Head shake/tank slap?

[Lester532]

The front wheel axle torque is 48 foot pounds.

It's not really a lot of torque. Do you have the spacer installed on the right side between the wheel and the right fork leg ?

This might sound real stupid but I have found with a little steeper pitch on my windscreen it makes it a whole lot smoother some ****** rockets have that trouble and they have a stabilizer shock on the front forks

After having the front tire off and on several times, I'm having trouble understanding...the axle bolt, when tightened, pulls the forks together against the spacers. Then the pinch bolts hold it there. Maybe what you are saying is that I may not have torqued my axle bolt tightly enough. If that's what you are saying, that would make sense. A loose axle bolt might allow the wheel to "wander" enough to cause a high speed wobble. Sounds reasonable. Anbody got a quick reference to the shop manual to tell me the torque spec. (in foot-pounds)? I've cranked it down about as tight as I can with my standard socket wrench. Maybe I need to torque it some more with an 18" breaker bar instead. Sure couldn't hurt a thing. Be very funny if that was my trouble the whole time, huh!!

the front axle beds by threads on one side only ... this doesn't take up lateral free play on the spacers as such. you must 'drift' the pinch bolt side over to take up any remaining free play that is left to eliminate any oscillation .


this applies to standard & classics R-3's with "upside down" slider configuration.

I'm not familiar the touring fork. Is this what you have?

I probably over-torqued it...guess I'll back it off a bit, then drift-punch the forks closer together before tightening the pinch bolts (like Goodfellow said). I have spacers on both sides: the flat spacer on left, and stepped spacer on right. The spacers are pretty idiot proof: they only fit one way. Don't think even I could screw that up, LOL!

I took my shield off last April when the weather turned warm, and have not yet put it back on.

Still trying to figure out the head shake....Took off my new front tire today (Shinko), and reinstalled my old Metzeler. I am 95% sure the shake is now gone. As a result, I now think I had a bad tire. Ordered a new Metz tonight...guess we will see for sure when I get the new Metz mounted and balanced.

Anybody want to buy a nearly new Shinko? Runs real good up to about 80 mph or so!

Geezzz for the price of the Shinko it shouldn't be bad! lol

Just a point to ponder I have almost 8000 miles on the front Metz that came with the bike. I don't know if that's exactly good or not but I guess that could be the shake I'm getting over 100 MPH.

Did you ever try a typical balance? Having weights on your wheels is a small price to pay for a smooth ride.

head shake

cw,

if the new tire doesn't help then try a heavier oil in the front forks... 15 weight is a good starting point.

Gotta confess: I also ordered a balancing station and some stick-on lead weights. I'm not totally sold on the Dyna Beads. I am giving some thought to trying Dyna beads on my new Metz just to see, then switching over to lead if not. Don't think I will, though. I'm tired of taking the front wheel on and off and on and off and on and off. Have to admit, I HAVE gotten pretty good at it, though, LOL!

But this time, I'm going with lead weights, and (hopefully) be DONE with it!!
