Carb hose replacement

Postby GillesGLW » Thu Mar 10, 2016 5:29 am



Greetings from Switzerland,

I'm currently rebuilding my carbs on the 1500 and I bought an overhaul kit. However I noticed that some of the hoses around the carb were damaged.

I'm looking to replace them and I have the following options:
- buy new ones from Honda, separately
- buy some carb hose and cut it myself at the correct size
- find a kit of hoses, ready to be installed

What would you recommend? My Honda dealer told me (obviously), not to go for standard carb hoses as it would bend with the heat of the engine, while Honda's hoses are already bent and ready to be installed.

What have you done on your side? It seems complicated to buy hoses one by one from an Honda OEM dealer (like Cyclemax for example).
Is there a kit available?

Thanks,
Gilles

Giles. I don't remember the sizes or how much was needed but there is no reason not to use automotive vacuum hose. There are a couple with 90º bends. I cut those hoses a littler longer than stock to prevent too sharp of an elbow. No problems.

+1 on regular vacuum hoses..some put in a barbed rigid elbows for those 90* bends..that is the weak point in the system, those 90* bends. That adds another possible leak point but with new hoses and quality elbows shouldn't be an issue.

Thanks to both of you for your reply!

Do you recommend any brand/model? I went on Amazon and there are 1000 of hoses... sillicon, heat resistant, blue, green, yellow, etc.... :D

heat resistant is a plus it is a hot spot and there is a heat pad under the carbs to protect everything somewhat..but it's still hot...color coding good too if you look at a parts spec in the manual the OEM tubes are color coded..not needed but nice..of course once you change all the tubes you shouldn't be in there again for 10 years or so at least???

the more I look for them, the less I find them!

Did you buy yours from Amazon?

2 cents from a guy who hasn't done this project yet. I'd use regular vac hose for the majority of the lines that don't require sharp bends, and then buy whatever preformed lines are needed from Honda, Cyclemax, etc. Should keep the cost down, and provide less headaches for any hoses you may have missed (since you'll probably have some left over).

I started looking for these hoses awhile back. Didn't give up but its difficult. They are all metric and nobody sells metric hose here in the states. Although you can buy in bulk from Honda. But its a shame unless your doing more than 1 bike. The hose isn't cheap and you have to buy so much of it. I can't recall the sizes either but I think there are possibly 3 different sizes.
