Adjusting valves is more like checking valves. You'll need feeler gauge, available at Auto-zone. Needs to be the flat type, not the wire type used on spark plugs. Follow the instructions on the tech tips to get "top Dead Center".
If you are not mechcanical inclined, then I suggest you go to
http://www.suzuki.com and do the dealer locator link. I just did and there 20 dealers within 150 miles of Pittsburgh. Maybe I should have done 100 miles. Don't want to have to get gas 2/3 of the way there.....
I'm from eastren PA and found that it's much nicer to have the inspection due in Fall. It's a ten minute wait then. My friends comes due in spring and he waits two to three weeks to get in and has to leave the bike overnight.
Those of you not in the state of PA, we need to get the bike looked at, once a year, to have a licensed mechanic say "yep, it stops", "Yep, the lights work", and "Yep, the tires have tread". The date your inspection is due is linked to the date your vehicle liscense plates come due (double zapper, got to love the gov't).
