I have a drz400, they're good bikes. I would respectfully disagree with you about the fcr pumper carb. If you can find a good deal on one, it will add a lot of fun to the drz, while still maintaining it's legendary reliability.. Will it perform like a modern 450 mx bike? Of course not. But it will greatly improve the throttle response and widen the torque curve of the engine. The bike will pull much harder and have more top end power, which is very good for highway use. I feel like many people that say you shouldn't bother upgrading the drz400, are being snobs, and/or are also missing the point. Some people just want better throttle response, and for that reason alone, it proves to be worth doing for them. These bikes come very choked up from the factory, and even adding an exhaust, jet kit and opening up the airbox some, makes a substantial performance difference.
Motorcycles are a little bit like golf clubs, in that no one single bike can meet all of your potential needs. I have put about 2000 miles on my DRZ and I do enjoy that it is quiet, smooth and gets good mileage. So for cruising to the store or down some smooth flat dirt roads it works very well. I also have a Yamaha WR 450 that I have street legalized and it blows away the DRZ at everything, except being smooth and quiet. No matter how much you spend on the DRZ it will not out perform a street legalized WR 450 at aggressive off road riding. If the DRZ was my only bike, then it would be worth following your suggestions to get more performance out of it. Thanks for the feedback.
