Bike guys, help.

Couple of places online have the petcocks for your bike. Looks like $25 bucks gets it done.

Thanks! I see they even sell replacement turn signals. Someone busted off my original rear turn signals (the spring loaded ones that fold over) My bike currently has "fixed" / solid signals from a honda because of that.

And worth every penny.
Those are good bikes and I'll bet that one scoots.
I used to have a DT360 when I was young and stupid. (never hurt myself on it though) :-)
I have an XR500 Honda now. (old and stupid?)

Oh it really scoots, I installed the "hotter" top end from an MX175 instead of a DT175. The MX was the off-road only version, more aggressive than the DT (Street-Trail) version. On such a light bike, it made for an awesome upgrade. And since I only weight about 116 pounds, the bike doesn't even know I'm there.
