i just finished breaking in a nsr today. i noticed the bronze nut size has been changed from that stupid "middle of the road" size nut to a 7mm nut. what this means is that a normal wheel hex wrench can be used on the nut.

HAVE YOU TRYED USING A 7MM NUT OR A WHEEL NUT AS A REPLACEMENT? it may look hack but it mught work.

small question;

how easy/quickly did the nsr owners break in their engine? i found mine to be broken in within the 5th tank! i idled it for 4 tanks, and drove it around for 1.
the NSR is a cast piston as oposed to machined correct? pm the answers if possible i hardly check the engine thread.

thanks
