Ignition Replaced Now Bad Miss

[dobro]

I would have gone for the low tension lead also as a start but this looks to have been ruled out.

I have had a friend who had terrible trouble with a Ducati about an hour after he bought it and we headed doff on a rally (have mentioned this before but it may be worth a look). His bike missed and farted like you wouldn't believe, one exhaust started glowing red hot and I flagged him down. We limped to the rally site and the bike shop sent out a mechanic (good on them). He found the fault was water down the spark-plug holes, he thought it got there by the bike shop when they cleaned it with a pressure cleaner (hate those things on bikes) and water got under the caps. Dried them, it ran beautifully.

Also thinking about, it if it was fine before the ignition repair (and the bike shop lackey didn't do you the favor of water-blasting your bike) and it missed afterwards I wonder if its an earthing issue? May not be enough to kill the lights and dash noticeably but may be dropping the ECU in and out? Easy to check that with some jumper leads.

Thanks, All grounds on this bike were checked a couple of weeks ago before deciding to replace ignition switch.

Dobro, take off the tps and clean inside tps and connection and I think your problem will be solved. I spent $500 at Ft Worth triump dealer who had it over two months and when I finally got it back it started stalling again after a couple days. I had heard about the tps problem so I took in apart and cleaned it good took about 20 minutes and haven't had a problem since.

Thanks, rocket51. Before the mechanic replaced the ignition switch the bike was running perfectly (except for the occasional failure to start). After the ignition was replaced as I was driving home from that shop the bad miss first began. It could be an amazing coincidence that something unrelated to the switch replacement caused the miss to begin then but I'm not ready to look elsewhere yet.

Ok take the engine out and ship it to me for parts. Put a new one in. Problem solved!!!!!!!!!!!

Hope you take this as the light humor it was meant to be ?

I had a switch replaced on a cruise control on a vehicle. The dealership monkeyed around with it for sometime. It did not fix the problem.

I finally took the vehicle to the dealer where I bought it. They went through everything and decided it had to be the replacement switch. They replaced the switch again, and problem solved.

Possibly removing the switch, and testing it with an ohmmeter for continuity. Try tapping on the switch with a plastic screwdriver handle to induce a short.

Oxidation on connections?

Check battery voltage. Pull seat off and check after starting. Sometimes, a failed cell which is shorting out can fluctuate voltage and hose up electronics.

The problem turned out to be a dirty fuel filter and/or the airbox was not tightly seated on 2 of the throttle bodies. Both were fixed before it was ridden again so I can't be sure the part played by each of those problems. Now, it's running great again!

Glad to hear you got it sorted ! My bet was the crappy fuel filter.

Good to see you have it all sorted

i would think that u could take the air system off and it would run fine until something went in the barrels.

Would the effect be different if the airbox was taken completely off versus leaking air around its fitting on the throttle body? I don't know--just asking.
