Well, after nearly 1700 trouble-free miles the P200's "issue" has once again reared its ugly head. For the third time now it's blown the spark plug out of the cylinder. The first time it happened was on the Thursday after the Rally. Then again less than 100 miles after that, so I put a new plug in it. That plug was removed once or twice since then, and always properly tightened when reinstalled. Tuesday night the problem returned. I put a new plug in, but haven't checked to see if it's loosened itself.

The threads don't seem like they're stripped out, but the plug doesn't seem to go in quite like it should either. I think I'm going to have to pull the head and have a Helicoil installed, unless someone has a better suggestion.

I'm betting it's crossthreaded or stripped. Hows a bout a new head?

Wouldn't a helicoil be cheaper than a new head? Just wonderin'.

Sure, just I've never had a chance to use one.

I'd put a new head on it. They're pretty cheap, and should be foolproof. Helicoils can be done wrong, can be a pain in the ass, and can take time. Besides, you probably need to decoke the head anyway!

If you know how to helicoil do it, or take it to a shop that does it. Most shops are out of p200 heads, so used you be your best bet.

I've done several helicoil repairs in the automotive world and never had a problem. If there aren't any other "issues" I think you'd be better off keeping the head that you have.

Besides..... how can you be sure the ears on the new head will fit under your helmet???????

Rough ride home on Tuesday, then, Kevin?

It makes my bike sound super healthy--good luck.

Are you using the right length of plug?

1. Plug length is correct.
2. Happened on the way to the TNR. Had tools and new plug with to fix along the roadside. I'm certain the bystanders witnessing the guy in the Power Rangers suit were amused by me shaking my hand in the air after contact with hot spark plug. Me...not so much.

So Kevin, did you figure out how to keep your plug in?

The chewing gum must be working.

I checked the new plug on Saturday morning, and it was as tight as when I installed it. Ran the Fall Colors ride, then rode home. Considered taking it to Brainerd, but didn't like the idea of riding home late at night with its stock headlight. Rode to work today. I'll check it again when I get home.
My plan is to ride it until it's too cold to ride it, and then figure out what I'm going to do.
