knee pucks

I have been working on my body position and maintaining weight bias on the bike lately, but now im putting alot more weight on my knees and im just frying knee pucks left and right. Is this a unproductive way to ride a motorcycle? Should i just start running ceramic knee pucks? I have poised this question to quite a few riders, but if anyone has some input or some suggestions it would be greatly appreciated.

I have been flirting with that once i get the bike settled. Let me ask another question. Does having some of your weight planted with your knee help the bike handle and provide a little more forgiveness when you have a little hiccup?

ur making it sound like if ur taking enough weight off,to take the load of the shock.....
just how tall are you?
once i start rubbing the puck i raise it off and only use it as a "lean indicator".(little to no weight)
i would think if you get too much weight off the bike on an off camber turn you could loose valuable traction.

Nope. Im 260 Stock suspension, running 56 at TWS (Texas World Speedway), ran 6 TDs on my pucks and there are plenty of life left in them.

Rebound on the rear shock. It is tearing the out of my rear tire. I finally invested in a Penske Double Clicker and will have it installed next week. Hopefully that solves that problem.

yeah? that seems to be a pretty common problem for everyone. You guys have definitely given me some things to think about. Looks like i got some more practice to do.

I'm about the same size as you, but I do not plow my knees into the ground. I skim the surface a little, but rarely put any pressure on the knees.

I'm thinking that by pressing hard with your knee, you might be taking load off the tires, thus reducing friction between tire and pavement. I also noticed that the harder I press into the ground with my knee, the harder it is for the bike to turn.

My biggest problem with stock suspension is the front spring. I bottom out the front on occasion, so I need to fist this fast, prefarably before next time I go out on the track.

If you guys have set your sag properly, and your suspension is still mechanically bottoming out...then you need to switch to a different spring rate...they are too soft for your body weight.

In that case...springs arent cheap, so might as well revalve and spring the rear shock, or do like AJ did and buy an aftermarket shock.

Before adjusting your rebound or compression...I highly recommend getting your sag set properly for your body weight. It will take a couple buddies, a tape measure, all of your gear on, feet on the pegs in your riding position, and maybe a c-spanner wrench.

Your bike should show free sag. If you sit on it...get it adjusted so that it sags about 1 inch (for track) with you in full gear, and it shows NO free sag (and its topped out), you need to go with a higher spring rate...that spring is too soft for your body weight.

Once you get your sag set properly...then map your rebound and compression based on feel. You can get close by eyeballing rise and compress rates on a wheel chock or just standing there pushing on the bike. Then...ride...focus on the feel and handling, and make minor adjustments as needed till you dail it in.

You should not be resting your weight onto the ground through the puck. Like others have said, you should be skimming it across..picking it up...skimming...pick it up.

EDIT: Also on some bikes the rear shock rebound adjustment is backward meaning that the H and S settings are reversed. Effectively to increase rebound rate, you "open" the valve (which would be turning the screw out), but some bikes have the H for a harder rebound rate on the direction in. Dont know why...just have noticed that on some bikes.
