Re: Hammer of the Gods - B50SS Project

You need the lobe on the cam facing the gearchange quadrant, the slot will be upright. Dab a bit of paint on the top of the adjuster screw to show you its in the correct position and not 180 degrees out,adjustment should then be no more than 90 degrees either way from the vertical position.

Re: Prop stand

The oif 250, and early b50ss/t machines had a hook type spring anchor on the prop stand, this changed to the barrel type on the later ones, both had the cross hatch on the foot.

Re: cam followers

The later thick foot followers were fitted as std on the oif 250 singles. But I have found on a few of the very early examples the earlier thin foot type had been fitted from the factory. The b50 always used the thick foot type (71-2513) from the start.

Re: Shifting into third issues

Its also possible if 4th gear cant be selected, that someone has not positioned the detent spring correctly causing the mainshaft selector to foul the spring hence stopping it from passing.
