Does anybody know what I should be buying to attach the vacuum guages to?

I know you take out the screw and put in a barb fitting, but what size is the thread?

pipe thread?

I have a chance to go to the hardware store today but I am at work so can't measure it myself, a quick answer would save me a fairly long trip, thanks!

From what I've read, most Suzukis use M5x1. Mine uses M6x1. No hardware store will have anything like that. I ordered adapters from Z1 Enterprises.

It's a standard 5mm X .8mm thread.

Not something you'll find at a hardware store, but you can order new ones from http://z1enterprises.com , http://crc2onlinecatalog.com , http://denniskirk.com or http://www.carbtune.com/

What are you using to sync your carbs? It should have come with a set of these.

well I was hoping, but it turns out that the Manufacturer has an OEM only deal going, can't sell to joe public.

Its stupid as the store sells m10x1 and up, but under is all OEM only...

If you can get bolts from the hardware store to those specifications, get the ones with an allen head. Buy some tubing that will snugly fit these if the vac lines for your kit don't. You can probably stretch vinyl tubing to fit your gauges.

Drill bit.

Put your bolts in a vice (on the heads, of course) and drill through them (buy a few extras in case you mess up).

Grease the heads to make a better seal when you put your vac tubing on.

Ta-da.

Haaa, sweet. I was actually contemplating exactly that maybe 5 min before reading this...

I am going to pick up some allen head ones for the intakes anyways, I should probable make sure I get the right ones (m5 or m6)

Thanks!

There's something vaguely familiar about this valve.
