Yah, dont check the oil with the bike on the sidestand, that's prolly the problem.. You have to have the bike upright, so have someone hold it, or sit on it and check it, also don't screw the dipstick back in, just set it in there and pull it back out and check the stick. Oil capacity with oil and filter change is 3.9 US quarts I believe.. And it really should only be overfilled if you are doing 2 mile wheelies, or 1000 foot endos.

 

I use Amsoil. I'm an independent dealer for AMS. Its the best oil I have ever used. I became a dealer for AMS because I wanted to buy AMS products at wholesale prices. Check it out for yourself but I will never switch. I only have to change my oil once a year or if I wanted too I could change it every 25,000 miles.

 

From the F3 service manual ...

Engine Oil Capacity
w/o filter change: 3.6 qt
w filter change: 3.9 qt

Recommended engine oil
SF or SG SAE 10W-40

I like MOTUL 5100T synthetic blend - about $25 a gallon. I also use the Mobil-1 M110 oil filter - about $10. It's an inch longer than the stock filter which means more filter area. It's kind of a tight fit with stock headers though. The Mobil-1 M108 is the same length as the stock filter (2.5in) and fits easier.
NEVER use a xxW-30 weight oil in your bike. They usually contain friction modifiers.

The track bike gets Wal-Mart 10W-40 and a FRAM oil filter, but I change the oil after each track day.

 

I like to use Repsol conventional blend for break ins.At the second change about 3k I use the repsol 10w-50 race all year round. I swear by it good stuff![sm=groupwave.gif]
