K11 forks & fork oil question

[basketcase]

It's time to do the fluids change on the K11, and after reading a bit on another site, I am wondering:

1. What is the deal about Showa forks? Specifically, how do I know if I have them, or not? And, if I do, what special steps do I need to know about for this task?

2. Oil type. A local motorcycle shop carries several brands of fork oil in a dozen different weights. Which brand do you prefer?

3. Viscosity. Following up on question #2, what weight of oil do you prefer, and why?

Thanks,
Rick

I had a '94 K-LT. Doing the forks isn't a big deal, unless you've never done them before. The Clymer book is prety good about it. As far as oil, I used 10wt PJ1, because we sell PJ1. 10wt seemed to be a little better, IMHO, at keeping the front not so busy. It could've been just the new fluid, too. in any case, you might be better off removing the fork legs one-at-a-time, disassembling , cleaning all the crud out of the slider, replacing the seal, and reassembling with the new fluid. BTW, before removing the fork leg, while the upper clamp is still tight, loosen the cap somewhat. It's a whole lot easier when you'e got something to hold the fork tube, like the upper triple clamp. Also remember to use a torque wrench when tightening the clamps.

Are about installing the new fluid.

Rather than disassemble the forks, can't I just pour it in (via a funnel and tube) at the top?

Also, is it necessary to pump the forks as with the older K models?

TIA,

You can do that, if you wish, but you'll need to pump the forks whild draining them to facilitate draining. Just removing the drain screw and the fork cap does not ensure getting all the old fluid out.
