cb350 vacuum gauge connection
« on: June 13, 2008, 05:54:52 PM »
I just got my morgan carbtune in the mail today, and before jumping into this blindly I had a quick question. I haven't spent a whole lot of time working on the carbs, so I'm not completely familiar with them. My dad and I have been working on this bike together, and he rebuilt them one day when I was working so I really never got any time to learn them intimately. However just looking over them really quickly, I can't find an obvious connector for the vacuum gauge. On the pictures of the 750 carbs I've seen, its very obvious and easy to get too, but mine don't have such an easy to find setup. So where can I find this, and does anyone have any tips before I start.

PS: this is a 350four, not the twin

found it. I was looking on the carbs when it was really on the intake manifold. I'll take a picture and document the tuning when I get around to it.

It's pretty easy syncing these bikes, just don't get obsessed with having all 4 colums exactly the same. If they are close, you're done.
I sync once a year, it takes me 10 minutes. I don't even need to hook up an exteranl fueltank, you can do it with the fuel thas left in the carbs/lines. That's better than messing with it for 2 hours and never doing it again.
And make sure the tubes dont hit the headers or engine, they can melt (don't ask me how I found out) ;)

And be sure to put a fast moving fan on the engine so you don't overheat it...and open the garage door... ;D
