Top Front Engine bolt size?

toolittletime said:

Anyone know what the diameter of the long, top, front, engine bolt is? The one that holds the top of the crash bars.
I need to purchase one a good bit longer, but the same diameter, so as to fabricate my sidecar mount.
Thanks......Tim

The OEM front top engine mount bolt is hex head M12 HT 8.8 1.25mm pitch and 282 mm long.

If you're getting a longer one, you could think about a 1.5 mm pitch... and a locknut.

M12 it is then, I stayed with the finer pitch to ensure correct torque could be maintained. My local bolt shop had it in stock and I remember it was pretty cheap.
