Technical Help



Advance curves, that is certain characteristics of change in ignition timing relative to engine speed, are a must in 4 strokes and might be interesting in 2-strokes used for amateur racing purposes. On 2 strokes however often the expense will not be in relation to the effect and at any rate advance curves are no wonder cure for old engines and do not tickle more HP out of them.

Our offered systems (4strokes) contain an advance characteristic that is the result of our prooven experience. All those curves have been made for unmodified, standard engines and are not aimed at tuning.

Though our advance units have (for reasons of economy) more than one curve inside, only the curve(s) described in the installation notes have been tested for the material refered to. We know that the curves cited work with the engines in question. We can not give any other, supplementary recommendations.
