Same here. Foliage is just about done in NW Mass and leaf covered trails made for some surprises. I bought my '07 351 a couple months ago and enjoyed some short trail rides but it wasn't until yesterday spending the afternoon with a friend and his WR that I really bonded with the bike. I've owned an XT250 and and NX250 and compared to those, It really does pull nicely. I've got a 2 Brothers pipe on it which the PO installed along with the Big Bore kit and Mikuni pumper carb. It's a bit loud for my preference. Reading about options, it seems the FMF Q4 muffler is a good option for a quieter aftermarket muffler. I understand the power trade off for a more restricted exhaust and am fine with it. I did post a "for trade" in the Flea Market in case anyone wants my 2 Brothers and more bark. I'd pay shipping for yours... FWIW, I'm getting right around 50 mpg's with mine as well.
