Iv had millennium technologies +2 my gen3 bore with a nikasil coating & it looks like they fucked it up & I'm going to war has anybody else had similar problems with a Bad coating from them?
Thanks buddy but i did all of that except using calipers? Do you mean a vernier gauge?If you ran it, I highly doubt they will do anything for you.
Couple tips for assembling top ends (I have done many and ruined a few)
FIRST, wash the machined parts in soap and water to remove any honing grit. The bores should wipe clean with a white cloth.
SECOND, measure piston to bore with calipers.
THIRD, LUBE bore and piston with engine oil.
FOURTH, set rings in bores using piston to square them, and check gap size
FIFTH, install rings onto piston, paying close attention to gap locations per directions
SIXTH, LUBE rings heavily in engine oil
LAST, Install piston assemblies into bores
Your pics look like scuffing from debris, or lack of lube causing debris. Run a straight hone down the bores lightly and see how they look (use lube). If you can still feel grooves you will need to replate. What do the piston skirts look like?
ATF is a synthetic based fluid? Or am i wrong i used mineral oil for running in as a synthetic will glaze the cylinders before the rings have bedded in?I had an issue with them and they told me they had no idea what happened....
The first time I put my motor together I did not clean the cylinder walls with ATF fluid but I used WD-40 the second time I built the motor I used WD-40 but then used Red ATF fluid and I got SOOOOO much more shit off the cylinder walls.
Cleaning the cylinders with ATF is VITAL!
Thanks man:angryfire: US Chrome are the people i should have realized when MT offered me such a good deal:headshake:US Chrome is the only place I'll go to from now on.
MT did my zx9 cylinders last year and i put 100 miles on the engine before it ran into issues and i'm very meticulous about mechanical stuff and also have a degree in engineering with a minor in automotive engineering (in case anyone questioned my assembly procedure).
I have literally never heard anything good about them since I forked over the cash 2 years ago....
Sorry you didn't hear this sooner, but as mentioned, no way they'll do anything now that the crank has spun. Sorry man.
