Skipping while Hot

[BIG--T]

The 98 Standard runs fine the First hour then starts skipping just like clockwork. The filter is clean and I dont feel like the carbs are dirty or it'd do it all the time. The 6-6 Cobras don't have baffles.

Anybody got any ideas?

What exactly do you mean by skipping. If it’s popping that could be vacuum lines cracked. If you are talking about missing. I would be thinking fuel delivery. Maybe the petcock is in early phase of failure.

Which filter is clean?

Like Chrisj said, fuel delivery.

When it's skipping, open your fuel tank cap. Stick a piece of plastic in it (zap strap/stir stick) and close it on it, so that the seal is open to atmosphere. While opening the gas cap, listen for air rushing in.

If no more problem, then you have a kinked fuel tank vent line. Did you have the gas tank off the bike, changing your air filter?

If the carbs are stock, it could be a lean misfire. Open the pilot screws 1/4 to 1/2 turn. If the filter you mention is a fuel filter, they can cause a fuel delivery problem.

If it was running fine before this started happening,

I would suggest to do no adjusting of anything. This is the smart approach.

Then I would look at the things that could go bad like spark plugs.

Also if you just recently made some alterations or adjustments before the problem started,

I would suggest to look there, first off.

Many things to do, before thinking you can adjust the problem away.
