EU politicians have just been informed that breathing air leads to certain death in 100% of all cases and are working hard to find a way to ban breathing in order to protect all EU citizens.

If it thinks the side stand is down it won't run unless the bike is in neutral. I'm not sure, but I think it won't start, either.

([edit] Arfer's probably right, but I seem to recall not being able to crank the starter with the side stand down...

I haven't been on here much that last week or so. Weather has gotten nice here so I've been playing with my own toys. The last I saw you mentioned your battery voltage at 12.5 ? That is only fair. I would feel better about it if it were up to about 13.5 or so. I would also consider putting in some fresh plugs. You have been cranking on this thing a week. I've seen plugs that looked perfect not want to fire after they have been fuel soaked a few times. Just my 2¢ worth. ...J.D.

Battery was charged overnight and now show a healthy 13.3, 12.9 switched, and 11.8 cranking.
Rechecked spark (only in #1) and nothing today. WTH! Cleaned up the sidestand switch and attempted to re-align it to make contact with the sidestand plateau, and it will not trigger the switch when the sidestand is down. (always in up position).

Got sidetracked and decided to put it up for the day.

Was just reading a very helpful thread on the starting system before I checked my post.

This one seems to go through all stages of testing needed.

07 Bonne Black with ARK, AI removed, K&N Pods, Nology Coil and wires, D&D full exhaust, 135 mains/42 pilots, 1 shim @ sea level. Biltwell trackers, Hagon 2810's & progressive fork springs. all blacked out.

Is the side stand switch broken or is it just not getting triggered by the side stand? If it's always saying "up" then things should work fine. If it's broken, and not making electrical contact, it'll always say "down" and the only time you'll get spark is in neutral.

The TBS doesn't have a side stand relay.

That voltage sounds better. Still no spark ? To be honest, I haven't really got into these systems that much because both of mine have been so dead reliable. I've just replaced coils on both of them, like everyone else. But that is all. ...J.D.

I'm going to give it one more day, and follow the steps in the link above, that pretty much covers all steps of the system.

With this in mind, if it's still a non-starter, then it will be parted and sold. I'd hate to have to do such a foolish thing, but have other plans and this was for sale, anyway. The bike was detailed and washed so to get good video to post on eBay and the forum...

If you need anything, make a list and we'll talk.

Hmm. A lot of electrical fiddling on a bike that ran. You said that it fired a bit when you put starter fluid down the carbs? You also said you don't smell fuel. With a carburated bike, when cranking, you are drawing fuel whether the engine is running or not, so you should smell something. I'm leaning towards a plugged jet or jets. (not sure what the carb setup on this bike is).

Water will clog a jet in a heartbeat and fuel will NOT get past it. Depending on access, it could be as easy as pulling the idle, pilot and main jets, blowing them out with compressed air and re-installing. Draining the bowls will not remove water from the jets. If you go down this path, take your time on the idle jet and note the number of turns from its current position to fully closed. You'll need to put it back at this point when re-installing. The pilot jet and main just go all the way up.
You may have to pull the carbs to get at all this stuff. Its fairly easy to work on carbs if you are meticulous and careful, so don't be too afraid.

Carb work I'm familiar with. The lack of spark is my concern, now. I do appreciate your input, though.

Sounds like an awful drastic approach to a bike that ran fine before you washed it. My guess is you got water into the clutch switch. IIRC, the clutch switch is in play under all conditions.

Or, the side stand switch could be wonky. Try jumping it. (only 2 of the 3 contacts are used.)
