Hello, I'm in downtown and rides a 250. Lately, I am hearing 2 types of noises. First one is a squeeking sound, almost like metal grinding, from my front wheel when I start slowing down. Second one is when I rev my engine up to beyond 8-9,000 rpm, I feel like i'm hearing a rattle can when you shake it. Kinda concern for this bike was bought brand new, and I took it to the dealer at 1,000 for the scheduled maintenance service. I also clean & lube my chain after a long trip on weekends and also every 600km as recommended. I just cracked 4,600 km tonight, and I know my next scheduled maintenance is at approx. 6,000km. Any suggestion is appreciated.
