Excuse the lateness to the party, but I assume a XB9 primary shortens the gearing?

Correct.

Most guys do it for ease of use in the dirt... that way you don't have to use the clutch as much.

I guess that fifth gear with the xb9 primary feels like 4th gear on a stock bike... which should put you right in the powerband for passing

Shortens it up by about 10%. 1st gear on the 12s is way too tall, and doing this only adds about 300 RPM cruising in 5th.

Yes, I deal with alot of hills and slow moving traffic and have to slip the clutch a bit to get going. Also, the bike really feels comfortable on the freeway at around 80mph, about $230 too high

Wow, after following this thread I have hope that I will eventually tear into mine. Splitting the cases looked pretty easy.
I keep looking at replacement motors but I would like to have the satisfaction of fixing it myself.
Great thread and excellent narration and pics!

And it makes it even harder to keep both wheels on the ground!

Parts are coming in fast and furious.



Time to match it up....





Yep, looks like I've got the right parts.

Got pretty pumped up to see it all fitting nicely.



The guy I got the kit from even threw in the locking plate. Nice!

Be careful when installing this nut and washer, the cone faces out and is even stamped on it.



I ordered a new bolt and washer for the crank, even though the guy sent a bolt along, I still needed the washer. The clutch pack nut had to be torqued to 70-80ftlbs. The crank bolt to 240-260ftlbs. My 1/2" drive torque wrench only goes up to 150ftlbs, so looks like I need to beg, borrow or steal one that goes higher. Looks like I've got to wait.

I think I can actually tear it down pretty quickly now that I've done it. I remember you mentioning your bike on badweb. There is hope.

Will do. I've checked out a few of your videos, cool. Saw alot of cool old cars in the "My Commute" one.

Yeah, I live at the bottom of my grandfathers driveway... he had 86 cars in his collection at its peak. Thanks for watching my vids, hope you enjoyed them.

How much do you weigh?

Torque is a factor of work done at a specific length. If you have a 1 ft (or longer) breaker bar, you can stand on it, to get the requisite torque. If you are under 200lbs, stand a little farther (than the 1ft mark) on the breaker bar and you can achieve the proper torque, without waiting...

Just a suggestion.

11% actually, IIRC.

Torque on 08 Engine sprocket Bolt

My 08 service manual says the torque should be 155-165 ft-lbs (210-224 Nm) and to use LOCTITE 271 (red)

The 08 and up models were redesigned to use a bolt instead of a nut.
