Mugello gearing with Franspeed supertourer

[shuba]

Hi, i changed from a jl4 to a franspeed supertrourer. The Stourer is impressive, but only made 105 kmh on the Gps. The complete setup is Li150 s3 spanish, mugello 186, Phbh30 with 115 main. Currently using the standard clutch crown and 16 tooth in the front. Was dynoed on summer about 18bhp (so optimistic machine imhb) with the jl4, but poor on the hills.... Now pulls and pulls but, not really fast. Any gearing recomendation or similar setup anybody?
Thanks

Spanish li150 series 3 gearbox?????? If so there's your problem. Too big a jump third to fourth

That's the 1st thing I thought. You need the Italian LI150 box mate.
