If you mean the 12mm black hose running down the frame on the left side, yes. It has absolutely nothing to do with the hot start, though. Don't know who fed you that one.

The hose is the crankcase vent. Your piston moves 450cc of air out of its way as it runs down the bore, and that pressure needs to go some place. Normally, you'll see air pulsing in and out at an idle, and maybe a bit of oil dripping if you run it hard for a while.
