Help please, 08 R3T not starting

[Bob R]

Cam timing is good. Seems to be a very weak spark. Ideas?

Battery voltage drops to 11.7v when turning over with spark plugs out. With charger hooked up and feeding 80A to AGM battery it starts at 13.8v and when starter is cranked it drops off to 11.7v. Still looking for ideas.

check for 12 volts on the coils.
if u have a test light u can put it on the terminal and see how it is blinking when the computer grounds the circuit.
check your ground circuits make sure they r clean and good
ground left off.
bad ecu.

if it starts with the charger hooked then maybe u need a good bat?

Not starting at all. Turning fine, spitting some, but not starting

I'm the one with the problem. Here are some photos of the cam and crank timing marks as those are the obvious suspects. Helpful tip for anyone that doesn't have the cam jig: Micrometer jaws will fit in the cam holes and one tooth off would be obvious. I used a straight edge to line up the arrows to eliminate any optical illusions. The crank sprocket dot was missing so I had to use the dots on the crank itself.

Just did mine, and yep, cam timing looks good.

If the cam timing is off at all it is probably no more than one tooth which I don't believe would keep the bike from starting. I may take off early today and run over there and add a second set of hands and eyes to the problem.

My thought as well...it may run like crap, but it should still run. If the cam timing appears that close to being perfect then it certainly could not be off enough to prevent it from starting. I would be looking elsewhere.

I guess I would be concerned about the crank sprocket dot being missing to insure correct timing. Since you have been moving wiring around under the tank I would be concerned that something has been disturbed.

Are all fuses good? Fuses 1,2,3,4,6 and 7 should have power across them with just the battery connected. 5,8, and 9, I believe, receive power with the key on as well 10 for the park and tailight circuit. Other things to come under suspicion would be a faulty alarm if equipped, connector contacts, faulty neutral switch, clutch switch, sidestand switch. If you have fuel and spark along with adequate battery voltage it should be running. But you knew that....

have u tried to see if that dot on the crank is in the right spot when the compression comes up on #1
??
when turning on ign does the stepper motor retract then come out to idle position?
air temp sensor hooked up?

Battery voltage drops to 11.7v when turning over with spark plugs out. Same with plugs in. With charger hooked up and feeding 80A to AGM battery it starts at 13.8v 14.2v and when starter is cranked it drops off to 11.7v and stays there while engine is cranking. Still looking for ideas.

@DEcosse , any thing electrical or is this a normal drop off? I have never heard of a Touring ignition switch going bad like the Roadsters. Any ideas? I think mechanically everything is OK.
