    Namura Technologies Pistons

    Are these pistons any good? Im rebuilding the RZ and this brand as a kit is much less than the wiseco.
    Im rebuilding the motor then putting the bike up for sale.
    Im moving up to a Duck.
    The add states:

    All Namura pistons have molybdenium/teflon skirt coatings. The advantage of this is:

    Least possible resistance
    Least possible wear
    Extends the life of the piston
    Namura Technologies pistons also have a anodized dome for superior heat resistance, longer life and super high silicone content for added strength.

    Hey Mick,How bout some picks of the RZ before you let her go.I'm afraid to ask how much,last time I did that I bought Yellowbird from Joe about 10 mins after he posted it was for sale.Guess I'm safe for now,broke from winter.I'd guess those pistons are hyperteutectic due to the high silicone content(kinda like Pro-x with candy coatings).High compression and/or lots of timing I wouldnt run them,might have a tendancy to granade.I dont know the specs on the RZ,IMO probably ok for selling,but not for keeping.Hope this helps

    After looking at Numara's,I just realized you could get Wiseco's made for Vito's forged super stocks good for 6-8 hp for 200.00 for the kit with wristpins and bearings,is well worth the extra 60 bucks.I might have some used .030's if you want me to look.

    I have been busy as all get out. This weekend is my first 2 day in a row off of work weekend. Chemical plant shutdowns are killing me.

    I have not forgotten about your garage if you havent gotten to that yet.

    Steve thanks, Im thinking about going with the Wiseco simply because of the knowledge of name.

    I want to fix the RZ correctly so the new owner wont come back to me and say i ripped him off.

    Unfortunally the piston loss scared the cylinder so I have to bore the thing out. The pistons are stock right now.

    Vito's forged Super Stock Pistons are basically modded pro-lites,machined down on the top of the piston,on the exhaust side to match the port.It allows the piston to mimick raising the exhaust port 1.5 mm increasing mid to top for 6-8 HP.I'd like to see some pictures,if you dont have a buyer I might be interested

    Yes Im still running the oil injection. I disconnected it but it became a pain in the ass to carry and add oil at each fillup of 2 or 3 gallons.
    I installed some new clear injector lines to keep an eye on the oil in case of any air bubbles.
    Im running stock carbs and some aftermarket pipes.
    Here is what the piston that I took out looked like.
