John, I wonder if you are on the right track? As you know, I also have a Stelli Dan modified tank and have never experienced any fuel starvation problems. There was never any heat shielding with the old tank and all Dan added for my modified tank was a fiber pad on top of the transmission case were very bottom of tank touches, but is to prevent metal-to-metal contact, not heat shielding. Also never heard of any similar problems, even from our guys in the hot southwest. I have been in some hot, 100+ weather, run for hours in the past. Have you checked/ eliminated any of the following; - vent hose from filler neck - is is connected, not kinked or plugged up were it exits down by the center stand with a bunch of other vent hoses. Also, there is a check valve part way down, check that? Not allowing the tank to vent as you draw down the fuel would exhibit the same symptoms you are describing. - the 94's came with a charcoal filter for trapping fuel fumes, but as I recall you had to remove it to fit the enlarged tank. What did you do with the connector hose? - hopefully didn't plug it off. - the fuel filter - that black top hat mounted on the left, by the fuel pump flange is expensive (but can be had from Zanotti's fairly reasonable). Like any filter, it needs to be replaced about every 50,000 miles. - during the rally, the bike missed a few times (very imperceptible) and started getting worse gas mileage. I added some fuel injector cleaner and it ran noticeably better after a tankful of cleaner and mileage came back up. Mexico gas and some of the no name, tim-buck-two, regular only fill ups I did during the rally, I sure didn't trust. Injectors can be fickle things. - Lastly, your fuel pump. It could be pumping, but not meeting spec pressure. Fuel injection systems require fairly high pressures for the injectors to work. I had a fuel injected car several years back that drove me crazy. It had spark, gas was pumping, but under load or acceleration would start missing and bog. Turned out the fuel pump was worn out and not delivering enough pressure (and it was in the gas tank- what a job that was). good luck, -- Dave Biasotti // Fremont, CA

When you ride thousands of miles on a malfunctioning bike, worrying that it may quite anytime, you have plenty of time to contemplate more than your navel in looking for solutions. I think any heat shields that may have been on the tank, were removed when it was rebuilt. It is something definitely needed and which I will install. I would warn everyone though that the strainer is a real potential restriction on the GTS and a very real potential problem. It can aggravate and make altitude and heat the final straw, as I found out. As I was topping off the gas tank in Salt Lake City, a guy in a car walked up and we started talking about the vapor lock problem. He owned a Kaw and said he had to remove is lower fairing to stop a vapor locking problem. They talk about dry heat being tolerable out West, obviously whoever says that has not driven a motorcycle in early afternoon on the black asphalt interstates there...it is hot. When the GTS vapor locked climbing out of Salt Lake, the Highway patrolman stopped and helped me push it a couple hundred yards to a rest stop to get out of the traffic. He wasn't even breathing hard and I was sure my lungs were going to start to bleed as I gasped for air. Anything I can do to keep it from becoming a problem again is open for discussion. hawke On 6/22/02 1:04 PM, "Rev.
