I bought Suzuki GS-150 almost a month ago. Since the start i wasn't very careful about driving it on slow speeds during the running period. I accelerated it upto its max i.e. 110 Km/h speed that i heard is very dangerous for any new engine. Fortunately my bike didn't halted, jammed or ceased. But for some days i am observing a strange voice coming out from some where the top of engine (the head or whatever you call it), the voice is like "hiss" or "Sarsarahat" as you call it in plain urdu. I have recently changed the first oil on 400 Kms. The oil i used is Suzuki 10W-40. Also my old cd-70 used to make such voice when i didn't got it tuned for 2 months or more.
I am very worried about this voice and want some highly expert feed back about this condition. I also went today to the dealer and was freaked by seeing another GS-150 standing there whose engine was seized on just 400 Kms, that guy also dragged his bike to 110 Km/h speed
Experts and seasoned riders please respond to my issue and what should i do in this condition. Extremely worried about my baby
