Just finished mapping a slightly tuned DS1000 and thought I share the result.
The engine is bored to 1123cc, DP cams, one mm bigger inlets, hc pistons, stock diameter 2-1 and the heads taken care of by Erik Larsson in sweden.
It now lives in a sportclassic so a comparison with a hypermotard with the same DP cams and 2-1 will shed some light I beleive, they are similar in size, have similar airbox and similar exhaust. The hymo is also fully mapped out.
