Actually it looks like Bill beat you by 13 minutes.

Rmember, not only did he have to type all of that, but he had to THINK of it too.... im sure he started that post well before Bill posted his.

Yeah, you're too smart for me. I was just copying what Bill said and I have no idea what I'm talking about.....

You are right Steve, but it is me not Matt that is slow in reply.
It often takes me a half hour to post. And yes, our posts crossed in the intertubes. I was editing mine as Matt posted.

Sorry Matt, It's a tough crowd. At least we answered the question.

I think slowly and type fast. Bill thinks fast and types slow.

No problem, Bill. Like you said, at least we answered the question.

I think it is the dialup that is holding bill's posting speed back. I had forgotten aobut that.

And yes, sounds like you guys answered the question, and I learned something in the process.

Yes - exhaust bridge. Needs relieved for heat.
Wiseco did the same procedure for my CR500 cylinders.
Little late on the draw -- looks like you've got it covered.
A good book too:

Millenium was very appologetic and had it sent back at cost to them. I should be getting it back in the next day or two.

[lucky13]

Sweet.....any mention of how it got out the door like that?

Nope, just that "it should never have gotten past QC like that. They included a shirt and stickers when I got it back this time.

Cylinder looks great, measured it and the spec was exactly what it was supposed to be: 44.50mm

Broke it in and was riding on saturday. The bike was still breaking up in high RPM. Looks like everyone missed the cause, the spark plug was a little too worn. Threw in a new one Marc had and it worked flawlessly.

Well, right on! Gotta love it when the fix is the cheapest part of the entire bike!

(note to self: keep extra spark plugs handy)

That's what you get for asking advice from a bunch of dummies.

Pretty standard to install a new plug when doing any trouble shooting, and certainly when you rebuild the top end

That's odd, you were the third person to post in this thread and I didn't see you mention anything about trying a new plug on for size. Miraculously his crank/rod seems to be holding up just fine, though

Just be happy for the guy. His bike is back in action and he can race again. No harm no foul.

[Steve-o]

I never put a brand new plug in for break in... I always get a couple heat cycles on it then put the new plug in.

[fireman_343]

Spark plugs... do these bikes take them?? I thought it was a diesel!

Glad you got it back together and on the track again.. see ya at the next race!

[teddy]

HMMMMMMMMMMM everyone I know that rebuilds 2S motors uses a "basic" new NGK plug for heat cycles then installs a New high end plug of their choice..... Plug inspection between each heat cycle if possible...... certainly after the motor is back together...... I mean thats part of building and maintaining a race bike right?

BEDIT: (Jordan) your killing me, I would ASSUME one would try a new plug if the bike was running poorly. Like the other month...... when that does nothing look further into the problem..... carb......... seals.......... spark.......... oh gee it needed a new top end?

[ExSRAaron]

yeah i said sparkplug! prolly as u were cleanin' ur old one HAHA! glad its running good...it was pretty fun watchin' u guys battle back and forth on sat, all the way till the lowside-endo-backrest event.

Chill, I have never had a 2-stroke before so I asked on here as there are people more knowledgable than I about this subject.

Yeah more to that story... I had clear liquid come out my nose when I bent over to look at the bike, and still had that headache. I didn't think much of it but told the GF about it (a doctor) and she started freaking...I guess headache+hit to the head+clear fluid = good chance of a skull fracture so I went in for a CAT scan. There didn't find anything but it scared the GF pretty good.

[fireman_343]

Yep... clear fluid and a head-ache are signs of a possible skull fracture! Also, bruising around the eyes is also...? If I remember from my medical training.. I need a refresher on that stuff!!!
WOW, didn't know you crashed last weekend and that your GF is a Doc!
