SCTA Motorcycle teardown?

[AlanGalbraith]

Heard me a runour you are now required to tear down after backing up your first record of a meet, once certified cc wise you can then seal the engine and go back out to run...

is this true?

[Larry Forstall]

Yes. Eliminates the final day backlog of certification and the chance that an illegal entry could cost someone a record if not found illegal until the end of the meet.       Larry

Last year at SpeedWeek there were a couple of signs posted at the Motorcycle Tech trailer area:  Get a record today?  Get your motor measured today!"

It was signed with lots of X's and O's by Tom Evans.  I think they were X's and O's.

I was starting to get depressed, then I remembered y'all with metrics....

[JackD]

The bikes should never be treated any different than any other entry for all the same good reasons.
 If they have the luxury of an accurate way to measure the motor without removing the head, the obligation to make that available to everybody is very important.
 Sealing should reflect the requirements of the meet and be with out exception the same for everybody.
 The further you stray from that, the sooner you will find yourself on the outside looking in.
 Don't ruin it !

Not trying to stir anything up... just asking a question, so if I go to a SCTA event, I know what to expect.

I'm golden any way you look at it.. 2 strokes, flatheads and single cyl pushrod motors for me.

Teardown? 40 minutes start to roll it back to the trailer and go get in staging line.

[JackD]

Keep it simple and that makes more time to enjoy it. Conditions are less important
 to somebody going 150 instead of 250 and more racing can happen.
You are less likely to be the focus of the politricks and the victim of them also.
Can you imagine the problems the M class HD bikes are facing ?
And that is not all of it.

[Hans Blom]

is there a specific reason they require us to teardown and not cars?

[dwarner]

Cars are measured with either an air pump, direct measurement dip stick if a center plug head or as a tear down as a last option.

If your bike can be measured with air, oil or dip stick I think you are Ok before having to tear down.

Oops!   said too much, I promised not to butt in on bike stuff.

Yup, Dan -- bikes CAN be oil measured.  Mine's been, many others have been.

It's okay if you talk about bikes once in a while.

I didn't really need to post, but my totals getting near 4 figures and I want to be in that exclusive group.

[JackD]

The dip stick and oil CC method were developed by the bikers before their use on cars to minimize down time.

[Hans Blom]

So does this mean there ISN'T"T a mandatory tear down, assuming an oil or air pump test indicates a acceptable volume???

[Seldom Seen Slim]

In direct answer to your question:  Yes.

Measurement is mandatory (to certify a record) -- how they accomplish it varies.

If air or oil pumping shows an acceptable result a mechanical measurement requirement may be waived.

I don't think offering beer to the measurers is a help, but I do know that, upon hearing that the easier method has produced an acceptable result, an exclamation of astoundment (by the racer or his mechanic) might bring the measurer to decide a more careful measurement is called for.

If you know what I mean. . .

[Seldom Seen Slim]

Hey, is the points-counter-upper broken?  I just looked back at the last four posts I've made -- each one shows me with 983 points.

Jack, did you break the machine?

[dwarner]

Jon,

Reveals the value of your posts  

For Hans,

The sign on the motorcycle tech trailer at Speedweek last year said something like; "set a record today, certifiy today" not set a record today, tear down today.
