pd, I hate to ask a silly question but did you try changing just the filter first? The pump on my ride was also howling until I swapped the clogged filter.

Yup.
. Same level of humming with new filter.

pd,
Did the new fuel pump quiet things down significantly? I also noticed no noise reduction with a new fuel filter installed. I have checked all vent lines, fuel lines, filter, etc, and everything looks ok. I can easily blow through both vent lines with the fuel tank lid open, so I'm sure they must be clear. If I can expect less noise out of a new pump, then that is going to be my next upgrade, for sure. That thing is driving me nuts! Next will probably be a PowerFilter too. Scott |

The pump still makes a audible humming sound when I have about 1.5 gallons left. Otherwise its dead silent.
. Yes, the pump has a screen attached to its base.

a pipe without a chip
is like sex without a rubber
You just can't go full speed in total confidence Going from stock to just an induct, thats just not right. All bikes in the US, I mean all bikes are lean from the factory. The damn EPA makes em have to be that way to meet noise and emission standards. The first thing I do to a bike is re-jet or remap (FI) before I would even consider letting more air in. Now add a pipe to the mix, you just have to have more fuel to take advantage of the additional flow. You will not see the advantages of a pipe without remapping the FI, it just isn't worth the additonal $$ if you aren't going to go all the way. Like my mom used to tell me, Dammit Billy, why don't you just stick your head all the way up your a$$, do it right the first time dammit! My mom was a cool lady...............................

Firebolter,
you are probably right about the leaness. On the Aussie models I ran mine for a very long time with porting, InDuct, Foran exhaust and even cams with the stock chip without the slightest problem. Then Epicycle developed the Varireg and I tried it by adjusting the fuel pressure and found that it did improve the overall performance. A little at a time will get the right results.
