||Ethanol additive in fuel is eating up fuel pressure regulators in F.I. bikes...WTF can we do....?
- How did you come to the conclusion this is actually happening in your bike? By: 47Knuckle-Dragger on: 3-19-2011
- had made about a 125 mile run and just before got home, started running bad a missing, suspected fuel problem, pulled pressure line off checkvalve, installed and checked gauge to check pressure, had 22 lbs pressure, pulled fuel pump ass'y in take and could see regulator blown out of plastic retainer. Inquired several places and reputable people I know and was confirmed that Ethanol is raiseing havic on fuel in. bikes. Now I am more careful where I fill-up. Not all stations have ethanol added By: toxandkim on: 3-20-2011
- Interesting, as alcohol has an effect on rubber, but no effect on things made from petrochemicals. If alcohol degradation were a constant then every vehicle on the road that uses any ethanol mix would eventually be sidelined. They're not. You might look a little deeper into your problem, just pointing to the fuel doesn't take much effort in the realm of diagnostics. By: 47Knuckle-Dragger on: 3-20-2011
- I agree with Knuck. I've been working on FI bikes at a dealership for 9 years now, and have never seen a regulator effected by fuel. I have seen some carburetor issues, but the FI system seems to be holding up. BTW, the powers that be are looking to increase the ethanol amount to 15%. By: Guest on: 3-21-2011
- thank-you knuck, will delve further into the situation and see what I can find.....

- Sherlock Holmes once remarked that "When you eliminate the impossible...whatever remains, however improbable, must be the truth." I've been building shit, destroying shit, and trying to figure out why shit don't work since I wrecked my first tricycle. I find that it's never exactly what you think it is; it's never obvious unless the rods are hanging out of the bottom of the cases; it's seldom just one thing that created the problem; you usually have to go buy a new tool to fix it; and that it often catches you by surprise that fixing it the same way over and over doesn't produce a different result.
Fixing something is easy...figuring out how it got that way...is Zen! By: 47Knuckle-Dragger on: 3-21-2011
- I agree Knuck once again...LOL...done replaced, the whole shooting match inside the take now, pump, filter, regulator, and check valve... By: toxandkim on: 3-23-2011
- Guess what, mutha still wouldn't run, bought an electrical service manual and started tested and tracking..when I had the seat off, and many other parts while I was changeing to belt drive primary, evidently had loosen a wire, crank position sensor ground in the harness, and would intermittingly make contact but not enough to throw a code. The obvious is not always the problem and trust in a shop is not always the best solution....Thanks Knuck... By: toxandkim on: 3-25-2011
- Glad you traced down the source of your misery. Electrical problems suck a dick!
I'll have to admit that over these last 30 years Harley-Davidson has tried to make their electrical systems easier to diagnose...even to the point of having them computerized and capable of throwing error codes. Well...except when they don't throw an error code...like in your case. By: 47Knuckle-Dragger on: 3-25-2011
- damn, can't win for losing, went to work yesterday, got a loud rattle and squeal from clutch, pulled clutch plates and basket,steel plates looked gummy, cleaned everything with brake clean and scotch brite, put it back together and works better than it did when first put it together..installed new seals when did the primary, guess i didn't get all the grease off the plates..another lesson learned...
