Last fall my boss bought a new gas tank for the motorcycle. Yes, sometimes I use the motorcycle for work. I opted for the 5.8 gallon version. The stock tank is 2.something gallons, which with the 650 gets me somewhere around 100 easy on the throttle miles. As you can see above, the new tank is more massive than the old tank, it does however weigh less and when you consider the little wing-a-lings attached to enhance cooling with the old tank vs including wing-a-lings into the new tank, it isn't that much more bigger.
This is what the bike looks like without the seat, some plastic and the tank. I didn't take a pic of the bike before stripping it down. The current tires are Kenda K270 on the rear and Dunlop something or others on the front. The bike has 3400 miles, the rear tire is just over 1000 miles and the front is new with around 50 miles. I ride the bike mostly on dirt roads with some trail riding and some highway. I think that the current tires wear fairly well and while the tires may not be the best for the trail, my riding skills are as much a prohibitive factor as the equipment.
I think it looks good. If it were my bike, in addition to changing the gas tank, I would remove the smog equipment, speedometer, tail light, turn signals, head light, the stock handlebar, the stock muffler and the skimpy rock protection. I would add a LED headlight, LED taillight, LED turn signals, skid plate, aftermarket trail computer, XR 400 oil cooler, big bore kit-10:1 compression, change the camshaft, de-restrict the carburetor, and put stiffer springs in the suspension to support my 250lbs. The mods I want would shave off 30lbs and add around 15 horsepower. Currently the bike makes around 30hp and weighs 350lbs. Now to convince myself that I want to spend money on a bike.
