Motorcycle race mechanic. Having retired from stock car racing ( F2 B,R.I.S.C.) I now look after my son, almost every Sunday motor cycle racing. Enduro in the winter & motocross in the summer. Enduro is a 3 hour race over rough ground with laps of up to 8 miles. So they have to pit at leased ones for fuel, fresh gloves, goggles & energy drink. That is where I do the most with a F1 pit stop, (I wish). Motocross I mostly just get to watch. But some times I have to drive the van home, 3 times to the hospital. Two rocking bikes I made for the grandsons. last me when I was young , well 50s young when your 75.
