Personal preference would be to strip it down

@vtrn_raptor you can do it with really basic tools but you will need a flywheel puller and clutch holder to begin with , I definitely wouldnt change the seals withouth removing the crankshaft as you risk damaging it and it will damage the new seals in no time... its also good to have a set of new bolts , set of gaskets , good quality instant gasket 🙂

I can never understand why people won't just spend the measily couple of hours it takes to split the case. It really doesn't take that long.

People have done it in situe but i would always recommend splitting the cases
