Just wondering if anyone has ever checked or compared the profile of a Cruzinimage piston against a genuine Honda one.I'm reading some really negative stuff about aftermarket pistons and especially about the quality of Cruzinimage piston rings, notoriously the 350 four ones which are reportedly very soft and wear extremely quickly. Reports I may add that come from a very experienced mechanic and certified Honda/Kawasaki mechanic trainer, not the sort of person to shout wolf you'd image.I've seen an image where 2 pistons are joined on the same gudgeon pin, so they sit side by side and it's impossible to get them misaligned as that's exactly where they'd sit on the conrod, the rings were in different positions, the crowns didn't align or even look the same, Hondas are normally flat and the aftermarket was really domed, this would seriously affect the compression.Another image of Cruzinimage rings after less than 500 miles, both a before and after picture showing ring end gap, it had doubled in less than 500 miles, which is worrying as a lot of members have fitted these kits.Not trying to scare anyone here, just wondering IF anyone had done a comparison, especially of the piston. Just curious to see how they compare.
That's a bit worrying considering I was going to buy a set for the rat bike rebore! Are there any other makes apart from Honda? I think I used an IMD(?) Piston kit in the 250RSA, hopefully they do a set for the 400/4. Do Cruzinimage makes pistons and rings for anyone else?
Oh I'm loving reading this thread!

Do Cruzinimage makes pistons and rings for anyone else?Possibility https://www.ebay.co.uk/itm/255571788913 but a little pricey.Seems to be only pistons, but 6 available https://www.ebay.co.uk/itm/285149322144 Both sets 0.25mm over sized.

Forgot to say that Cruzinimage rings are Riken, which is what Honda use.

I'm pretty sure my top ring had an R on it.
