Ok so I aquired a mineralli moped 50cc head off of a V1 engine. It didn't have a head gasket.
Well compression test showed 30 psi. Same as with old head, it didn't even move when I put a cap full of sae30 in sparkplug hole and held engine vertically.
I'm so dumbfounded. I want this scooter to run. My friend has one that we welded a motion left Mopeds Cali pipe on and it rips at 45 all day.
I have a shit ton of experience with 2t 50-70cc Mopeds and scooters, worked at a motorcycle shop, and am in a moped club so I'm not dumb when it comes to this stuff, but I'm stuck. I need the stock head & head gasket that came with this bike. No o-ring bullshit.
I'm almost positive it's a huge head leak. Don't think it's my base gasket, piston, piston rings, or my crank seals. But it could be I guess, I don't think it's anything behind the piston rings because when I put oil in sparkplug hole it doesn't go above 30 psi.
