Sweet, welcome to the club

For all your thumper needs, check out
www.thumpertalk.com which has a very active DRZ section with quite a few experts that know their bikes. They also have an online store that price matches.
I got my 450cc big bore done through MT Technologies
www.mt-llc.com or you can go through Lukes Racing. Just send in your cylinder and in like 2 weeks you'll have everything you need to put it back together.
The first mod you should do is to rip that snorkel out of your airbox and cut a hole 3" x 3" to let that thing breathe. If you're going to stick with the stock carburetor, get a DynoJet jet kit from thumperstore. This jet kit when coupled with the 3x3 mod shows an increase of power everywhere with an incredible 10whp gain up top. Throw a full exhaust on there to really uncork it.
The best mod you can do is swap out the CV carb with a 39mm FCR pumper. It ain't cheap, but it's worth every cent.
The next best mod is to swap out those mild cams with a set of Hotcams. I got the intake and exhaust cams for about $290. I think they sell them at thumperstore now.
Warning on doing the mods: it's extremely addictive! The stock DRZ S puts out about 35whp and mine put out 47whp with low compression gaskets and no fine tuning on the carb. The next mod for me is a 5mm increase in stroke which will give me 480cc and with high compression gaskets, I'm hoping for about 54whp or so.
You're going to love this bike.
