I seem to recall the KLR600 and the XT350 both call for up to 7.5 psi in the forks but that might be a faulty memory. I also remember there used to be a special low pressure pump available to add air to forks. It was thought important to have both forks at an equal pressure. I don't think it will do mechanical or hydraulic damage to add air to KLR650 forks. I think we're talking version 1 forks as I believe version 2 forks don't have this capability. If I was going to experiment with adding air to my forks (and I'm not because I've already tuned them with springs, cartridge emulators and oil) I would probably start with a test ride on a known route. Then I'd add maybe 5 psi and take another test ride. Then I'd add another 5 psi for a total of 10 psi and take another test ride. By the end of the third test ride I'd know whether the air was improving the front suspension performance. If I thought it was I might either continue to add air or reduce the pressure in small increments for best performance for my riding style and conditions. As a side note... maybe a month ago I was helping some friends rebuild some forks from some dirt bikes. We had issues with one pair of forks and couldn't get them apart even after making a special tool. They wanted to replace the fork seals so we decided to try to blow the fork seals out with air pressure. After removing the circlip holding the dust and fork seals in place we added pressure. About 40 psi I think at first. The seals stayed in place without leaks so we increased pressure a few times. After we had 100 psi in the forks and the seals weren't moving or leaking we decided the seals must not need replacing and we added oil and closed them up. The seals still aren't leaking so the replacement was needed. I've heard more than a few times about KLR650 fork seals being removed with about 45 psi of air. I've never tried it. Best,

pressurized. The valves are for the release of excess air generated by heat from fork action during intense riding, as in off road or aggresssive trail riding.

spacers. That's the conventional wisdom, and it's what the manual says. In fact, a number of riders have used up to 30 psi in their forks, reportedly with good results. It would come as no surprise to learn that the factory originally intended those valves to pressurize the forks, back in the days when air forks were all the rage. .
