MessageThat goes back to what I was saying in a past post that the best gas is 
Shell or Texaco.
By the way...I just used some Lucas treatment in the gas for my "new" 88' 
Cadillac Sedan Deville. I was impressed with the performance. Has anyone here 
used it in their bike?
I also see that Lucas oil is suggested for bikes. The claim is that replacing 
part of regular oil with Lucas extend your oil performance (they say double 
it). Has anyone here had any experience with Lucas oil?

        I can only speak of my area (NE PA) as gas is formulated differently 
for others. State laws, and temperatures affect this. The Shell stations here 
have no alcohol at present, most are at 10%. GA allows 10% to be added at a 
distribution point. I once got a load of 30% on I-95 in GA and had some real 
problems with it. Doing a water separation test can determine exact amount. The 
alcohol causing some parts to swell will be a problem as the percentage 
increases.

          Dennis,

          Are they putting Ethanol in all levels of gas at the same percent?   
I run premium in my bikes and I'm wondering if I'll have this problem.

                  What wonderful troubleshooting you do! You've diagnosed your 
own problem. The gas cap is not venting properly. I saw this Tuesday on a Honda 
GX340 mounted on a septic tank cleaning truck (crapper) The air lock causes a 
starvation after a few minutes. I replaced the cap and sent it on its way (none 
too soon, phew) The cause seems to be the increased alcohol in fuel now. It's 
causing a swelling of the gasket that seals it to the tank. The swelling closes 
off the small vent. Replace the cap or... One cure I had for a bike that I 
couldn't get a cap for was to put a "tee" fitting in the fuel line and run a 
translucent hose (gas resistant) under the tank and up to the fork nut. That 
put it above the fuel level and supplied a vent. Leave it open at the end or 
cap it, just remember to drill a small hole in the cap. Being translucent, it 
makes a gas gauge too. (Hey Kyle, remember that from your X6 ? The gas gauge on 
the left side of the tank) I suspect I'll be seeing this more often in the near 
future as the E level increases. For now, when you feel it going down, open the 
cap for a second or two.

Hi All,As the message header indicates I'm a recent addition to the 
nighthawkgroup, new to nighthawks and new to riding. I own a 1986 
450,namedJenny by the previous owner,  that I picked up here in the L.A. 
areawith a questionable 18k on the odometer. Questionable only because 
thespeedo was swinging like mad on the test ride and stopped workingcompletely 
a week or so after I bought it. I now have about 200 - 300miles on the bike, 
and things have been going well.I've learned quite a bit since I've been 
lurking here ( the tiresaren't quite as new as the previous owner stated, that 
clunk intofirst is somewhat normal, battery care etc) but I've come across a 
newproblem. I set off to work this morning with a detour to the gasstation (1.5 
miles tops) to top off my front tire when the bike stallsat about 40 mph. Feels 
just like I ran out of gas (tank
 filled thenight before). I checked the petcock thinking I had forgotten to 
turnit on but it was good. I switched to reserve, no dice. I spent acouple 
minutes rolling off the busy street,parking etc, opened my tankto make sure I 
wasn't hallucinating about the full tank. I figured onemore try before the walk 
of shame home, and the bike fired up with alittle sputtering and then proceeded 
to run fine all the way to work( ~20 miles @ 35 mph)So, onto the ride home. 
About 20 min. into the ride at ~40 mph I feelthe bike start to stumble, I reach 
down and switch to reserve thinkingsome sort of blockage on the intake, and it 
clears up. Another 10 min.down the road a big stumble and several stalls from a 
stop ( being anew rider I assume with my fingers crossed that it is me but 
thatwears thin with the third stall). Repeated starts and stalls,switching to 
reserve and then it clears up for another 5
 mins. Anotherstall and this one lasts about 5 ~ 7 minutes, the bike has been 
onreserve since the last stall. Playing with the petcock again, openingthe tank 
and resting and the bike fires up and I ride the last coupleof minutes home. 
The last clue comes as I shut the bike off and startto back it into the 
garage-- I hear a faint hissing sound and itscoming from the gas cap. I open 
the tank and there is a hiss as thepressure equalizes(in or out I don't know). 
Mind you its only beenabout 3/4 to a mile since I last opened the tank. So, my 
guess is somesort of fuel system blockage/slowdown that starves the bike for 
gasand then manages to clear up. I have decent car repair knowledge butam new 
to bikes and am hoping for a few pointers. Thanks for takingthe time to read 
this far and for any help you can offer.Joe in Altadena
