In the middle of swapping the 3LN on my FZR. Noticed that the new engine is a different 3LN. Pretty sure I'm replacing a newer one (3LN3 maybe?) for an older 3LN1. Old broken motor has the screwable oil filter on the side, new one has it on the bottom. I notice the one with the filter on the bottom has some wires coming from the filter that are different to the new one. Anyone know if the wiring looms for the two engines will match? The connectors are a bit different on some things. Any other compatibility issues I might run into?
