Engine oil level goes down

[burkbuilds]

I wouldn't be surprised if you are just seeing the "break in" period on your bike. A lot of motors tend to burn a little oil when new or newly rebuilt until the rings and valves seat. Keep an eye on your oil levels and you may see that you will start to use less oil over the next couple thousand miles. I'd also recommend that you have your valves checked and adjusted. My GZ needed that done pretty regularly about every 4-5000 miles. I always used Suzuki's synthetic oil in my GZ except for one time. That time it burned oil but when I used the synthetic I never had a problem with it burning oil. My bike already had about 1200 miles on it when I bought it so it was probably already "broken in". Maybe you might give the synthetic a try if you continue to see oil consumption and see if it makes a difference. I know the synthetic is more expensive but the GZ doesn't take much more than a QT at oil change time.
