Took the bike to the dealership this Fri, I was kinda thinking that the spark plug is shorting once the engine gets heated up (confirmed and even apparently "fixed" by another dealership outlet last month here in blore, morons!)
Anyway, the dealership guys at the new place tested and said that the fuel pump was going kapoot instead, and was not pumping up fuel properly. Thought it should be just about cleaning it up, was shocked to hear from them that there was no way to fix the problem by cleaning up the fuel pump and it would need to be replaced. And what is the cost of new fuel pump? Just Rs. 7350 I am told! And why did this problem occur? I am told its because the bike has not been used much for a long period of time. I am told that this has happened earlier for some more Yamaha bikes too.

Now, I am pretty seriously pissed off, esp with the reasoning for pump getting messed up. It is is a race bike (have another for street), has some 5000km on the odo in 2.5 years with last year seeing around 1000km. Agree thats not a truck load of kms, but that is far from sitting idle too. And anyway, that is not hugely low kms for a race bike, this is exactly how race bikes r supposed to be!

I plan to take the issue back to Yamaha guys and hear what they got to say, but would like to hear if anybody else here has had the same problem. Or if the R15/Yamaha lovers over here got anything to add that I don't know yet...
