Jetting for race bike

Post by topfridgeman » Wed Jan 09, 2019 8:40 am

Hello guys,
I'm after a rough idea where to start for jetting on my zxr400 'L model race bike I'm building. It will be running a modified stock air box and a full aftermarket exhaust system. I have access to a dyno, so I'm really just after a starting point so I can order some jets.
Is there any benefit in advancing the ignition on the zxr's
If anyone has played with it? It made a big difference to my mates gsxr400.

Anyway, thanks in advance.
Colin.
