Jopiz:
I just rebuilt it. The packing has been used for about 20 min of driving time. The center tube in my muffler is perfectly in place.

When you checked the electrical stuff was it bench tested or swapped to another bike to check for changes.

Jopiz:
No official bench testing by Kawasaki dealer. Ignition coil is completely new. Pulse coil is just a simple coil that i checked with an oscilloscope. I also tested the CDI with a Hz generator and with an oscilloscope. I got exact readings what i was looking for. Stator works. Flywheel also.

Heres a couple pics of my spark plug. New plug is only for reference. The plugs are BR10ECS. I wiped any excess oil. The color is something like dark brass or bronze. I found it very strange. Click photo to get a larger image. The insulator is totally black.

Jopiz:
The bike refused to start. I took the carb out and disassembed it. Main jet had found its way out. Also the pilot jet was completely clogged. I put everything back together. It fouled one plug. It ran about 2 seconds and died. Smoked like hell. I started it numerous of times (runs 2 sec and dies). Until got it running. It burned all the excess oil out of the pipe and reved nicely. Much better than it used to be. I noticed the governor rod wasnt moving at all. I have to try and lock the KIPS in opened positon. Lets hope its the issue.

Jopiz:
Max RPM 6700. It just doesnt rev more. KIPS was locked in open position. 98 octane gas with Belray h1r 1:32 mix. Im starting to get frustrated. Doenst smoke as bad as it used to. d**n. I have to change the spark plug cap for non resistor model. Ill just try to eliminate these things. I got fuel, i got spark and i got good compression. What could possibly be wrong?   :oops:

Guys give me some ideas!
