Searched this topic for awhile and can't find anything useful. I noticed my shifter seal on my 00 426 was leaking. No big deal, replaced with a new seal and did a new oil change etc. Oil level is in the middle of the crosshatches so that's good. Now it doesn't leak ( that i know of ) when riding but after it sits for a day or so it starts leaking again and my oil level sits lower than normal. The shaft does not look bent and isn't scratched etc. If I start it for a minute and check the oil, the level is back to normal and it doesn't leak for a day or so of sitting. It seems that the oil systems have 1 way valves and maybe 1 is bad and allowing the oil to drain from tank to case while it sits and may be causing this. Any ideas Grey?
