Offhand, I dont know of any place where there's a published list persay...just several other posts like this with folks asking about what mods they can do to their bikes...
Here's a partial list:
- Cut down the stock throttle stop (stock length only gives you about 1/2 throttle capability!).
- Remove the airbox cover (allows carb to breathe better...more power).
- Re-route the various carb vent lines into the airbox (helps keep water out of carb when bike is running and stuck in a stream).
- Cut the grey wire (you'll have to read-up on this one...didnt notice any improvement myself).
- Adjust the front and rear suspension to your riding style and weight.
- Change to YZ timing (helps power in mid to high end, sacrifices some of your low end...personal preference).
- Uncork the exhaust (if you're riding in a location that this is appropriate).
- "BK" mod (limits the amount of fuel being poured into the carb by the accelerator pump when opening the throttle...removes the low-end "bog" you most assuredly will have).
Now, some not-quite-free but definitely worth while improvements:
- Jet the bike correctly (2nd biggest performance improvement over shortening the throttle stop).
- PowerNow/JamesNow mod (helps with airflow into the carb from 0 to 1/2 throttle...good feedback on this one, but havent done it myself yet).
- Get rid of the stock tires and purchase some Michellin M-12's or Dunlop 756's.
That should get you thinking and keep you busy for a while. I suggest doing searches on each of the topics listed above that you're interested in. There's a wealth of information out here on this site. Also, dont be afraid to ask questions!

$160 for YZ cams? Geez...I wouldnt be doing that mod either. Money's better spent on new tires, jets, hospital bills, and post-ride cocktails!
Anyhoo, check these mods out Bibmen and ask when you have a question. Again, from my viewpoint, throttle stop #1, re-jet the bike with YZ jets (or JD kit jets) #2, then the others as you see fit. Makes a WHALE of a difference...trust me. Different bike alltogether.

One of your posts awhile back, you had ordered the JD kit. Have you tested it? If so how did it go. Are you getting to ride much in MN?

How's your bike performing at that lower altitude? Notice the increase in power with a little more oxygen huh. Good to see your post.
Yep, 81 today, 80 on Friday. We're getting a cold front moving through on Saturday. Will lower the temps to the 60's but will be back up into the 70's on Sunday. Late fall this year, Aspens are just now dropping their leaves.

Yeah, the bike's running VERY well with the jetting I've got now...and yes, more oxygen certainly helps! Got that JD kit...but havent put it in yet. Next weekend will only be the 4th ride of the season for me! Geez... Been working out of town during the week in CA, so time on the weekends has been scarce. Once I get a chance to try it out, I'll let ya all know how it compares with what I've got now.
On the positive side of things, we're renting a house right on the Mississippi River...so many a smallmouth bass has found their way onto the end of my fly line! And then there's CKULZER coaxing me to get studded tires so I can go ice riding once the lakes freeze...that should be interesting!
Anyhoo, things are going well...just not nearly as much time on the bike as I would like...but that'll change here soon I hope. Keep on riding Rampart/Georgetown/etc. before the weather gets bad and/or the next disgruntled forest service person burns it down!
