Head Bearings and Axle Flip
Well, I dropped the big girl off at the local bike shop yesterday to get the new steering head bearings fitted. While I was there, I asked the owner, Tom, about doing an axle flip for me. Tom knew of the mod and happily agreed to do it for me.
Side note for those who don't know: The ZX axle sits in a cam on each side, for tensioning the chain. Turning the cam moves the axle, which tightens (or loosens) the chain. I'd heard about a simple mod of turning the cam through 180 degrees, which moves the axle from the bottom of the cam to the top, lifting the rear of the bike. This, in turn, increases the rake at the front, giving the bike a sharper turn in.
So, this arvo, I popped back into the shop to pick my bike up, everything done. First thing I discovered about the axle flip is that the back tyre now touches the ground when the bike's on the centre stand. Hmmm, that's going to make chain work a bit harder; I'll have to put a board under the stand now. I also discovered, later, that she leans a lot more when on the side stand now. Stand extension or live with it???
After a couple of goes, I managed to get the bike off the centre stand. I used to be able to rock the bike back, then push forward. With the back tyre on the ground, I can't do this anymore. The seat's now about 3/4" higher, but I can still flat-foot, just. Pushing her around while seated is going to be a little harder.
On the road, the difference in both the bearings and the axle height was instantly noticeable. The smallest bar input is rewarded with instant bike movement. It's only a short trip from the bike shop to home, but I was smiling by the time I pulled into the garage.
I'll report more after I've done some k's....
