Sweet. how's the powerband?

I used Millennium on my cylinder when i rebuilt. Both are reputable companies.

the powerband is sick the pipe really helped out on the top end cause it had more bottom to mid before the pipe but once it hits it pulls and pulls ill be hittin our step up in 3rd wide open instead of fourth...ive been a fan of chromin the cylinder it lastes forever on my old 96 KX i went thru 5 pistons and not a score mark or anything the bore was still perfect

Yep. same plaing material/process, just different companies. typically the plating is used when the bore is aluminum. piston rings wont seal against aluminum, not to mention it would wear out the bore ultra quick.

yep ever since i did my KX im always gonna send my cylinders to them the onlything i just gotta take a tapper and retap the screw holes cause it leaves a residue in them but other than that im imprressed and will be sending them my 250r cylinder whenever i rebuild it this winter....they say they can chrome the skirts of a piston but idk about that kinda a waist of money cause i replace pistons about once a year i havent had a problem wit blowin up motors even though im purdy hard on them
