Trouble starting.

At the tech day recently I put in an iridium spark plug and adjusted the valves. Bike ran great. It is still running great once it gets started, but the past few times I've started it cold (in the AM or after sitting all day at work), it really doesn't want to turn over.

One thing I noticed is that the choke lever pulls back a little once it is set now...didn't used to (I have read about this happening). I tried holding it all the way deployed and it didn't seem to make a difference. Yesterday after work it REALLY banged away for about 20 seconds until I closed the choke and started it with a twist of the throttle, then applied the choke. This morning it didn't kick so hard, but it sure didn't want to turn over. In addition to the new plug, I put in a new battery several months ago, so it shouldn't be the battery.

I'm going to get some seafoam and throw it in the tank, but it doesn't seem like bad gas either. Like I said, it is running great once started. Any ideas?

Mine has been a bit fussy lately, as well. In my case it seems to be the operator.

What works is to open give it full choke, no throttle, and hit the starter. Any other settings and it will refuse to start easily. Even though I know that, I find myself trying to start it with a bit of throttle, or only partial choke. Doofus.

When you say it "really doesn't want to turn over" are you referring to cranking speed, or that it doesn't want to fire up?

If it is cranking speed, there's got to be an electrical issue - the new batterry is down on charge or there's a bad connection.

If it doesn't want to fire, then I would suspect the plug and go back to the stock plug to see if things get better.

You changed only two things before this happened - the valve lash and the plug. You'd have to have been so far off on the valve lash for it to be a factor that you can forget that as a cause.

Hey Tom,

It just doesn't want to fire up. It cranks plenty. That's what has me confused. I've been trying to start it the way you suggested (choke full, no throttle...which always worked like a champ in the past...and was a hard habit for me to break [the honda needs some serious throttle twiddling]). It just knocks though. But it worked fine after the spark plug change. The only thing I can think that has changed recently is that the heat wave has ended and it is cold again. But that was never a problem before.

I've never seen this issue before. It is not like the starter is weak, and the spark seems to be there based upon the sound, but it just won't 'catch' right away like it did. I think you're right, though, it's gotta be the plug. I'll run some seafoam through it today and mess with the plug this weekend if neccesary. Weird.

Thanks for the feedback...any and all ideas including screaming at the bike welcome.

D

Plug.

Might also check the cheesy plastic fitting for the choke that screws into the carb. They crack and break very easily. Don't know if that would cause a problem or not.

And it wouldn't hurt to sacrafice a chicken to Sparky, the God of Ignition.

Thanks man.

Dan -

That's right, you're in The City - the sudden rise of humidity (I presume the heat wave going away would cause a rise in humidity) might be a part of the problem. Seafoam would flush that out.

My best guess would still be the plug.

I like the chicken idea, but Sparky might also be looking for a jigger of rum and a nice Diplomaticos.

Damn. And I paid extra for the iridium. That spark plug owes me a sixpack and a burger.

Had the same issue with a Honda 4 wheeler.. Thought I'd do my self a favor and get an expensive spark plug.. 2 weeks later it started acting up, hard to start, not idling, etc..
Changed it out to a $.79 Champion plug and it ran like a top til the day I sold it.

Update

So, I didn't say anything for a few days so as not to jinx it. Friday I went and bought a few cheap plugs and some zip ties (unrelated). I was all set to do the plug Saturday. Did NOT feel like taking off the plastic. Went fishing. Sunday...changed my oil. Still did not feel like dealing with the plug so I rationalized I'd 'give it another week'. Well, the bike doesn't start quite as easy as it did before, but pretty darn well now.

I don't know whether it was the seafoam (wouldn't be surprised...as I have said...I sweat by SF), bad gas, luck or whatever, but the bike starts OK now.

AND, I have to say, I think the iridium spark plug makes a little bit of a difference. A little more snap in the acceleration. Maybe I'm tripping...I don't know. And I refuse to question it.
