Topic: High oil level when hot

[markreimer]

Thanks Steve. I appreciate the feedback. I may have to do the same. My 750 always had a steady oil level, whether hot, cold, just starting or after a long ride. After rebuilding the pump, top end and swapping my bottom end (had a cracked case) I've got this weird fluctuating oil level like you and apparently quite a few others. I guess as long as the tank isn't dry, or doesn't overflow, oil pressure is good, the engine should be happy.

One more thing...When I used 10W-40, the oil level could get a little bit lower after sitting a while with the newer pump. 20W-50 kept the level better.
When idling in periods of a minute or 2  with a few minutes to next start during ignition adjustments, oil level was lower despite a really warm engine. Level OK to top mark after a 20 minute ride and checked  direct.

Gasoline in oil will smell, very easy to detect. I have not had it in my bike, only old cars with bad automatic choke and/or extensive city driving. Oil level sank after a longer trip around 400km and really warm engine.

Thanks PeWe. If anything, I've learned that prior to my engine and pump rebuild, I must have had an unusually stable oil system in my 750. Never fluctuated at all! It's sounding like that isn't the golden rule. I'm going to spend the day riding instead of staring into my oil tank today.
