So because of my hellish work schedule, my poor bike sat from October until earlier this month. We had two guys at work quit and another lost his life in a car accident, so we are stretched thin.

Anyway, a few weeks ago I went to start the bike and it ran sluggish and wouldn't idle smoothly. I sensed bad gas. I decided to tear the carb down, thoroughly clean it, and inspect the parts. Turns out the little rubber o ring in the pilot screw assembly was damaged and some rubber bits had gotten into the pilot jet, and the mangled O ring was partially blocking the air passage from the pilot screw.

I cleaned all that out, and then I also realized that I had never changed out the main jet from when I went from the stock air setup with a K&N hi-flo filter to a Baron's Big Air. I had put a larger main in it at that time, but because of the increased air flow of the baron's kit, I decided to go even bigger. I went from the stock 138 Kehin to a 140 Dynojet before (a 152 Keihin) and ran it that way for 10 years. My mileage was anywhere from 37 to 41.5 mpg and it ran fine except I could tell it was just a little lean at wide open throttle, which i hardly ever got to. Anyway, I went with a 148 Dynojet (162 Keihin) and took it out for a 100 mile spin yesterday of varied speeds and terrain. I ended up with a nice running bike with great throttle reponse and got 45.59 MPG. I am stoked, to say the least. :D

I have a 1500 classic with FI and mine isn't near that high. But, I have straight Cobra pipes, a FI management system and Hypercharger intake. Still, I was hoping for better mpg. I just got it a week ago.

Well, my mileage was too good to be true! the next time I rode it, I did notice an off-idle stumble where from a standing stop it would cough, pop and then take off occasionally, and a slight hesitation at the top end. I suspected the culprit was a needle that was too low, so I raised it a notch. That fixed it, but now my mileage is back down to 38-41. :(

Like I said, small changes, big difference! :D

It does. Though I rarely ever ride WOT, occasionally one may need it.

Well, I'm a doofus. Figured out my 'problem'. I filled up. Had a flat. Ended up running the battery low in the meantime. Well that reset the trip odometer which is what I was using to gauge my mpg. I just realized it the other day because I had filled up again and went out to crank it one day and she didn't want to start (think it's a battery issue). Ended up running it low again which reset the counter again. That is when it dawned on me that it reset. I was almost at 100 miles before it moved off of the F on the fuel gauge. But it's looking like I am around 45 mpg. Now, I am happy:grin2:
