where is the picture exactly ?

[Yamammar]

have a Ct-175 picked up recently - bone stock - but leaks like hell out of the Oil pump - i mean puddles on the floor.

i'm thinking of just disabling the pump anyway and going to premix oil in gas. For some reason i don't have much trust in the Oil pump - have heard on long downhills off throttle engines overheating/whatever and siezing up .

Any comments ? advice appreciated. 1,400 miles on Odo.

John before you disable pump. Remove hose and wash... take a good look I am almost sure either feeder tube from tank or hose from pump to Carb are cracked! Yamaha built an extremely well designed pump.

Anyway if you clean mess up and replace both hoses (cheap!!) then prime pump and wipe dry and let sit over night. Put some cardboard under as it will really show leak fast.Then you can use a weighted string to line up where it is exactly coming from.
