Bike dies?

My bike only has about 800 miles and today it started acting funny. When I'm riding down the road and I pull the clutch in when the idle drops and im just coasting then start tapping the brake on and off quickly it dies? my only mod is the blinkers integrated into the brake light. This started directly after I washed the bike and did the mod, any help would be sweet.

Didn't you just answer your own question?

I just went out and disconnected all the brake light and blinker connections, also I completely removed the taillight converter. The problem is still there, also it is taking longer than usual to start.

Check for standing water or water intrusion on the electrical parts. If it is under warranty take it to the dealership.

If the problem is consistent try the process of elimination. If you just pull the clutch in and let the idle drop without hitting the brakes does it die? If not, then it would make you think it has something to do with the brakes.
If so, disconnect power to the integrator and see what happens (preferably without a tailgating semi fully loaded on wet roads behind you).

Every thing to do with the tail lights is disconnected, theres just some connectors hanging out the back of the bike. I have got it a little narrowed down, the bike is sitting on its kickstand in neutral and its running, all you have to do is pull the front brake handle in and out a couple of times then the bike stutters our dies. it seems to have some thing to do with the relay that has m5 written on it.

without the m5 relay it won't even start but when it is in everytime I hit the brake it clicks. I just dont have a wiring diagram for it so I don't know if it is supposed to do that because it doesn't click when I hit the back brake.

Ok I think I got it, the m5 relay seems to be for the fuel pump!!
But yet when I hit the front brake it engage/disengages, but get this when I hold down the back brake and hit the front brake it doesnt click the relay. This is one strange problem that would be much easier with a wiring diagram.

If the engine is off and the key is on after the fuel pump has cycled, when you hit the front brake you can hear the fuel pump come on then go off.

Trace the wire from the front brake to wherever it ends, look for a rip or short in the wire. I'd take it in under warranty if it's not that.

I think I'm going to take it in under warranty anyway. For now I just unplugged the brake switch from the front, just have to be careful and make sure to hit the rear brakes first.

You still haven't eliminated the possibility of water causing a short.

Wiring diagram is in the manual I am serving.

check the electrical connections are not disconnected on the clutch switch (2 black wires going to the clutch lever support).

Well I woke up this morning and everything was working fine, so it must have been water causing the short. To answer your questions, no I didn't go balls deep using the hose, i was extra careful not to get to much water on the bike. So for now I'll just drive it and when I get some more time I'll trace the wires and find out where the short is.

The dealer found the problem but not before giving me a whole new set of handlebars, switches, and what not. The problem was actually in the rear brake switch connection. for some reason the cover over the connection was flipped upside down causing it to hold water and short out.

They also put a new set of brake pads on the front brakes because of the squeeling noise, but it started squeeling again about 10 miles after I left the dealer.

Did they charge you for the extra, unnecessary, stuff? If not, you came out OK! (If the bike was assembled incorrectly, the repair should be covered under warranty.)

Wait a few hundred miles before worrying about it.

The only thing that bothers me is the dealerships wasteful attempts at throwing parts at the bike untill the problem went away. They really didn't diagnosis anything, but hey, i'll take all the free parts I can get.

That actually seems very odd. You would think a dealer doing repairs under warranty would replace as few parts as they possibly could in order to get it working. They're usually tightwads about that kind of thing.

Not odd at all... The warranty costs don't come out of the dealer pocket, they come out of Honda's pocket. The dealership I believe actually gets reimbursed by Honda.
