Hi it is that hard if the pump is still in place. I cleaned the tank out with petrol/ paraffin. Blew air through it just to make sure it free flowing. I then used clear oil line. If you can see the oil. You know what it’s doing. Let it run all the way down and out then attach to the pump. There’s a bleed screw on the side of the pump undo it until oil comes out. I used clear again from the pump to the carb tighten the bleed screw and hold the pump lever open by hand wile the bike is on tick over you’ll see the oil going up the clear oil line and into the carb. Then Don’t use premixed fuel anymore. Hope this helps. It’s simpler than it sounds. Cheers

@@davemonday5381 thanks for the reply, i had the pump rebuilt by an old school yamaha guy and haven't had time to put it back together... family life. I had the bike professionally inspected and it needs a ton of replacement parts including an engine rebuild due to beimg starved of oil at some time in it's life. Pretty depressing.

@@braxtonw1993 I have same bike with same issues my auto lube system was all messed up I just mix it now but make sure you pull off oil line that's on the side of the carb also you can get free service manual pdf for 77- 78 enduros at www.manualslib.com they have alot of free informative manuals about the bike

I’m glad you found the videos. You should absolutely give the restoration a try. I didn’t have a clue what I was doing when I started (still don’t really 😂) and I’ve really enjoyed it. I know there are a handful of Aussies on the yamaha-enduros.com forums that are pretty active.

I’m glad you’re enjoying the videos. Hopefully your friend got his oil light working. My progress wrenching on the hikes has been very slow lately, but I’ve been riding almost every day.

Thanks very much! Sounds like you’ve got a nice collection started. I wouldn’t mind getting a DT400 for myself if I ever finish the ‘77 250.

Thanks! I’m glad they’re helpful. I’m learning as I go. If you want to see anything specific just ask for it in the comments.

Austin Pollock I paid $1200 for the 1978 DT250. It has around 7k miles on it and is fully functional. I also have a 1977 DT250 that I paid $400 for, but it was missing the plastics and needed a little work.

From my experience it can be tough to find bikes with titles. My state won’t issue a title for vehicles over 30 years old, but they do allow registration with just a bill of sale on vintage vehicles. One of my bikes doesn’t have a title, but I was still able to get a tag. It definitely hurts the resale value of my bike, but I was happy to be able to get it registered and street legal.

Does your state have ORV tags? I am able to legally use mine on and off road all over an entire 3 county radius with my ORV tag.

Mine was already a little bent up so it wanted to come apart on its own. Look on the underside where the cable connects and there should be two R shaped clips. Slide this out and you should be able to wiggle the housing apart. There might be some adhesive so be patient and go slow. I have not yet taken apart the internals to look at the gears. I’ve just replace bulbs.
