I've used water for bead setting, when changing tires on the trail.. just splash some on.

Here's another pro for the shinko 244's that some of the x guys use:
they ride flat. You can have NO air in the tires, & they will stay full & rideable. They have very stiff sidewalls, & if you ride offroad in them, you don't need over 10#. I pump them up with 32# for long pavement rides, but let it out on trails. I never worry about flats, now.. i'll just wait until i get home to fix it. It's like being born well hung or rich, except you can buy them!

I take it that you use rim locks?

Counter Sprocket Bolt Remove/Reinstall.

I did some searches both here and using teh Google, but didn't come up with what I wanted, so I apologize in advance if this has been discussed.

I went to remove this nut yesterday, had it in first gear and turned the wrench counter-clockwise, it turned but it felt as if the gear slipped rather than me loosening anything. I looked at the nut and it appears to have a built in cotter pin or circlip type dealio on there. I decided to leave it be until I understand this, can anyone enlighten me? Maybe a link that explains it?

Thanks.

I assume you mean countershaft "nut"???To remove front sprocket??

No, cotter pin or circlip..the nut is "peened" in one spot, where there is no threads. You have to bend out this peended spot, and the nut should come off with a breaker bar.

Some guys have just used an impact gun to remove the nut, although I would not recommend this to anyone, since thread damage could occur.

Yep, counter shaft nut & front sprocket. Would it be better to have it in 6th vs. 1st gear?

Rear wasn't a problem, looks really purdy-like too...

IIRC, I had mine in first, stood on rear brake on right side of bike, leaned over and used breaker bar to break it free.

Type "wr250r front sprocket removal" into Google and the first link that comes up is a YouTube video showing how to remove and replace the front sprocket. Watch that and go and do likewise.

Or if you want to skip the first step, just watch here:

I bought new rubber all round. The rear is 4.00x18 Pirelli MT43 Trials Tire 1347120002(RockyMTNAtv part #), and the front is a 90/90x21 Pirelli MT21 Dual Sport Rallycross - 1035780001.

Not really, I'm just following in the footsteps of others like Ramz - http://www.rickramsey.net/WR250Rmods.htm#tires

It was also discussed a few days back, here - maybe on May 6th as that's when I did all my ordering. It's tall enough to warrant gear changes, so I'm doing that too.
