Advice on 1988 DT50

Hello all,

First Yamaha for this guy. Bought neighbors DT50 for my young one to learn how to ride/shift.

Kicks over and starts/runs fine.

Instantly goes to full throttle.

Also, tach doesn't work and has a a couple broken lenses/stalks for signals.

Are these easy to still purchase? Are any of these easy fixes?

It is still using the Autolube system, which is working. Should I keep using it or bypass for premix.

All of my other smokers are vintage and use oil injection, but are all Suzuki. Is the Yamaha system as reliable?

Other than that, the bike is in solid original condition with only 1411 US miles on it.

What else can anyone share on the older DT bikes? Has a DG pipe replacing the stick pipe. Not sure if carb mods were done, but looks like this pipe has been ridden on for a while, so not too worried about running lean.

Thanks all,

Jarrod
