Ok, I know this is not M109 related, but I'm hoping to find someone thinking "dang, I used to have one of those bikes back in the day..."
I just bought a used 1978 Yamaha DT400 cheap. It's in really good shape, but need a couple of questions answered.
1. How do you open / remove the seat? Most of the old trail bikes I had years ago had some kind of release for the seat. I can't find anything to release this seat, and can't even figure out what bolts might be holding it down. I want to get the seat off as it appears the access to the air filter is under there and I really want to get that cleaned out.
2. Is there a way to ensure the oil pump for the 2 stroke oil is working correctly without just putting regular gas in the tank and hoping it mixes? If it is not working, what would the mix ratio be to premix?
Now I just need to find a source for some cheap tires for this machine. It has 3k original miles (speedo / odo still work) and I'm guessing these are the original tires and are severely weather cracked.
And for those that get offended at non-109 discussions, sorry, but nobody appears to be very active on any message boards I found for these old enduros.
