    So as my oldest daughter is turning 16 today, limited time was on hand..... But along with the solar panel install, a first start had to be done..... So after the surgery this is literally the first time I push the start.......

    Just had a few minutes to run the neighborhood. No bogging, silly running...etc. This I noticed. exhaust tone is a bit quieter ( I am a bit worried here, as the snappy sound has mellowed) Bike does not pickup as lightening fast as before......but at least in the first three gears are very well behaved. Tomorrow, I will begin riding it, and do a few pulls. It still runs better than stock, but one thing we noticed after the PC-5/AT install, was the snappy sound, like a proper jetted race bike........ Stay tuned. For the record, I am on setting #7. :freaky:freaky

    Ohhh... one thing. I started the bike about 5 times..... And one thing is noticeable, the bike fires in about 1/3 less revolutions..... perhaps half of the revolutions. With this, it is ligtening start, as before it could take about 3/4 second to fire.....

    Excellent report.

    I think you find the 'snap' as the BMSK works through it's adaption process.

    Could be..... I did not reset the adapt. values, so we shall see. It really was twice around the culdesac..... so perhaps it was a bit early......:lol3:lol3

    Do a BMSK reset and take it take it for a ride. During the beta test I could see the adaption continuing for a few hundred miles but the biggest adjustment seemed to be during the first 50 or so.

    Looks like good progress today. You're probably getting the faster start because the BMSK is back to being the boss. It likes that role.

    Keep in mind you're only riding with a 4% enrichment on setting 7. Setting 8 will get you 6% and setting 9 will get 8-9%.

    Setting 7 will work for most but I run the equivalent of 8 or 9 on my bike. Take your time, see what you like best. Nice work.

    He doesn't have a GS-911. Will disconnecting the battery for a few minutes clear the BMSK? Do you have to twist and reregister the throttle?

    I am going to leave the resetting alone for now. Without a GS-911, I would be crap shooting. As it runs good, but not with the power of the DJ, it at least gives a good start, as to avoid the crappy running beginning. I am certain that the BMSK will adapt ok from here.:D:D

    Copy that. It simply sounds like it has less fuel than before. I have tuned many bikes, and have gotten quite familiar with the snappy, crisp sound from a correctly fueled bike. I would say that it just is a tad on the lean side, not quite as mellow as with stock fueling, but somewhere in the middle...... Which is ok, as you pointed out..... I have a few more clicks. I will ride it beginning tomorrow on #7, and see how it behaves.

    The battery have actually been disconnected for 48 hrs, as I had the air box off, so if this is the way to do it..... then it has been reset.....:lol3:lol3:freaky

    I think that will do it!

    Maybe someone else can chime in, but I don't think you need to do the throttle twist procedure like some earlier BMW's to re-register the throttle.

    Yes, it certainly will but the process will be quicker after a reset... I think! :D

    Sounds like you are on that path.

    I dont know for sure, but I think the BMSK would yell at me if something was out of whack..... ( loss of throttle input)

    EB, Based on how setting 7 came up quickly, and your objectives, I think you should go right to setting 8 (or at least go there tomorrow). To get setting 8 (get out your magnifying glass ;) ) and turn the pot counterclockwise one tiny line, which means from about 11am to 10am. Then verify 8 flashes immediately after starting.

    Roger,

    I have a question on the XIED. Does it richen the mixture across all throttle settings? Just curios if it's possible to still run at stoich during steady state cruising for fuel economy, but have richer mixture at both low throttle, as well as when you get on it. Kind of like having an adjustable low speed jet, and an accelerator pump in carb terms? The device has certainly got my interest, now that you guys have educated me, on the limited functionality of the PCV, as compared to how it works on other bikes.

    Jeff.
    The way the XIED works, is that it plugs in between the stock O2 sensor and the BMSK. In doing so it " messages" the signal from the O2 sensor, in this case to make the BMSK think that it is lean, and to add fuel. The thing is that the change is done in Closed Loop. When is closed loop on the 8GS..... I have seen many answers from many smart people, but the answers are not consistent. The way I look at this, is that I can manipulate the AFR control in Closed Loop, and hope there is some adaptation in open look as well.

    Thanks Erling! Cant wait to hear how your works out after some extended use. Thanks to you, and everyone else who's shared there finding on the various fueling products!
