Takeing carbs off Friday...What are the different size Vac. hoses that I will need, I can see alot of them from top and know there are more under carb...Thanks in Advance for any Pictures or Advice.

Most of them are the small size. Pull one of them (or a connector) off and get it matched at the parts store.

Hey Bobboo,

If I recall correctly, I used 3 sizes in mine when I rebuilt my bike last winter. I did not have to use any Honda hoses, not even any of the preformed ones. I replaced them all. I think it ended up being 3 sizes in total… I purchased two sizes in bulk – 10 feet each and then a 2 foot for something else.

I’ll dig out in the garage tonight to see what I used. You will see a bunch of carb pictures if you click my name and search through my past posts.

Tim.

I recall only using one size of vacuum line... that might not be correct, but it's worked. I merely bought about 30ft of bulk line, and replaced everything, even the pre-formed lines.

These are metric hoses, so get metric if you can. You will have to go to a shop that has supplies for foreign cars. If you go with american hose, it will be to small and over time crack at the buldge.

Just FYI if you have a service manual there are some very good illustrations on the locations of all the vacuum lines and vent lines in the "Fuel" section of the manual.

Bobbo,

I am so sorry I totally forgot to look for the NAPA receipts for the VAC line to find their sizes. I just dug them out but the descriptions don’t mention the sizes. So I measured them…

3.2 mm, 4.2 mm and 5.8 mm. Keep in mind it’s hard to measure the I.D. of a rubber hose.

Again… Sorry about that.

Tim.

...3.2 mm, 4.2 mm and 5.8 mm...

how do you make those 90 degree vacuum line out of those? what's the trick?

Xamper,

The following pictures should explain themselves.

Make sure the spring you insert in the 180 degree bend is tight. Work it in with silicon lube.
