Strange that you should put up a dyno graph, as I tried to do the same thing with my PGM post, but got a file to big notice, 256Kb or something similar. So what is it, 63hp rw,@ 10.5 and an nice fat and flat torque cure that also peaks very closely, sounds very nice as does a lap record, sweet. If I were to achieve similar figure I'd be more than happy. Thanks Andy for the PGM info, I'll get them both tested, 1 should work I hope.
I have had this conversation with my RGV mate it goes like this, So a sh*t RS 125 will knock out 35 h.p., a reasonably good one about 40plus, a really good one will do 45, then there's the A & B kit bikes and the timebombs. so if you take 1995 NX4 engine and transfer the porting dimensions, head profile, carby and chamber over to an NSR 250 motor, where are you going to end up on the scale of Horsepower as mentioned above. Say the crap one that only does 35, that's 35 x 2 = 70 ... our conversation ends with starry eyes and a certain amount of anticipation.
Now even if that's not rear wheel horsepower for some reason and you loose 13% through transmission loss, @ 9.1 h.p., then your still left with 60.9 h.p and there are not to many RS125's out there that are as rubbish as 30 h.p. .... we are possibly mad, but it's fun
