Just getting the bike here is the first step. If the quality is good, then I can build from there. Otherwise I'll have to start from scratch on something else (e.g. EX300R).
Yet to see a power part for the Duke 125/200 for an extended range tank.
The only way out is to go custom, would have been easier had it been a metal tank, but with a plastic tank not sure how go about increasing the range.
