Radiator Hoses and Spark Plugs

[artbone]

When my second Vision arrives I plan to go through it completely and one of the things I want to do is change the coolant and hoses and recondition the whole cooling system. Who makes original style hoses for the XZ? I've looked at a company called Samco and they have many obscure bikes listed but no XZs.

Also, what brand Iridium plugs are recommended? I see that Denso and NGK make them. What's the consensus on which is best

[lexx790]

My iridium plugs are NGK and are excellent.
They are the first iridium plugs I've used so I can't compare.

[fret not]

Both NGK and Denso are good Japanese companies so most likely not a lot of difference between them.  They will meet technical specs.
