My V1 engine head is extremely hot to the touch after maybe 15 minutes of riding.
i'm running a 68 jet on a dellorto 14.12 (no airbox) with an 11 tooth gear and a bullet exhuast. Plug chop produced a nice darkish brown.
Could low trans fluid cause this because i have a leak in the case (fluid seems to drip from where the pedals poke out of the case).
