 LOU--how much tread you got remaining on those tires.  Very few 
 people get much more than 3500 miles out of a rear tire.  Maybe a 
 little more out of a front tire.  REMEMBER:  a motorcycle has very 
 little tire on the road--make sure that tire has some tread on it!

Ross has an excellent suggestion; make it a HD tube.  What has not 
 been said here, is 'air-pressure'.  The OEM book suggest something 
 like 21F/24R--which is scary low if you are very agressive on the OEM 
 tires. THe lower pressure is 'average'--when was the last time you 
 were an average rider. smile.  21/24:   Can you say, 'slide the 
 tires'--it will scare the crap out of you when the tires slide and 
 you are not expecting it.  Pressures closer to 30F/32R or +/- a few 
 lbs.  I run 32/36 asphalt with a loaded bike or 24/28 for softer 
 surfaces--going back up to higher pressures if there are a lot of 
 rocks to preclude pinch flats.  All this with HD or ultra HD tubes.

Ross and Lou,
 My local welding shop had a killer deal on 'Cresant' brand tool kit 
 in a fold up kit--consisting of SAE and metric stuff.  I robbed all 
 the sockets, and small wrenches, ratchets, etc screwdrivers, etc and 
 built a 80% KLR tool kit.  I then went to harbor freight and bought 
 their 'black' metric wrench set for the axle wrenches--(Yeah, I know, 
 I could have (an do own) a Fredette wrench).  It is all in tool 
 sleeve with individual pockets for each wrench/tool.  It invetories 
 the tools when it is laying on the ground--something for every 
 pocket, etc.

Nothing much worse than trying to fix something with a 'sorry-tool'--
 it will leave you stranded.
