Hello All, First post. I picked up a couple of invaders (80 340 and 79 440) for $300 a few weeks ago and have been wrenching on them. This site has been awesome. The 440 carbs are Mikuni VM 36's and have the vent tubes attached to plastic adapters on each side. Do these plastic adapters back out of the carb body? I dont want to soak any plastic in the carb bath. Doing new crank seals, fuel lines, all jets and rebuilding fuel pump with kit. This site has been very helpful with just using the search function. Also purchased a Kawasaki manual for both. Thanks in advance.
