Rotax RM 1 Benutzerhandbuch Seite 122

The "curve of driving resistance" indicates the driving resistance of the vehicle. Depending on the
weight of the driver, the gear reduction ratio and the grip of the tires this curve may move
downwards or upwards.
The "performance curve 1" indicates the curve of engine performance of type 125 MAX DD2 at
optimized adjustment of the carburetor main jet. The curve of engine performance is up to the
maximum r.p.m. always above the curve of the driving resistance of the vehicle. The engine
theoretically can reach the maximum of 13.600 r.p.m.
The „performance curve 2" indicates the curve of engine performance at
ajdustment of the carburetor main jet. The curve of engine performance crosses the curve of
driving resistance of the vehicle sooner than with optimum jetting. The max. r.p.m. in this case is at
the intersection of the two curves (in this case at approx. 12.800 r.p.m.).
For better understanding and as help for carburetor adjustment the following sketch describes the
effect of the various adjustments, depending on the actual throttle position.
