tappet adjustment 860/900 gts

Post by macduc »

manual says inlet 0.08mm (003 inch) and exhaust 0.12mm (004inch). some say set a little larger i.e. inlet .1mm (004) and exhaust .15mm (006) any thoughts thank you?
What are the standard tyre sizes for standard boroni spoked rims front and rear for 1979 GTS 900? Also what are correct pressures front and rear? tar!!

Just noticed this......

My factory workshop manual for the 860GT/GTS specifies 0.08 mm intake, 0.12 mm exhaust. The only conflicting recommendation I have ever seen is to reduce the gap somewhat.

Tire pressures give a range from 31.3-32.7 psi for the front, 35.6-38.4 psi for the rear. Tires are 3.50H18 front and 4.00H18 (USA) or 120/90H18 (standard) rear. As far as I know, Borranis were never fitted to GT/GTS models.
