Yes plenty but can't see through the glass and oil light on. Just done an oil change, put 3.5 litres in light on, put another .5 litres in and light still on
From what you're saying there's now 8.5lts in there which is way too much and will completely fill the window. Drain all the oil out and put back the correct amount half of the window. Start the bike let it idle for a few minutes, checking for leaks. Turn it off after couple of minutes check the oil level, top up to half if required. Then do oil bolt gallery check as per the manual
The oil light level being on is a switch issue, often nothing more than dirty/carroded contacts. At worse the switch needs replacing.
