Sorry I can't give detailed breakdown. What happened was I did one long trip to validate the motor, and all seemed fine, then suddenly it turned oilburner with one tank of gas. ( I had the same experience on my KLR , instant overnight oh-shit-something-is-very-wrong-in-the-bore-now-suddenly ! )
Both scenarios direct relate to engine damage consequential to either air filter falling OFF unnoticed ( eeek ) on a dirt ride , or the tell-tale of a home-made botch job airfilter !
Anyway, as soon as the mill chewed 500ml/1000km I committed to a total top-end rebuild , so clutch, timing chain, bore, valves, all the polymer seals, etc etc, were done in one big project , which I have to admit, I wimped out on and gave to the Awesome Mr Claus Tyrzyk in Killarney Gardens to take care of. The final bill was in the order of R8000.
The parts we tried to source directly, but just like the rebuild on my wifes 650 Savage , it turned out that Suzuki's prices were not bad ( remember, I am a recovering BMW / KTM owner ! )
We placed a consolidated order on Suzuki SA and the parts arrived from Japan in about 2 weeks, good service for a bike nearly 20 I'd say.
You have SUCH a good deal on the purchase price of that bike , that you must be prepared to spend a few more grand to make it LEKKER !!!
It took some willpower not to intercept that scoot and pull it out from under you for myself , when I went to see it !
Clutch plates are a little over R100 each I think, the steel ones are around R90 if you have any warped ones.
The only rip-off parts were valve stem seals , but then a huge markup on a small item can go unnoticed and not worth the sweat.
Cam chain is R400-R450 but your chain should be good, balancer chains don't really take strain and last the distance.
I'd do the valves and balancer chain and clutch , get the carb close, and take it for a serious ride to confirm the bore is in spec , then build a bike around a good engine.
Whats the condition of the air filter ?
