  • great video! helps me a lot.

    what are the gold things you use to hook the hoses into the intake? do the screw in or what?

  • The gold tubes go into the carbs check the Clymers manual for reference...

  • You've done it all wrong. You need to first adjust the screw on the valves so they show the same reading. Look at the start you can see the needle on the second gauge is way off the white box, same goes for 3ed and 4th gauge. 1st gauge is ok. Also use the white valves supplied with the kit so you can sync at idle.

  • Hey I have a CB350F and I need to sync the carbs, I have everything but the brass extensions, I plan on just making them instead of buying them being a machinist, Could you give me the dimensions of them? Length of the Short and long ones, and The internal diameter of the hole through it if possible. Threads aren't a problem i'll match them to the plugs on my bike. Thanks a bunch (:

  • Hey, nice bike..I have one just like it..Same color.. I just wish I had the stock airbox..

  • you need a Valve on each lines of your Carburetor synchronizer vacuum gauge , it will make the needles steady and easier to sync

  • Dude, where has this bike been! Stored in a time capsule??

    It is cherry!

  • Great! Now I know where to connect and how it works =)

    Good to know before I buy one.

  • Thank YOU! Every written explanation online makes it seem extremely complicated, but you show how easy it really is! Awesome!!!!!!!

  • you need to put in damping screws between the gauge and the pipes to eliminate the jumping of the needles

  • This person is exactly right. You gotta do it at idle.

  • U forgot about chokes in Your carb tool ;>
