1982 XS400J DOHC - 'Davey'
Bike was fine until I changed the oil now it's cranks no problem but no start. Spark is mint, brand new plugs also, just checked them to make sure they aren't lemons, back pressure seems right, compression blows my thumb off with me applying good force so I'm guessing about 115-120psi, oil I used is motomaster 4 cycle sae 20w50, I always use the same stuff, coils are operating as intended, battery is mint, I take it inside after every ride, made it easy to do so, solenoid is a brand new OEM (legit factory wrapped with a yammy seal, I got lucky on an auction), all my interlocks are bypassed and done so professionally. All I can think is carburetors maybe but would they really just magically clog up in the one hour between when I started her last and when she told me to go fuck my self?
