Hi again,

stripping my yzf 426 since the history is unknown. I will be replacing the cam chain. I have seen prox and ybn cam chain on evil bay. I also found one from wiseco which i assume is best? Any comments or recommendations?

I have another question...is the cylinder bore nikasil coated? (hard chrome?) Or is it an ion sleeve in an alu casting? i am seeing "oversize" pistons on offer which i dont think work with nikasil?

thx

You can over bore the stock cylinder up to 3mm, but it requires replating it. There are no oversize pistons from Yamaha for wear.
