Service manual on page 3-11 specifies a center tie bar torque of 30-33 Ft Lbs. Whereas page 3-27 specifies a torque of 25-27 Ft Lbs. Am I reading this wrong? What is the correct value for the centre tie bar torque?

Page 3-12 of the '09 book says remove center tie bar from engine.

Page 3-24 says "reinstall center tie bar to engine and torque to 30-33 ft-lbs".

Page 3-28 should probably read, by extension, "install center tie bar to FRAME and torque to 25-27".

My read on this is, torque to engine is 30-33 and torque to frame is 25-27.

And I'm confusing myself here...but make sure you're being distinct from 'center tie bar' (the dogbone) and 'center tie bar MOUNT' (the V shaped mount that bolts to the head at one end, and the tie bar / dogbone at the other). I think one torque spec is the dogbone bolts, and one is the v-bar bolts to the head.

My opinion is that some of the torque settings, on the bike, are to high and unless its steel-on-steel I would just use good engineering judgment. 20 to 30IB is close to hand tight anyway. Anymore with steel-on-alloy could strip the thread.

I also think, in part, that this is half the problem with the wheel bearing issue. If you crush the spacer past its limit it will offset the bearing and cause premature wear. The Red seal OEM bearings have been fine for me. 14k front (steering went off at about 12k) and 10k with no wear on the rear but changed them anyway.

All this scary "black art" stuff, of running an XB, that some put up is rubbish. In most respects the XB series are solid bikes and are at least equal to most other modern bikes. They also, if not as fast, handle better than any of them. Thats a fact.
