks are holding a valve a bit open and you take it out for a spin with a miss And gas wash a hole, or burn a valve.

Winter storage , gas additive, remove radio 3AMP fuse/even if your are removing the battery (read the book) , tank topped off. and what I use is a small rag that has some window screen around it made to nicely fit the air box inlet, Rodents can not chew stainless or plain steel screening. THEIR ENTRANCE IS CLOSED . Oh and on gas additive I chose Sea-Foam brand.
I have seen all sort of critter make a quick home in just a few days of leaving an engine unattended .
I also have noticed your carb's drain hose looks like it was kinked and never to have been able to flow/fuel ??? Is that correct ?
