Suzuki 2 Strokes

HI
could anyone please tell me if there is a simple way of doing this without taking the clutch assembly and alternator apart/off? In other words, is there a relatively simple way of taking the engine unit out and replacing the seal on, what i assume is number 3 piston end of the crank? i.e. can the seal on the crankcase end be replaced with the crankshaft still in its rightful place?

If not, then i would guess that the entire clutch assembly, kickstarter, ignition disc on one side - and the alternator, clutch and gear assembly on the other has to be removed entirely before 'splitting' the cases....yeah?

If anyone has a step-by-step guide, i would be grateful. My maintenance skills are not bad (have rebuilt engines in the past) but i am also the king of unfinished projects and i dont want to start it, then leave it cos there was something complicated which i hadn't figured on encountering. I have the original suzuki gt380 manual but it's a big vague in places.
any advice appreciated

Hi there, is the engine burning the gearbox oil? Or does the gearbox oil smell of gasoline? If not, the seal might be OK ...

I have never tried it, but I do not think it's possible to change the seal without splitting the crankcases ...

no, the gearbox oil is being sucked into the chamber and being burnt. that's for sure.
