I have 2003 honda 300ex. I need to replace the left side of the crankcase. The manual says to take of the right side of the crankcase first but if i do that then i have to take off the clutch and a lot of other parts that are just fine. Can I just take off the left side and replace what i need or do i have to go through all of that stuff? Nothing on the right side is broken and if i have to pull off the right side then i'm pretty much having to dissassemble everything.
