I try to get stuff from ebay but a lot of the sellers won't ship to Newzealand

That's because they are cry babies  :cry:
The four stroke engine: That's one stroke for producing power and three for wearing the engine out.

I did notice that 90-04 kx500 uses the same part.
I wonder if you might find one in NZ..

A KX 500 is a very rare thing here and worth a lot of money.

I sent my cylinder off to be replated but they had an exchange cylinder I went for as it was a bit cheaper to do the exchange system and would save me quite alot of money as mine was cracked and need welding and the exhaust spring hook was also broken. I still need to pay them and they will send it to me.


Also pressed in the Pivot Works kit bottom linkage bearings with some sockets and threaded rod and packed them with grease.


I am totally broke now and don't think I can get any more new parts.

I still need a

Rod kit and get it pressed in.

Head gasket,

Inner clutch cover gasket,

Clutch leaver, gearbox end.

Possible clutch basket and plates.

Swingarm bearing kit.

Brake caliper seal kit.

Chain and sprockets.

Air filter.

Radiator hoses kit.

I was more worried about those pinholes, they arn't holes just clear spots in the resin but I was worried it was the reed wearing out?

it had this strange spacer witch I think is home made


It was probably made for extra clearance for a flywheel weight.
