Inlet and exhaust valve sizes

[fritzwilliger_imp]

Does anyone know the inlet and exhaust valves sizes.

Here's what I found:
Inlet valve diameter is 27mm, with a 2.5mm stem;
Exhaust valve diameter is 24mm, with a 2.5mm stem.

I assume that these specs apply to US bikes which have the same 1140 cc inline-4 motor, which is manufactured in Japan.

Hope this helps!
