I have a 1980 Flyer transit that I have owned since '98 and that I drive a few thousand miles a year. It developed a fuel leak and I decided while I had the pump out to fix the seal, to have the pump man turn up the rpm as the head mechanic at Seattle Metro where I bought the bus from told me it turned 2050 which results in 60 mph. When I picked up the bus, he assured me that it should turn 2 or 3 hundred more rpm. When I took it out on the freeway, it ran the same as before, 43 in second, and 60 in third. It has an air throttle and it is either on or off but it seems since the pump work that I have to take my foot off the throttle almost all the way before it drops to idle speed where before it would drop down to idle as soon as I lifted my foot a small amount. I don't know if that would indicate that it is turning more rpm or not. Is there anything in the transmission [V 730] or in the pump that regulates the speed? I realize that these are probably silly questions, but I want to get my facts straight before I have a confrontation with the pump guy. Without a tach there is no way to tell the rpms, only can go by the speed which hasn't changed. I had been led to believe that an increase in rpms or a change in rear end ratio would result in more miles per hour, so I'm thinking that they didn't actually recalibrate the pump as they said and they charged me an extra $125.00 for, but without a tach I really couldn't prove it. All I know is it still is chugging along at 60 mph for a top speed. Any ideas on this subject would be greatly appreciated as I am in Jackson, Tennessee and I have to leave to go to South Dakota in a few days and I need to get this situation resolved before I leave.
