Homemade Manometer

[Stoyle]

So, I've decided to make a home made manometer, but I'm having a hard time finding specifics on connecting the tubing to the carbs, what kind of attachments do I need? Please help me! Bike is a 77 CB750 Four.

Eek I think they are 5mm brass nozzles that screw in and use a rubber oring to seal.

EBAY is your friend for stuff like this.
Actually, if you want to be sure, go to your local hardware store, buy a 5mm and 6mm screw, and see which one fits best.  Start with the 5mm.  Re-Run is most likely correct.

Hope it helps.

You may want to check on it but when I rebuilt my carbs I used a 10-32 x 1/4 stainless socket head for the plug off. It went right in with no problems.

I have made one of these things myself I went to Lowe's bought some 1/4" clear tubing  I had to go to the local hydraulic store and get some fittings they were 10/32 x 1/4 quick connect fitting which were about $3 each you need 4 then you need 2  t's to connect all the lines use motor oil or fork oil for the liquid I tried red coolant it was to thin you can get the carbs close but not perfect also fold the lines over then start your bike and slowly release the lines if one carb is high it will suck all the fluid into your engine be ready to turn your bike off
