Mitaka pistons

Got the cases split now finding the time to finish it. I was wondering if anyone has tried these pistons. They are available in the U.K. from PJ motorcycle engineers. Also wondering about Athena gaskets. Are these parts quality or usual aftermarket junk?

I know about the Athena gaskets and have used them. They are very good.

Thanks, ever heard of those pistons? I may just put a top end in it while im there. So far all ive measured is my ring end gaps and all 6 are between .019 and .023. The bore looks really good but I wont know for sure until I check the tolerances. it seems im getting excessive blow by.http://s578.photobucket.com/albums/ss22 ... 0_1171.jpg

All 3 pistons and bores look the same.http://s578.photobucket.com/albums/ss22 ... 0_1170.jpg

I believe they crack very easily...... I think Mark Hasse had one break while his RD was idling......

Yeah, they seemed too cheap to be true.
