Well I never thought I'd have to post something like this, but as the title says my bike lost compression and to be honest i have no idea what happened. I just did the 10km service (filter/oil and I recently flushed the antifreeze with engine ice.) ride my bike to the store quick to get something then ride back, it ran fine and didn't smoke at all. I go to take it out later in the day and it starts to smoke a little bit, a little white smoke but mostly blue smoke. now im thinking WTF this is a bike with less than 5k on it why is it smoking? I kill the bike, start it again and let it warm up until it stops smoking. I ride it up the street and it seemed fine and had full power in every gear. So now im about 2 miles from my house and i can hear the bike losing compression and im losing power as well. i pull over and kill the bike and behind me was a HUGE cloud of blue smoke. I check the oil and it looked nasty and almost like a choco milkshake, so now i immediately think headgasket but there was nothing leaking from the side of my motor. A friend of mine told me that it could possibly be the waterpump? He was saying that the waterpump is an issue on this bike apparently and he told me something about how the bike can lose compression if the pump fails (idk how true that is) does anyone have any ideas? I really don't want to tear apart my motor to find out that its not the headgasket! Thanks!
