Changed oil at 54500 oddo. Drained Valvoline after 1100km oil was not in good condtion. Manufacturer guaranteed for 2000km interval of drain period but condition after just 1000km was miserable. Now poured Liqui Molly 20W 50. RS. 800/= Per Liter. Like every oil when its new, bike is giving good output. But waiting for initial 300 400 km and after that results and condtion of oil.
