Rear shock & nitrogen pressure

 

I've got my '99 YZ torn down to the bare bones right now. I'm staring
at the shock exposed since I removed the subframe and thinking it's
probably time for a rebuild. I've had the bike almost 8 years and
never done anything for it, other than replace the mounting bearings.

Hmmm, a schrader valve... Figured I'd test it to see if there was any
pressure in there. Got out the tire gauge we use for road bike tires,
it read 82 psi. I'd done a little research, seems that 135-165 psi is
the going pressure. Aha, low! Definitely time for service.

I look over at the 2 other, newer, YZ's sitting in the stable, quietly
minding their own business. Hmmm, I wonder, what pressure THEIR shocks
have???

So I checked, with my handy dandy bicycle pressure gauge. This one:

They were both at 105 psi.

I did a little more reading. I think I've probably released a
significant amount of nitrogen by simply checking it with a tire
pressure gauge. Anyone have direct experience with nitrogen pressures,
and the best practice for checking, on a dirt bike shock?

I'm thinking I'm going to need to top up the N on both shocks while I
have my '99's shock serviced.

you found out prior to going riding. :-)

I just dropped the FZ1 shock off at Phil's house.

Well, at least my foreshadowing worked <g> I can use rmd to hone my

Too bad my memory is so bad. google found a discussion about this very
topic almost exactly 2 years ago.


I gotta talk to you about Mr. Douglas.

I hear some kid from phoenix tried topping his shock
off with the oxy acetylene tank in his dad's garage....
