Fuel line routing and fuel delivery.

Hello Scotch, I have merely brazed on a "T" to each of the drain bolts, purely for ease of removal to drain the carb bowls when leaving the bike sitting for extended periods of time. They seal quite fine with the "O" ring and finger tight.

where can i find pics of the proper fuel line route?

I have at last solved all the problems I had with fuel delivery. I fitted a Pingel fuel tap and turned it so the outlet faces towards the back of the bike, I also turned the fuel inlet "T" upwards so the fuel line connects from above. This set up gives me a fuel line not much more than 6 inches long, and it tucks up neatly under the bottom rim of the tank. I thrashed it up the motorway today, all the way from the Forth road bridge to Perth and back again with no sign of the power dropping off. At the moment I am relying only on the gauze filter on the Pingel fuel tap, and I have not fitted an in line filter. That said my tank is almost like new inside with no signs of rust or debris, I think it was treated with some kind of sealant when it was new.

I agree, the fuel line should be routed above the carbs and the electric fuel valve removed.

I have a similar arrangement, with a fuel filter.
