Fuel Starvation at High RPMs
I have a '93 with about 11,000 miles on it. All stock, no mods. Good overall condition.
Having an issue that appears to be related fuel starvation. While riding at highway speeds with a constant RPM of between 4K and 5K, after about 10 minutes the bike will lose power and die. It "feels" like the bike is out of gas, but of course there is a plenty in the tank.
When this happens I pull over and wait maybe 2 minutes then the bike fires right back up. It seems like at those constant RPMs the fuel is being burned quicker than it is being replaced.
Riding around the city the issue never occurs. It is only when riding on highway with constant high RPMs.
What I have done so far (none have had any effect):
1. Rode with gas cap open
2. Removed and examined petcock. Was perfectly clean with no damage.
Anyone have any ideas what could be causing this?
