I would appreciate some input into what gas tank I should go with for my 07 DRZ400SM. A few things first though. I would like a range of 200km(160ml) or better without a huge jump in discomfort if at all. Painting suggestions.( For best quality, all the aftermarket are plastic ) Quality-fit and finish I plan on an aftermarket seat so fit is important. With that said I also have some engine mods-gasket, cams, carb, 3x3 and full exaust. With these mods and the stock tank I get about 130km before reserve. So all in all about 140km before I'm done. between 30-35miles to the gallon or 60-70km gallon. I'm also thinking of going to big bore kit( 440 athena most likely ) in the future. So I would like to compensate for this possibility. I've thought of changing the gearing, but only if and when I go to the big bore. Thanks for the input. I know it's a lot to consider but thanks the same.
