How do i find vacume system on 1984 550 gs suzuki

SOURCE: M50 internal kill switch?

That's the Suzuki SASS sensor which stands for Suzuki Anti Squid Sensor which tells its owners to stop popping wheelies on their 700 pound cruiser.

Hi
Sounds like someone has customised your bike - does it have a RH switchgear?
there shd be 3 connectors for the RH switch in headlamp - a 3 pin & 2 singles, the 3 pin has 2x orange/white + 1x yellow/green, this connects to 1x orange 1x orange/white +1x yellow/green wire which are for the kill + start
The singles are 1x orange/green + 1x white (loom side) which go to 1x orange + 1x white respectively, these are for the brake light
If you are keeping the kill sw then its only the yellow/green wire that can be discarded.You can also follow it back to the starter disconnect sw - junk that - keep tracing it back to the starter solenoid & junk that too. If you want to keep the electrical accessory output terminal then connect that straight to the battery or to the orange wire from the ign sw to the fuse box. You can also junk the thick wires from the solenoid, 1x to batt + 1x to the starter motor
You can junk the starter motor too ( 2 bolts then pull away from sidecase & up at the rear) but make sure you block the hole up!
If you want to bypass the ign sw then disconnect the 4 block from it & jump the red to the orange & also the brown to grey (for lights etc)
Good luck & ride safe

200° is quite warm...
If the engine wont turn over, probabily you have a bad battery, a bad starter or a bad starter relay, or bad connections.

A hot engine has more compression. If the full battery power doesn't reach the starter it won't turn over...

SOURCE: suzuki 1400 intruder wont start.. just clicking noise.

It's most likely the connection to the battery. The screws dont tighten in well and you get the famous clicking....I replaced the stock philips screws with a hex bolt and after two years of trying to solve the problen have been starting everytime for the past year no problems. Another gie away is the intermitant starting problem gets worse when wet.
