Hello Technoholics,

I have a power lack again. Pretty sure it's in the vacuum lines/airfilter somewhere. Not the first time so I want to replace all my vacuum tubes/hoses and want to buy the tube by the meter instead of the Honda precut ones (much cheaper/more flexibility). Now these tubes come in several diameters. Does anyone happen to know the inside (metric) diameter of these tubes? Hate to order when working the bike. Just the vacuum/air tubes, NOT the fuel tubes.

TIA,

The vacuum line size for the intakes are 3.5 mm.

A desmog would eliminate alot of sources for leakage.

The fuel line size is 8 mm.

Good Luck   cooldude

Honda sells a bulk roll of the tubing. You don't have to buy it precut. It's about 26 FT (1000CM) for $45 shipped. Honda Direct Line has it listed.
