OK - truth be told I am not a master mechanic (yet). I plan on learning along the way but have this fear of screwing stuff up on my new bike. Soooooo, I hope you dont mind some elementary questions on the free mods... Can anyone point me to an old thread (or other) with pics of the exhaust mod? I want to be sure I take out the right thing and leave the rest! Also - I have my yz throttle stop on order (should be here next week). Do I need to pull a lot of stuff out to get at it or can you remove the housing without taking apart a bunch of other stuff? And finally, after reading the manual it looks like you have to take the carb off in order to change the jets. How long and how complex a procedure is this for a rookie (again, I'm not a complete wrenching idiot but don't have experience working on bikes yet) thanks in advance for any help!
