Just a thought. I pulled the cap off the one check valve towards the rear of the bike, on my oil pump, and it just didn't look like the cap could be putting much pressure on the spring....the spring sure seemed to be a bit short to my eyes. I know that there isn't supposed to be much pressure on that ball...like a pound and a half or so, but still.....
So, I stretched the spring a bit, just enough that I'm sure it's being compressed when the cap is on/tight, and not just bouncing around in there, short of being compressed.
Since I'll be starting and running the bike on a regular basis now, I don't think I'll know if it's still wet-sumping or not...won't know if that made a difference. Took about two months last time. But I'm just wondering how many bikes wet-sump because the check ball spring is too short, or has lost tension. ???
Once again...just a thought!
