[jfman]

Hey guyz

I work a lot on old bikes/carbureted bikes and I am ordering a roll of quality fuel line direct from Honda.

I can choose between 4.5mm ID or 5.5mm ID. Which size should I got for?

My bikes and the bikes I may work on are the following:

1974 Suzuki GT500, 1980 Suzuki GS400, 2003 KLR650, 1983 XR600, Triumph 1967, 1981 Suzuki GS850, Kawasaki KLR650, Suzuki DRZ400
