Stage II is Stage I, dyno tuning with Diag4bike in combination with a camshaft and pushrods. The M8 models benefit greatly from a camshaft because they come standard from the factory with an even negative overlap.
Depending on your driving style, you can choose a camshaft with a lot of power at the bottom, or a camshaft with more top power and less power at the bottom (torque).
You can choose chain or sprocket drive.
You get a stick, an adjustment on the dyno, an S&S camshaft with Timken stronger bearing and a set of adjustable pushrods, with black or chrome sleeves.
The costs are 1900 euros including the Diag4bike stick.
(including assembly and adjustment and dyno proof)
A special Star Racing camshaft is also possible for an additional 400 euros.
Various additional changes are possible, S&S Cuffs, other Tappets, etc. are always possible in consultation.
Of course it is also possible with a Thundermax computer instead of Diag4bike, for 800 euros more.
