Fred,
You might be confusing the two daves. Dave Martin had a qt-50 that was "pimped out" and got stolen....he had an extra gas tank on there.
The other guy, Just "Dave" didn't say what ped he was riding.
and as an owner of two 1982 QT-50's, mine don't have pedals, so there would be no clutch lever. And, I'm getting awful mileage on mine-- but it is running great. I think the tiny "underseat" gas tank is a bit small. 1/2 gallon or less...
I'm not sure if they ever made any QT's with pedals... they could have....
My reserve tank is not functioning---needs a new petcock, probably. makes it even worse when I run out of gas.
