I bought my NSR a few months ago, MC21 the chap i bought it from said it had 60HP not the standard 45hp, Andy has ridden my bike as says it feels like 60hp (he did this when previous owner had the crank rebuilt) I think it has the M max box but thats all i can see (is this all thats required), How can i tell ive never riden a 2 stroke let alone a 45hp model to compare, Im going to look at the weekend to see if the PGM/ Gear wire/splice has been done if not will this work with the m-max box ? any way enough wibble anybody guide me to the right place to confirm its been derestricted? many thanks
