On my 2010 Z1000, the left hand side rear spool has been banging on the bottom side of the stock muffler when driving down a bumby road.:eek: I read about the possobility of this happening on another forum and checked mine out to see if it had been doing the same thing on mine and sure enough there is a dent in the shape of the spool.
There is simply not enough clearance between the two when the rear suspension is really flexing. But, it does not seem to effect the right hand side. Unless you have really short spools, I would take them off when you are not using them. I have T-rex brand spools and they are not short enough to clear.
Just go take a look at your bike and you will see what I mean.

yea, not a good discovery, Was getting into a habit of putting the bike on the lift instead of using the kickstand kind of making aftermarket cans look a little bit better now

My left muffler was damn close too, so I undid the muffler & the hanger, rotated it clockwise to clear.
Then tightened the muffler then the hanger.
Plenty of room now.
Found if you tighten the hanger first, it just goes back to its original position.

Couldn't agree more Kawtoy...the roads are almost as bad as the crappy weather...

Nobody's made mention of what spools they're using. I got some Vortex spools. Look good, plenty of clearance from what I can tell and work seamlessly with the Vortex rear stand I have. Bring on SPRING!

I posed the following at another Z1000 forum. Bottom line: if you use the Pro-Bolt spools, you don't have to worry about hitting the left muffler.

Any M10 x 1.25 mm spool will fit the threaded holes in your swingarm.

I was using DMP Swingarm Spools that I ordered from the motorcycle superstore. However, the left one stuck out enough that it could hit my left exhaust if I hit a bad enough bump. So I replaced those those spools with ones from Pro-Bolt (Swingarm Bobbins for Paddock Stand - Pair - Pro-Bolt - Titanium, Stainless Steel, Aluminium Fasteners & Motorcycle Bolts ). The Pro-Bolt spools don't stick out very far so there's no interference problem with the exhaust. Just make sure you use thread locker (e.g. Loctite) when installing them. I lost one while riding and had to order a new set! Also, the Pro-Bolt spools are only listed for the '09 and earlier Z1000, but they fit just fine into my '10 Z1000.

Yeah, I forgot about Pro-bolts...good company. I, however, think their spools are ugly as sin...

Good research/find though as an alternative.

I bought a set of cheap Bikemaster spools from Motorcycle Superstore. They're really small, just slightly thicker than the head of the Allen bolt that holds them on. I looked last night and I see no evidence they've been hitting.
