I have had the tank off my bike for 6+months I recently (last weekend) had finished with some repairs and tried to re install the tank. It would not go. I could get everything hooked up to the fuel pump but I was unable to push the rear of the tank down far enough to install the 4 bolts that hold the bracket in. My tank is plastic or nylon whatever the 03 mille has that wasn't metal. SO what I did was remove the lower subframe bolts and pivoted the subframe up to where with the 2 front bolts of tank installed i could then install the 4 on the bracket. Then I pushed the subframe back down to screw in the bottom bolts. I plan on leaving it like this for a couple of more days. What I am hoping (and kinda asking is) that the tank will stretch (for lack of a better word) or reshape itself to fit properly or do I just need a new tank.
