tzed9 Posted April 17, 2018 Share Posted April 17, 2018 Hi all On replacing my engine (VTECA9) I struggled to verify in the pdf manual the routes for the breather and overflow hoses Called A2 on the A2 for advice and we agreed they should both go to ground along with the coolant overflow 4500 miles later it has started to misbehave and second on the list of troubleshooting checks is 'Fuel contaminated/deteriorated', which got me to think about the routing of these hoses again Would anyone be able to comment on where these hoses terminate if not ground please Link to comment Share on other sites More sharing options...
tzed9 Posted April 17, 2018 Author Share Posted April 17, 2018 Also forgot to mention Friend looked at another example bike at the office it had only two hoses going to ground hence my concern Link to comment Share on other sites More sharing options...
Member Contributer Terry Posted April 17, 2018 Member Contributer Share Posted April 17, 2018 I presume you are talking about the two hoses connected to the tank underside. The larger one is for overflow while filling the tank, that definitely needs to terminate under the bike so spills are directed to the ground not the hot headers for example. The smaller one is specifically a breather for the top inside of the tank, and that also should terminate under the bike. The 6G manual that I have shows the following diagram.

Member Contributer Terry Posted April 18, 2018 Member Contributer Share Posted April 18, 2018 Hose routing is right near the front, general info section I think. Link to comment Share on other sites More sharing options...
