1990 Yamaha XT 600 E Questions & Answers
Hard starting, dies when throttle opened quickly.
Sounds like a kill switch is going bad or ignition wire getting grounded along the frame or elsewhere. A bad ignition switch can do the same thing. Check the side stand kill switch if your bike has one. Check all electrical connectors. A loose or dirty connection can screw up the works.

Hi and welcome to fixya,
Hi
and welcome to fixya. The intake manifold should be taken as the last
option. Basing from your description of the problem, the most probable
case is poor firing. You will need to do a full check on timing, fuel
mixture and spark.
Cutting out can be caused by poor fuel. In
this case, there might be water on the carburetor reservoir. Drain the
carbs. Until the muddy or rusty residue becomes clear. This procedure
doesn't require you to open the carbs but if you want to be sure. You
can do full carburetor cleaning meaning you clean the jets as well.
The
rattling noise can be caused by timing. The timing chain maybe loose or
there's a failure of one of cylinders to fire. Since you mentioned it
runs fine again, im guessing there's a problem with the spark plug. Make
sure you have good plugs. I recommend replacing them all at once to
narrow down the problem. Even if the spark plug seem to be fine, the
copper core could have been corroded. I recommend replacing it if its
more than a year old and have been extensively used.
Make sure
you have good fuel and air mixture. It usually is 2.5 to 3.5 turns out
from a full close. but if you haven't made changes to it yet, let it be.
This will save your plugs from wearing out too soon.
The leaky
intake manifold can cause lose of power, and will definitely lean out
the mixture. Physically check it to make sure there isn't any cracks or
big holes that can let air in.
I hope this info helps.
