$3000 , sounds steep but I also have a list of reciets as long as my arm , nsr owes me about $14000 now , I got cheeper prices in the end from my local yamaha shop than from the honda dealer when I wanted to go local

prices were
barrell $ 1100 new with power valve and gasket
$500 second hand for bare barrell from bikes and bits(the only part I ever bought where the credit card bill was what I was quoted mind)
circlip $2.95
base gasket $21.95
piston pin $28.60
piston $211.00
ring set $107.00
head gasket $34.60

I had lots of dramas getting the right part first time out of honda too , normally took them 3 goes with the part coming from japan each time so getting your own part numbers helps , but hopefully for you the learnt from me
