It is a bargain priced, simple air-cooled do everything bike. Off road the handling and suspension were better than expected, but the ride is not plush off road. It gets great mpg, mostly very reliable and durable. Some fixes: The gearing is way tall-tried various sets: the 44 rear tooth is the way to go (42 stock). Street/freeway is still good, and off road much better. The bonus is it pulls the rear wheel forward putting more weight towards the rear for less knifing and better wheelieing. Drill the muffler plates thru all 4 with a 1/2" bit. Adjust pilot jet 1/2 turn out additional from stock setting. Raise needle with small washer. This will increase your low end torque which the DR is weak on. It improves top end power a little. And it still won't be loud at all, just a little louder with the same sound quality. Change the main jet to a 145 (mikuni large round) only if you modify the air box. There have been various mods on the net for this bike's air box-you can screw it up and make the bike feel lazy! If done right you will have much more tractability at low and med. revs and more power everywhere. I recommend do not remove the snorkel! Do drill two 1" holes on the top of the air box close to the front of the bike-there is space there, behind that put a row evenly spaced behind those of 1/2" holes three each; followed by four 1/4" holes. Round holes flow smoothly, the setup allows good flow without ruining air box pressure-no pressure from vacuum=poor incremental response! The sizing of the holes permits velocity of air increase to match low to mid to high rpms. Last if you insist on a slip-on, I recommend Supertrapp or FMF; this will probably require an additional 1/4 turn of the pilot, and may take a 150 main jet. DO NOT WASTE MONEY ON A JET KIT!!
