Hey there,
I've got a '68 175DT that's recently made it out on the road for the first time in decades (it had been someones parts bike). Runs pretty good at higher rpms and goes up to about 60MPH, but a little sloggy in the lower/acceleration.
Anyway, after a 25 min ride, BOTH headers measured up to 250 degrees F. Now I don't know what they should be, but I'm assuming that's considered very hot as the exhaust connectors burned up. Why question is, what could cause this amount of overheating? Is it possible for mixture, or clutch to do this, or are we talking something more?
Next question, I don't think related, although I had that it was until I realized both sides were heating up:
It's leaking gearbox oil from the drain hole behind the left cover. For people who know these things inside and out: Is there something other than a case half leak that this could be?
Thanks for listening!!
