I just bought the bike, and it had close to no oil in it. It smoked when i was test riding it and i was stupid and i still bought it. So i put about a quart in it and it still smokes blue smoke. It seems when it idles for a while it goes away but then i throttle and it comes back. It doesnt really come in clouds besides when i start it and unless i really punch it but i try not to because im still looking for problems it may have. Its a 2004 and i hope i dont have to do some serious work so soon ive only had the bike for a week and ive only ridden it about 5 times. What do you think? What are the possible problems?
