Well if it is possible its a bastard. the bearings are in the actual casing so changing is nie on impossible or costly when a new engine is cheap enough
I guess I could just let a decent garage do the bottom end for me if its very hard on 4 strokes, and yeah your right the 180 will probably last longer than I need, but I could swap engines with a 200 anyway just so I can muck about with the 180
have you read the manual? of course you can change them.. there not cast in place. infact there easier than a 4t as there not heat seated
gonna say what kind of engine would that be ? be like having a kettle and not been able to re-fiull the water when you used it :rofl:
