Man that bike is way better looking and more complete then mine was when i first got it! im jealous lol. i would do a quick carb clean and run premix just in case that oil pump dont work. Carbs on these are real easy to work on.

+1 to Devin's reply.

Over here in the UK, and in the rest of Europe, they are referred to as trail bikes - indeed, some models have "Trail" instead of "Enduro" printed on the badges. They were rarely used in competition as far as I can remember, just for what we term "green laning" on non tarmacked roads.

Any one else have 2 throttle cables and where do they go . I’ve read one goes to the top of the carb and the second is for oil but can’t find a picture how to hook them up .

Check on any of the online parts manuals, but there is usually a plastic tube into which the single wire from the throttle grip and the two wires for the carb and oil pump connect. This is typical for all Yamahas with the oil pump and the twin cylinder bikes had three wires to connect up.

The splitter, so to speak, is generally under the fuel tank. The throttle line goes in from the front, and the oil and carb lines come out the rear/underside...

There is a seller selling LT2 motor parts on e-bay. Looks like he is parting it out. I don't know anything about the seller, but you may want to contact him about the kick start assembly.
