I am so sad to hear the noises the engine creates, it does not look like a new bike now, been planning to go to Honda Regional Office but havent been able to get time. Much too busy with my office work and family.
Inshallah tomorrow i will go to them and update u.
About the carb normally it doesnt have anything in it provided that you use good quality fuel. If it gets anything in it, there is a drain screw in the bottom of the carb, My mechanic used to open that and let the petrol drain from it, then he removed the petrol pipe from carb and used the air pressure from inlet of the carb and everthing came out. No need to open the whole thing. Han there is an exception when there is something stuck in the needle valve, they have to open the whole carb, and its symptom is that you bike gets over in idle position.
However every mechanic has his own theory and succesfully justifies it. God know what they do to our bikes.
Han if you ever happen to go to Batgram or Basham, These cities are on Karakoram Highway about 150 to 200 KM from Mansehra.
I was in Batgram last saturday with family, and i bought a Goat Set 40 pcs, and Spanner, and a stylish hammer in only 500 Rs
