Remove one bolt, center back, under front of seat (remove seat first)

Slightly lift back of tank, and slide rearward, off rubber dampers attached to each side of frame at front of tank.

The only vacumn lines on a Maxim 650 is the small line from the fuel petcock that turns it on when there is intake suction. It can be connected to any intake manifold But is usually connected to cyl. # 2 left to right. The 4 vent hoses to the carb tops just hang down the back of the motor.

Chances are the new bars are a bit taller than the old bars. It sounds like the taller bars are making you stretch the clutch cable. No freeplay at all in the clutch lever, Right? If the clutch cable was not re-routed causing the stretch, the only thing you can do there is get shorter bars or get a longer cable from a similar bike or have a custom cable made at the shop. The blinkers is just an error in how the wiring was reconnected.

Can I get a “very helpful” rating on this answer?

check the wiring, the voltage coming from switch and the flasher themselves

# 1carb left 0.04+or-0.04 inches mm 1.0+or-1.0 # 2 carb right 0.08+or-0.04 2.0+or-1.0 hope this gets you there

there is not much difference between those 2 engines. they are the same cc and both are in-line 4 cylinders.
