OK, back to business and let's leave the farkles for a while, thanks to all for the good suggestions and comments. (Answer for Channing about the weight..The only time the bike has been on scale was at Toronto airport cargo terminal and the scale showed 442 kilos. But then I had all my riding gear etc packed in the cases, but gas tank had only one gallon of gas...)
1) The clutch push rod: The darn thing was pretty tight to pull out. I really had to squeeze hard with pliers and of course I left marks at the end of the rod ( I guess that part can be smoothened with a file...) . The clutch end of the rod looked as if it has been warm at some stage. See the pics.
2) Throttle cables. The hint that John gave about Dave's pics was really valuable!
Even though I still don't have the upgrade part to the handlebar I already installed the new cables by following the excellent documentation by Dave.
3) Throttle bodies. While looking at Dave's Picasa albums I found there another interesting topic: LT Clutch Repair http://picasaweb.google.com/dtnicks/LTClutchRepair
I'm not yet at the stage of pulling my gearbox out as I told before but instead I'm fiddling around the throttle bodies and I have the same symptoms as Dave had with oily dirt around # 3 cylinder intake area ( with #3 I'm referring to the second cylinder from the rear of the bike, I don't know if it is correct nr...)
If you look at the pics you can see a lot of oily junk particularly around that #3 throttle body and also the intake box is particularly oily at the same spot.
Now I wonder...As you can see in the last pic there is a small crack in the Y-joint of the crankcase ventilating tube - pretty much in the same area as Dave had. However, I'm not 100% sure this crack is really through the tube. But if there is some pressure in the ventilating tube, perhaps the oil can seep through it...
Anyway, I will replace the tube or perhaps I will upgrade it with copper or stainless steel parts or whaddya guys think..?
One more question to the "been there done that" pros: The crankacase ventilation tube was quite easy to peel off from the engine block with a help of a flat screwdriver but how have you put it back???
