I don't see anything about this in my searches... do any Liberty 50 owners have hot (like... too hot to touch) engine/trans casings on the left side? I nearly burned my bare left leg this afternoon, getting off the bike. Granted, I generally ride in much cooler temperatures and with pants or winter gear (down to well below freezing even). But in 3 years and 4,900 miles since buying this scooter new, I never noticed this much heat on the non-exhaust side of the machine. Oil level was fine... maybe ever so slightly higher than the full line. It was 95 degrees F, and I was running it wide open for a couple of miles, after what was a normal errand-running 5-mile circuit around town on flat roads. Anyway, would appreciate input from Liberty 50 owners on what should be a "normal" temp. Cheers. Paul

CVTs get hot, no doubt about it, and there are fan blades on the variator to run air through the casing and out the vent hole on the rear bottom of the casing. Is your vent hole obstructed in any way? Can you feel some air being pushed out of the casing at idle?

FWIW the only time mine got unusually hot (on my S150) was when the belt was old. Once the CVT heated up something emitted a disconcerting "hot rubber" smell and the scooter wouldn't go above 35mph.

I think old belts sometimes slip in the CVT at high speed and make the case particularly hot. At 4900 miles maybe yours is due for a change.

Not sure if this helps, but My 2020 BV350 transmission housing gets too hot to touch after a long time riding in 95* Houston heat on piping hot cement roads packed with cars emitting hot fumes.

I appreciate the replies! I will drive the bike again when the rain stops, on a cooler day, and see if there is any difference in housing temperature. I did not smell and burning rubber the other day, when it was very hot to the touch. Thanks again.
