Pablo, I cannot figure out why they told you that, but I firmly believe that is incorrect. You should check the oil while the bike is on the center stand, and engine has been off for a few minutes. Please see the owners manual and service manual for more info.
The oil level tends to change slightly as the engine is running. At higher rpms, the oil level actually goes down slightly due to the amount of oil in the top end. Of course, this depends on the motor, the temp of the engine, oil viscosity and other factors. Overfilling the crankcase on a wet sump engine (which almost ALL engines are except purpose built dry sump engines in race cars) is bad, because the crankshaft causes excessive foaming of the oil. Heavily foamed oil does not lubricate well, causes excess wear, loss of hp/gas mileage, republicans to mate with democrates, and other bad side effects. There is usually some tolerance, but 1/2 to 3/4 quart too full on a GTS is probably the limit. Very frequently on a dipstick or in the manual you will find the phrase "never overfill !!" in bold letters. There is a reason for that.... PS: Yes, most automatic tranmissions are checked at idle, while warm, in park, with the engine running. -----Original Message----- From: pablo [mailto:[EMAIL PROTECTED]] Sent: Friday, May 10, 2002 6:57 AM To: [EMAIL PROTECTED] Subject: Re: dreaded oil consumption thread Sorry there�s a mistake: "I was told I had to fill oil and check level with engine running. There should be a minimum oil level through the window while engine running." Don�t try to fill oil with engine running. I meant just to check oil level through the window while engine running.

I was told buy Yamaha official dealer that oil consumption is a normal characteristic of this engine, which was corrected from 98�s Yamaha engines. They�ve stated that there�s no engine damage until oil consump. goes to half a liter per 1000 Km. (625 miles). I was worried about oil consumption red light�s frequent lighting. I was told I had to fill oil and check level with engine running. There should be a minimum oil level through the window while engine running. It implies to overfill a bit according to manual. But that�s what I did and forgot about oil consumption's light. Regards. Pablo.
