Vacuum nipple adapters – carb sync

Wanted to reply in the original thread but it was locked - http://www.thegsresources.com/_forum...654#post838654
The poster was complaining about paying $7/each ($21 total) for 4 brass nipples. I too thought that was a lot.

These can be had for less that $1 each, shipped from eBay (as of 5/2013)

5mm vacuum adapters are used for R/C boat cooling nipples. Search eBay for “5mm nipples boat”

Here is a link for the ones I ordered 5 for $4 shipped (who knows how long this link will last) - http://www.ebay.com/itm/M5-threaded-...item1e5adc0316

Good find, however they are really short. Might be a little tricky to work with but big savings.

Nice- you can always solder on longer tubes.

[Crazy_Russian]

they look about the same length as the short ones from z1, the z1 ones work fine.

Ordered a set- 4 $ can't go wrong. We'll see what they need.

First of all, your math is funny (4 x $7 = $28).

Next, for some reason, I can't seem to connect to your link, so had to do the search.
Those things are AWFULLY short and you will have LOTS of fun reaching the inner cylinders.
Sure, you can solder on some extensions, after you buy the tubing and spend the time to do the soldering.

Just so you know, the adapters from Z1 are $8.27 for the set of four.

I bought a set of 4 for Yahama cycles ( 6MM threads ) for 12 bucks and change from Ebay..and that included shipping. They are Motion Pro carb adapters.

Ed, do you have a picture of the one's you made?

[chuck hahn]

You can also but threaded brass rod and drill a hole down the center..its very soft and ease to drill. Then just smooth off the threads where the hoses attach and your good to go.

Yes , you cant make 6 inch long ones for the two inboard ports, but you really only need about 1 1/2 inches sticking out anyway to attatch the hoses. Just be carefull when taking them off of a heated up engine so as not to burn yourself.

Chuck, I bought plain brass rod, drilled and threaded it. Then it was a simple matter to thread a nut on and slip an o-ring after the nut was in place.

[chuck hahn]

Yup...thats basically what some of the 6mm ones on ebay look like. You gotta buy the die, but the die can be of future value fixing a thread on a bolt or whatever..so its not a "one use" investment thing.

8 and change plus shipping- take about 5 minutes to solder on extensions and I have brass tubing- could even use copper- but each his own- I think the ones in the set are actually a little to short for my hot dog fingers.

You can solder the ends of the extension tubing shut and drill a .030 size hole thru the plug to further add to the ease of dampening the guages when connected to the bike.

If you look at the ends of the Motion pro, or other brands, youll see they have just that tiny hole at the end.

EDIT...I am guessing on the hole size..but its pretty small. Maybe .015 or .020 would be closer??
