I chose that subject title due to the fuel filter being the only thing I can think of that I've done differently. I've read every post I could find in here on fuel filters, petc0ck, and "reserve", but can't find anything like what I experienced today Here's the story to date. After reading several posts on fuel and fuel filters (Oldfeller's comes to mind, amoung others), and finding it impossible to get anything other than 10% ethanol laced gas in DFW, I installed one of the acorn shaped pleated paper fuel filters in line. I know someone is probably going to ask what kind, and I'm sorry, I'm at work right now and don't have the info in front of me. It was jsut a run-of-the-mill, clear plastic, acorn shaped, pleated paper filter, that I got at Pep Boys. Simple mod, easily done, have run through 3-4 tanks of gas, no problems. What I haven't done since the filter install was switch to reserve (which in past has always worked fine). No other mods. 87 octane. 2oz Seafoam every third tank. 2008 S40 with 1100 miles. Today, I'm running on I20 towards Arlington, doing about 65-70mph, in the second lane, butting a head wind. Traffic's doing about 70-75mph. I start to feel the tell-tale hesitation, along with a visual on my odometer, that tells me that it's been about 100 miles, and it's about time for a fill up. Not wanting to have any surprises, I go ahead and switch to 'reserve". Not even a mile down the road and my bike starts cutting out, backfiring like an LA drive by; and I'm losing speed in a hurry. I've got traffic bearing down on me, so I quickly switch on my hazards, try to manuever to the right hand lane to get onto the shoulder of the freeway (which the cager in the Chevy van to my right took as a personal affront, not wanting to let me in til it became apparant I was going to either go in front of him to the shoulder, or under him), and turn the petc0ck to "prime". It spits and sputters for a second, acts like it's going to catch, then dies. By now I'm on the shoulder of the freeway; only marginally safer than stalling on the freeway. I pull the choke to first position, check the status of my petc0ck to be sure I'm on "prme", and crank the starter til I worry about the battery. Finally it spits, sputters, and roars back to life. OK, at this point I think to myself "Well, I must've waited too long to go to "reserve". I push in the choke, switch back to "reserve", get back on I20, and danged if not 2 miles down the road, it does it again! This time I was already in the right lane, so I quickly dodge to the shoulder, switch to 'prime", pull the choke, and catch it before it completely dies. I'm looking at the fuel filter to see if fuel is getting to the carb. It is, a steady trickle. I notice that as I give it throttle, the trickle increases. I leave it in "prime" and make for the nearest gas station. After the fill up (2.37gal/US), and setting the petc0ck to "on", or whatever the normal setting is called, it runs fine. No problems all the way into work. My question is, would the addition of the fuel filter effect the ability of the petc0ck to get fuel to the carb while on "reserve"? I wasn't able to observe the fuel filter while the petc0ck was on the "reserve" setting, so I don't know if the throttle action was getting fuel to the carb. It definately acted fuel starved, and functioned normally after fillup on the proper petc0ck setting. It also seemed to function properly on "prime". The only difference here, that I can tell, is the bike's behavior on "reserve". From what little I know of the whole petc0ck thing (which is precious little, just what I've read in the posts made here - good info by the way), there should be no difference in the action of the petc0ck in relation to fuel delivery whether on it's normal setting, or on "reserve". Would the fuel filter have made a restriction that the vacuum in the petc0ck was unable ot overcome on the "reserve" setting? Is that even possible? I hate having an already poor fuel situation, created by the size of the Savage's fuel tank, made worse by not having "reserve" as a back up. Anyone got an idea about this? Thanks. Ride safe, Jay
