Bought SZ-R in march 2011 and was very impressed in the initial days. First 100 KM drove below 50 KMPH and got mileage of 45 KMPL. After that I noticed that the engine roars when the speed crosses 50 KMPH, the same was reported to service in 2nd and 3rd services but nothing good happened. In the 4th service stressed much on the noise, Yamaha service personal said that the noise is arrested, but when I tested the found that the noise still exists. Other bad part is that my gear shifting has become very hard particularly while reducing the gear.
Now I started disliking the bike and the YAMAHA brand/showroom, and don believe in this free service, I think its pure cheating and at times even doubt if my engine oil is changed even after billing me for the same. If some has a solution for engine roaring sound please let me know.
My bike is now due for next free service and this time planning to change the service centre. I am from chennai so any chennaiates can recommend me a good YAMAHA service centre to set my bike right.
