Starting Issues

All bikes are different but never use the enricher when warm. Turning the throttle will work on some bikes and not others. You just have to find the "Trick" that works for your bike. If I turn the throttle on my RoadStar it will never start...
Yeah, like most have said, it sounds like I've got a fuel issue going on. I'll have to check things over and possibly adjust the carb.

I figured it was weird having to use full choke in San Diego.

One thing I noticed (which may or may not be normal), there's a clear line of tubing running from a nipple on the top of the carb to the bottom of the bike (not connected to anything). What is this? I definitely need to reroute it regardless...

I'll bet it doesn't take but around half a dozen failed starts to drain a batteries cranking amps down on these bikes. Just multiply the CCA by the number of seconds and convert it to amp hours. Subtract those amp hours from your battery amp hour capacity and it might surprise you. I have a 4 1/2 year old Braille and I might just try it out to see how many driveway starts I can get out of it for real world data results. If I do, I'll post it here.

Recommend pulling of the air filter and see if gas is spraying into the carb from the main jet ,the carb adjustment is easy to do but it may not be the issue.

That line in a carb overflow ventline. It doesn't connect to anything but it will mist. I run mine to the bottom of the bike between the motor and trans

Ok, just for you. I did 3 sets of 3 starts on my 4 1/2 year old Braille for a total of 9 starts in the driveway. Battery voltage at the end was 12.55 VDC. I have not kept the bike on a tender and rode it once in the last two weeks. It is now on the tender to be ready for work tomorrow since I did this evolution.

My bike might make two revolutions before it starts. If you had a problem and it made say 5 or 6 or more your outcome may be a lot different. Anyway sounds like you have a damn good battery.

Wow - I doubt mine would get through 9 starts. Guess I have some troubleshooting to do.

So I fired it up this morning after having battery fully charged. Tried no choke and half choke after twisting throttle 3x. Didn't fire at all. Went full choke and started no problem.

Let engine warm up, but still died when reducing choke. Top end hot to touch.

Ya know my bike idles at about 12.6 and when riding goes to about 13.5 or so and has ever since I bought her.. she has a Dakota set up that shows me the voltage and so on.. haven't actually put a fluke on her to double check.. what would I have to do to get her to idle with 14 volts charging? Everyone I have spoke with says it's unique heard of on any kind of bike with a high performance engine..
No reason to charge at 14v some of the newer AGM 14V for prolonged periods of time will cook the battery. 13.5-13.6 is about all you need. The high quality float chargers are Max 13.4 - 13.5 for that reason

If for some reason you just want it to idle at 13.5v then you need the compufire 3 phase VR and Stator. It's about $300 and IMO I don't really see any need for it.

What Choke? We don't have a choke.

Same difference. Gets more gas than air...
You're right about "More Gas than Air". Enricher unblocks a passage that dumps fuel in carb and is more efficient than the butterfly choke application. Choke creates more vacuum and therefore more fuel.

You're right, it doesn't matter but it is nice to know which bikes have chokes and which ones have enrichers.

Dropped bowl and checked over carb. Looked clean and didn't notice anything obvious impeding jets (.32 and .78) or fuel line from tank.

Hooked up fuel line to watch bowl fill. Didn't seem to be any problems.

Plugs looked black to me. Guess I'll try carb setup procedures next.

Bike came to me with V&H big radius pipes (no baffles) and a cone air cleaner.

I didn't either, just found it interesting that dentdudes was charging so high and made me curious.. I'm from the automotive field where 13.5 give or take is almost perfect charging, on bikes I've always had about 12.5 or so at idle and about 13.5 while moving.. just didn't know if maybe these were different and needed a higher voltage due to the high performance engine

Going to replace plugs and redo carb setup.

Also, as I was working on carb I noticed one of the screws was missing (See pic). does this go directly into the carb? Just curious if this is increasing the air going in and causing some of my issues or if it's just an attachment point (obviously needs to be replaced either way).

Having to enrich the bike for every start and not actually riding it will make the plugs foul (what you are seeing). If you can get it running and turn the enricher off, it should clean off the plugs going for a short ride. Its best to check your plugs after riding to get an accurate determination of what is happening in your engine.

No baffels and cone air cleaner , these engines do not do well with no baffels and the cone air cleaner can be an issue depending on its a installed position too jmo.
