[Resolved]  Yamaha Gladiator 2010 Model — engine shuts off while running

Address:

Hyderabad, Andhra Pradesh

I have purchased yamaha gladiator in 2010 Feb from Perl yamaha Y-Junction Kukatpally. The byke is good in all aspects. But after every[protected] kms the problem starts till cervicing is done. The problem is when i start the vehicle and move up to 3 to 4 km the running is smoot, after 4 kms when i slow down the vehicle and apply the clutch the engine shuts off, after that the problem repeats when ever i slow down the vehicle. I observed this is happening when engine gets considerable heat. So if the give the vehicle for servicing(oil change and general servicing) the problem will be solved. Then after 2000 kms the problem once again starts. Now i am in 3rd serviceing period. So this problem forcing me to do servicing before its actual servicing period. I am giving my byke at yamaha service center only and they are using YAMALUBE-4T-20W-40S. The service man told that after every 1800 kms the engine oil gets thick so the engine gets heat heavily and then oil circulation becomes difficult, thats why engine getting off. I don't know whether this is valid reason. I always use Indian Oil Petrol only and in one same petrol bunk.
It is difficult to change oil for every 1800 kms. It will increase my maintanance cost.
