You know, more I think about it - you have air pressurized forks with air over oil, not sure why it shouldn't be OK in rear shock? May not be perfect factory performance, but for light weight trail riding probably never know the difference.

got info, please share..
This is true. The bladder takes up more then half the space in the shock. So other then heat maybe having a small amount of effect in changing the pressure a lb or 2 I seriously doubt oxidation ever really becomes much of an issue.

Here's what the bladder looks like.

Yepers, I thought it was pretty high!

While setting up my bicycle I noticed the fork pump goes to 200 psi, and theyre designed to not let all the air seep out like a regular tire pump or chuck when you remove it. Come borrow mine, the gauge is stuck on 50psi for some reason, I'm headed to buy a new one this morn just to be sure im accurate. Albie def had a good idea on the pump.

I think the main reason to use nitrogen is it doesnt fade. So if you're out there racing lap after lap your suspension stays consistent. Playing around in the yard you guys will be fine doing whatever. As long as the shock is working properly and the rear isnt bouncing and the rebound is working (not coming up too fast) you guys will be ok. You never wana ride one with a blown shock and a "springy/bouncy" rear, as it will send you over the bars in quick order.

Hmmm I imagine if anything regular air as opposed to N2 would make the shock STIFFER when it gets hot, not make it fade. The air is only there to create pressure in the oil reservoir. When air heats up the pressure RISES. Anyway, considering the very small volume of air used, even at the hottest temps you wouldn't see any significant rise. And remember that air is almost 80% nitrogen so only 20% of that volume is going to be effected by the heat.

the funny thing Albie, from reading on thumper talk and other places on the internets, people are saying it will explode, impale, and maim you.

its quite amusing!

How hot woul I have to heat that small volume of air at 30-50 psi to get it to pressurize that bladder higher than the 289 psi of nitrogen its designed to hold?

Im thinking 1200 degrees? haha

Bluhduh clutch

I think I need a new clutch pack. My bike is lurching/dieing when I first put it in gear after a cold start.
I guess I can order that when I get my upgraded fuel filters.

I think I've read about folks taking it apart
and filing the lugs on the clutch basket to fix that

like they wear an irregular notch in the supposed to be flat lug area and they can't completely release

Notice the guilty "Sorry pop, I opened one of your boxes" face.

Dang you for putting your kid daughter in the pic and ruining all the fun... Suddenly all the jug jokes I was going to make are a whole new level of inappropriate.
