I did the 1,000 mile service myself yesterday on my 9. Everything seemed basically fine. A couple of small things needed to be looked after. The primary chain slack cold was around 650 thousandths. The cold range is 375 to 500 according to the shop manual. I set it to around 425 using a machinist's scale. Anybody else (Bubba) have theirs that loose at the first service?

I had a bit of oil weepage at the oil cooler fitting & gave it about 1/16 turn tighter.

Crankcase oil was quite dark and the magnetic drain plug had a tiny amount of debris on it.

Tranny oil was also quite dark and the magnetic drain plug had fair amount of slivers on it. No big pieces though! That reminds me - there seems to be a false neutral between 3rd & 4th (might be 2nd & 3rd). I've run into it maybe once or twice when downshifting with the bike stopped. Anybody else experienced this? Sounds ugly when it happens. No big deal though.

I put Amsoil synthetic in both & I honestly haven't noticed any difference yet in shifting or fan run time.

All things considered it was an easy service. Nothing an average wrench couldn't handle.

Before a primary adjustment, never after one.

Glitch - Cool, I don't quite see the connection there, but maybe I fixed it with the primary chain adjustment I made.

Since I put some Mobil-1 gear oil in I haven't had the false neutral and loud CRUNCH when I shifted out of it.

Yep, the false neutrals and clunking shifts get better over time and get way better when you switch to synthetic.

These bikes don't downshift very well with the bike stationary, best to do it while slowing down. When these bikes are new the primary chain will get a bit loose between services.
Good on ya doing your own service, one less dealer complaint for the BWB Board.

I have to downshift with speed according to gear.... 4th at 40 mph, 3rd at 30 mph, and so on. If I roll up to a light in 4th and stop it's not going to go into first gear. Best bet is to shut the bike off before you get the loud BONK.

If I have to stop to quick to be able to downshift correctly, I can get it down to second then it doesnt want to shift down through nuetral to first...so I take off in second...A little feathering of the clutch is all it takes, but then again its not like I don't have the torque...then I usually try to get around the idiot that made me stop that fast as soon as possible. Seems to generally happen as someone zips out of a parkinglot right before a stoplight as it turns yellow...something you are generally going fast enough that when you hit the intersection it is still yellow...then the idiot hits the brakes...sighs...I am so frickin' tired of that...

I have ridden a FatBoy in the past for a number of years and recently got an '03 XB9R. In both cases I have found shifting into or out of 1st gear is "picky" and if done incorrectly a seriously wicked clunk can occur which makes me wince sometimes!

Generally I do not shift into 1st unless I am going less than 5 MPH. On the upshift I need to shift at around 5 as well or make sure the timing is right if I go faster (not too fast and not too slow due to the flywheel).

I have never understood why 1st gear has to be so low given this is a torque motor...I think it needs to be about 1.5 or 2 times as tall and then bump up the rest of the gears so their ratio is the same as it is now. These motors can pull that no problem.

If you launch just right you can get to full throttle for just a little bit in first. Also, first gear is only useful on a track when you launch (except for maybe Monaco)so it should have a lot of acceleration. From what I can tell this bike is setup for performance as opposed to spec sheet numbers. Well done Erik.

I hear you though... I just think that the better solution would be a six speed with closer ratios on third through fifth and set sixth for about 175. I know we wouldn't make it to 175 w/o VERY SERIOUS modification... but it would give us a good cruising gear.
