Hi,
I was giving a stock answer while actively searching on another page for the bigger kit. I was talking more of an expense point of view. It does sound very Yamaha cc but definitely worth a look.
My 300 is Luke's old Rolfo from this site. I am hoping for huge gains but its not together yet.
The engine is:

crankcases flowed etc,
cylinders ported as far as possible.
VHM heads
Wiseco pistons
NX5 and programmable total loss ignition.
PWK 39's
Ram air
Transmission changes etc.
Race fuel
Other things that I can't remember


I only mention HP to get a bite from somebody. He never notices; I have quoted 90+ before. I have no idea where it will end up but hopefully should be pretty good. I am taking it to a stage beyond Tyga's 300.

20 years ago I fitted a Malossi 170 bore kit to my ns125 so you never know, there could be something to the story. We all live in hope.

The 20 minutes riding it before it blew was great fun. I wondered what the brass thing was in the box; now I realise it was a needle and jet. I was very young.

75 from a 250 is very impressive.

Have a good one Very Happy
