Been away too long! Life and work took me away from riding for a while but I recently picked up an '07 DRZ400SM (11,000mi) found here in Hawaii for $2500... Seems like a pretty good deal and the bike's in good shape. I'm going over it and taking care of the "must do's"...thanks to all for contributing all the accumulated knowledge! I'm swapping the stock gearing to a 14/44 setup(the 15/41 felt like it had no first gear!), not much need for speed on this little island that I live on... hoping that's enough (no real serious hill climbing in my future and at 45 years old my motocross days are behind me). I've got the JD kit on its way with the 3x3 mod planned. I kinda like the 17" wheels with the fat tires and hoping that they will be okay for the trail riding I will be doing... a little worried about the rims being so wide and seemingly vulnerable. The bike currently has IRC/Kenda GP1 enduro tires front and rear (4.6 front and 5.1 rear), they are a bit worn and so far seem okay except in the slippery clay/mud we have here... in the dry and sandy conditions I was happy. I want to keep dirt tires on it as most of the riding will be offroad. Any advice?
