My 1100 evo Hypermotard manual state same belt tension front & rear. I know some dealers/service outfits set front rear differently on air cooled motors. Any thoughts recommendations? cheers chris
Wisdom dictates that the horizontal/front cylinder is exposed to more air and therefore runs cooler than the vertical/rear cylinder which will expand more and have a tightening effect on the belt. I have seen people use 10mm of deflection on the front and 12mm on the rear to take this into account, usually in the form of running a 5mm allen key through the fixed roller on the front and a 6mm on the rear. YMMV.
Some info here, but I wonder what the temp difference is and how much actual science the recommendation is based. Ducati Suite- Belt Tension Adjustment
No belt manufacturer recommends this as far as I know or even Ducati for that matter. I used to do it on my SS when using the allen key method but I haven't herd of any differential frequencies if you are doing it by Herz...
