I'm totally slacking.  I'm between jobs for a week and on vacation, I'll get back on tis when I get home.

Bob, all the looking around the web I did said that MAP is less sensitive than MAF, so much so that it's often preferred for performance applications where MAF falls short.  That said, it's all theoretical right now and I'm sure individual application can vary which is why we just need to mount one of these up for a while and see what happens.  As soon as I'm done with vacation....  ;)

I love the inventiveness and the willingness to experiment for better or worse. I would also like Scotty to explain the word "vacation", it is not a word that either Scooter Bob or I  am familiar with.

FYI - We also have put together a low restriction air filter. For sale soon

Sounds great!  Another way to spend money!!   :D

How will a low-restriction air filter jibe with the upswept or EFI silencers, compared to the stock torpedo?

Vacation - Quitting one job and getting another, realizing that your wife is right and you should take a week off between the two because you don't want to take the toxic attitude with you from the old to the new, not having any money but saying, "Screw it, let's just credit card it because I need to flush 2 1/2 years of professional poison out of my system."

My bank statement says I can't afford this but my soul says I can't afford not to.  The last time I took more than a day off to go away and wasn't seeing family was 5 years ago for my honeymoon.  Oh, and my wife deserves this more than I ever will, she's the best.

Kevin, did you also try the air filter with a open pipe like your megaphone (or an open pipe with the stock airbox)? I experienced a lot of running problems with the RE megaphone installed (stock airbox). I had to take it off and put on the more restrictive EFI and 90% of my idling, stalling and hiccup problems immediately went away.

Interestingly none of them are approved for road use. I guess they make more noise than your neighbors can handle.

Back from vacation, a huge success!  While away I talked my wife into letting me feed my 10 month old son pickles, bacon, and the best poutine in Vancouver.  Now back to motorcycle projects...

Today I picked up the upswept muffler from the Seattle dealer and will put it on this weekend.

So I got to wondering about the the upcoming low-restriction air filter.  If the EFI mapping is as wide as stated, what will be the advantage(s) of going with the new air filter? 

Heh, history is repeating itself here.  I did about the same upgrade stuff to my '78 SR500 (the first year it came to the US), also black.  Thankfully, the upswept muffler is less noisy than the White Brothers Supertrapp pipe I used.

Yup, less restriction at either end means more air flow means more power.  If the map can provide enough fuel you'll be good.  If you don't like the exposed filter thing there are two filters from K&N that can should fit in the stock spot, I'll dig up the part numbers later.  And Bob mentioned a more free flow filter coming soon from CMW.
