Hi everyone, so I finally was able to get a hole of a bore gauge and micrometer to measure my cylinder/pistons. Cylinder is in spec and almost perfectly round.
Pistons however, not so much. pistons are about 0.015" sloppy...
So I'm going to replace the pistons and rings and get her back up and running. I've found some single NOS pistons on ebay for a little more expensive than the mikesXS pistons. I've also found a kit from JAPAN, with pistons and rings for quite a bit less.
Anyone have experience with aftermarket pistons in these bikes? Most aftermarket products are pretty good quality now, but I'd like some opinions.
I can get the piston/ring kit from Japan for 134$ canadian http://www.ebay.ca/itm/74-81-YAMAHA-XS650-STANDARD-SIZE-PISTONS-SET-2-PISTONS-447-TYPE-10-XS650PS/141952967438?_trksid=p2050601.c100085.m2372&_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20140211132617%26meid%3De4f0b1fe012a4cab8a05fa9cc72df830%26pid%3D100085%26rk%3D3%26rkt%3D4%26sd%3D381529162747%26clkid%3D4590868447575093297&_qi=RTM2247627
Mikes XS pistons for 150$ and rings for 86$
or NOS pistons for around 240$ and rings for 68$
I think its clear that between the mikes rings and OEM ones I would definately get the OEM.
But can anyone speak for the quality of MikesXS pistons?
thanks!
