[COLOR="#000080"]From my thinking valves+rings replacement is not due to GLI type usage
Its cause is engine oil brand change continuously
I was read in your earlier posts your were using two types of oil in your bike,s engine one was zic & i think other was total
Same problem has happened with my bike at 28K on odo because of engine oil brand changing i have changed continuously 5 types of oil in my bike
I was warned strictly by my a friend of suzuki mechanic to be stick to one brand only whether it is anyone
But i have never listen to him/COLOR]
