As many of you know, no one makes a larger gas tank for the XT225. I've found that at 60mph i'm only getting aroudn 60mpg giving me a fuel range of 120 miles. For my trip from VA to MO this winter, that's just downright pathetic, so I took matters into my own hands to make a larger fuel tank. (technically the boyfriend did all the welding; i couldnt MIG my way out of a paper bag!) Stock fuel tank volume is around 2.4 gallons. I'm aiming for something around 4, preferably 5. That would give me around 250 miles before I sputtered and died on the side of the road. Much preferable to 120... I had considered making a tank from fiberglass, since I have the most experience in carbon fiber and they're sorta similar... but the boyfriend wanted to practice welding and thought it'd be easier, so we went for it. the bike itself is a 2006 XT225. Already has some trick shit on it. build thread here: http://www.advrider.com/forums/showthread.php?t=396200 Started with a rusty stock silver tank off ebay Marked out the cut locations and ground the paint off We left the rear triangle area attached to make a smooth curve where my knees would go. we then cut the rest with a dremel type widget and pried it out. keep prying until it was sufficient huge without being just retardedly huge. :eek1 it is a pretty small bike, you know. now on to both sides! Thats looking better isn't it? the only other larger tank i'd seen for an XT was one some japanese guy made forever ago but pretty much raising the filler upwards. So we went ahead and added that in as well, seemed to help with volume a ton. I have aftermarket handlebars and risers so that allowed me to expand it a lot more than I could have with the stock bars. Something to think about if you try this at home later.... It's starting to show the final shape now kinda. Check out the thread up top for stock pictures to compare. The stock tank is tiny tiny... This is starting to feel more like the 6.6gal acerbis I had on my KTM.
