Good afternoon Referring to Step 10:
My tank doesn’t look like this. It’d only got 2 nipples where the fuel hoses connects to. Can you please clarify this for me? PS: you refer to the fuel pump as the “rear pump or pump at the rear”. Does this mean that there is (or should be) a fuel pump in the front aswell?
Hey. If you have a tank thats only got 2 holes under it. You have a classic Comet tank which doesnt use a vacuum tap.
So each hole under tank (2 of them close to each other)
Goes down to the MANUAL ON/OFF TAP that is mounted on the left side of the bike frame. Usually older comets with Silver Frames have this.
Late models switched to vacuum taps (hence needing a vacuum pipe from intake manifolds to make turn on/off automatically.) (& all GTR 125 whatever year they always are vacuum type taps)
REAR PUMP = It sits behind the rear engine of your bike.
As you saw in the pictures above ^. There is only 1 for all GT / GTR from 125cc to 650cc carby bikes. Its the same Mikuni unit Koreans use. Carb is a Mikuni too 😉
