I own a ktm duke 200. After using for one year or around 6500 km there was a ticking/rattling sound coming from the engine head, like there is something lose. So i when to the ktm service centre in shillong, meghalaya, and told the mechanic about the sound. At first the mechanic check the cam chain tensioner and said it was okay and said that the sound was from the engine head. But he doesn't seem sure about what exactly the sound was from or seems like he doesn't want me to know and told me i have to change the engine head including the whole set like the valve... Etc, etc. But then again, the mechanic told me it's not a major problem, and that i can still ride it without repairing and won't cause any problem accept there will still be sound from the engine head... Seriously?
So do i really have to change the engine head (The whole set)? Is the mechanic in shillong ktm service centre really capable of his work? Is this normal in ktm motorcycles??
I haven't repaired my motorcycle because i couldn't really trust the mechanic in shillong ktm service centre, and i haven't ride my motorcycle since then.
And another thing the mechanic in shillong ktm service centre, they only wanna repair minor issues which is not hard to work on. There are more than 20 ktm motorcycles piled up in front of the service center for engine repairing and they only work on motorcycle with minor issues. I could go on but lastly... I would like to say... I'm a big fan of ktm motorcycles, in fact it's the best bike i've ridden so far, but very very very disappointed with the service center here in shillong, meghalaya.
A humble request... Pleaseeeee resolve this issues in the service center.
