What oil for my F4i

[*Gswitch33]

Just dump in the synthetic and call it good. No need to do anything special.

WTF

i just changed my f4is oil and it took 3.2 or 3.3 qts and the glass window already showed oil up to the top line. i did change the filter..

how come u guys are putting 4 or 4.5 qts? am i doing something wrong?

They're filling the engine with oil to the top of the glass, so the oilpump doesn't run dry and by that blow the motor, even when your at bp for a looong time.

it's a safety measure for a stuntbike, so it always gets the oil it needs

i thought from nothing the f4i hold like 3.7 or so quarts?? maybe im wrong, but i havent overfilled mine for stunting and i use really close to 4 quarts, i swap out oil filter and when filled up with oil start the bike to let oil run through and then fill again to the line etc...sometimes iv used more than 4 quarts and not even for stunting yet as long as your bike runs good i wouldnt be worried...

final answer!

[sikgixxer750]

buy the gallon of honda gn4 10-40 and pour it all in. It costs 20 bucks for the gallon so change it often and you should be fine. Its cheap enough

Honda gn4 is what the bike was designed to run with, so I go to the top of sight glass with it. Just dont put some cheap oil in. My bike ran like crap when i got it, guy before me just threw any cheap car oil in it...
