A couple weeks ago, I dropped my bike. A little fall, basically just a tip over while the engine was running. Laying on it side the engine was still running until I tried to lift it up and the rear wheel touched the ground.

Once up, I tried to start it took awhile to restart it, but it did. I had a misfire, rode it home about a hour ride and it runs perfect at high speeds, nothing out of the ordinary.

Got home pulled each spark wire tested it for spark and it getting it to the plugs. Replace plugs with new ones and still have it.

Replace the coil and still have the no fire at #2.

Does this sounds like I am in need of a new engine?

 

So you arent getting spark at #2? I had troubles with mine after i dropped it. I had to constantly take the plugs out and clean them for a while, but it runs fine now. I just gave it time and some nice WOT a few times and it eventually worked itself out.

Well I haven't rode it since, just started revved it high a couple of time and shut it off. Been doing that for a couple of weeks now, it still the same.

I check for a weak spark also, matter fact I think if I am not mistaking the test light was not as bright as the other, now that you meantion weak spark.

Thanks,

 

When my bike got dumped, oil got up on the spark plugs. Trust me, you may have to take them and clean them a few times. The oil seemed to never want to clear up. Eventually i got it running good. It would stutter low-end and then once it started revving higher it ran smooth. So just try and ride it out.

just started it and revving it in the driveway isnt good for anything. you need to ride it good and hard to burn off whatever you need to burn off. what you are doing will just make it more prone to fouling plugs

 

Thanks guys,

The weather going to be nice Thursday and Friday that when I be riding to work which is all highway for 70 miles each way. I will be pushing her hard then.

Just did the Cam Chain Tensioner (OEM) and the rattle is going, now to get the hesitation.

 

Hmmmm, no spark on #2 cylinder is not from a fouled plug or from oil or to much fuel and I don't think running the bike is going to fix your problem...

You have an electrical problem, a wire that has come loose or broken to the #2 coil when you dropped the bike.

You replaced the coil on #2 so you connected the 2 wires that run to that perticular coil.

Go to those 2 wires on the #2 coil and start tracking them down to their source and make sure there not bare and grounding, broke or not plugged into the wire harness.

You can take a volt meter and test your good coil wires with the bike running and then compare your results to the #2 coil wire to see what wire is not connected.

Check your plug wire and cap for good connection and if this help does not fix the problem I would look at the black box as possibly failed from being dropped.

It's kind of hard for me to give you any other advice since I don't have the bike in front of me, if it was my ride I would double check the coil wires to the harness, plug wires and cap then the black box.

Good Luck on this fix!

Thank, i will be taking her apart tomorrow to check those items.

 

Ran the hell out of her this morning, pushed her to 125 MPH and she is now running on all 4 cylinders. With the CCT fixed and now got #2 cylinder back she is sweet.

Thanks, guys I was worried that I losted my engine.

Thanks
