Assuming no air leaks, the ecm could be adjusted in the fuel bins at TPS = rolled off. More fuel or less fuel say 10% should stop popping. Even though its an 08 model, ecmspy can download the eeprom and you can "burn changes only", or if its an early 08, ecmspy can edit the fuel maps directly.

Dannybuell are you running a stock pipe? The flat spot at 3k - 4k, I thought that was standard, well it came standard on the only test ride of a new stock XB9 I ever did, but maybe yours is worse than that. Dunno.

Hi - picked the bike up - massive improvement - runs superb - well only done 60 miles.
They didn't charge anything ( warranty) and they now provided me with an electronic print out of the settings - the TPS was 46 when the max setting is 42 ( I really don't know what this means - i'm a centigrade guy - 0 or 100?).

I will keep you informed.

Also I think they read this forum - a bit better response when I picked the bike up.

thanks for all the help and comments.

my mind goggles reading the techi conversations you lot have.. i so wish i was technical i try to follow it and ive read some of the how to stuff but iget half way down a page and am like errrrrrrr am sorry what! and there u are am lost! I used to try and follow stuff my mates do and i do still try and listen now but am afraid most of it just goes over my head and it sucks coz i actually want to no stuff.... theres nothing worse than people talking about bikes and presuming (rightly I know that coz am a woman I no fuck all) you either get one of two reactions when walking into a bike shop/garage as a woman either everyone is bending over backwards to try and help you or everyone treats you like a c**t and to be truthful I dont no which is worse

It's not just women that get that. Although I do (usually) deserve it.

oh ok ill shoosh now then lol

i have an xb9 same year as yours ,mine also has a flat spot between 3 n 4 thou . took mine back to the dealer twice ,first time they said they sorted it so i rode home and it did it again ,took it back they said there was nothing wrong with it and to add insult to injury they said it was the way i was riding it (bullshit)so you cant open the throttel hard in 2nd gear between 3 and 4 thou , the service manager asked me what i rode prior to the buell i told him a 1975 xs 650 ridgid chop , ah said he that explains it the xs has more tourque than the 984 cc buell bollocks said i , his answer was to knock it down a peg before accelerating so that is harley davidsons service managers answer. cant do white wire mod so until there is a mod for this you just gotta live with it . although fitting a race pipe (home made by the way )and a k&n has helped a bit i also ride it a bit harder and havent had it happen recently. (there are some photos of my can on the events and rides part of the forum taken by cj at squires cafe meet in september .check it out !)
