Did an oil change in my F4i, now it won't start...
So about a week ago I needed an oil change. No problem, I've done it plenty of times this year. I drain the oil, had a really tough time getting the filter off even though I torqued it to spec, then started filling it back up with GN4 oil and a new K&N filter like I've always been doing.
So I put 3 quarts in, start the engine to fill the filter with no problems, then add more to get the level between the indicators. However I run out of oil just below the lower indicator. No problem, I'll just leave the bike alone and pick up another quart within the next few days then fill it up and start the engine and check the level again.
So I bought 4 quarts of HP4 oil, the sorta semi-synthetic Honda oil, since that's what I was planning on using in my next oil change, whenever that would be. So I topped it off with HP4 then started the engine... sortof. The engine started but idled rough and at about 1000rpms. Oil level seemed fine... I thought, well that's odd, so I drained a little oil thinking I overfilled it then started it again today with the same result. So then I drained all the oil and put my new HP4 in and measured how much I put in this time. All seemed fine and normal but when I went to crank the engine I didn't even hear any combustion whatsoever this time. It cranks over but it doesn't sound like an engine is attached.
What the hell did I do to my bike? The only thing I did differently was top it off with about .2 qts of HP4 instead of GN4.
