Before I start removing stuff. Just gone to move the hybrid it’s only done minimal miles and hasn’t been started for at least 6 months. So totally rebuilt everything. As I’ve moved it loads of two stroke oil has poured out from the belly pan. I obviously need to remove the belly pan and have a butchers . Simple question any ideas as to where and why? Quick glance oil lines externally all seem in tact no splits etc, but stumped without removing cases etc. any ideas

I’ve had wet sumping before on old British bikes where the oil has bypassed a worn oil pump, this is a newly rebuilt pump in a rebuilt engine

It’s usually coming from the reed blocks through the hole in between the barrels and dripping off the studs underneath

2 options
First one as above. Non return valves at pump slowly pass oil and it seeps through the reed gaskets
Other one I had was the fibre washer on a newly built pump compresses and leaks oil at the bleed screw. Just needs nipped up. My bike did this
