Anyone got any advice on tuning? I was running a raised compression engine (not very high, as the rings and valves are shot, so we were scared to go too far with comp ratios). Micron system, ignition advancer and dynojet/k&N.
I've now got a good low milage lump, which I intend doing the same with, but maybe using slotted sprockets to optimise cam timing.
Also, I though about a mild head-flow job, but not touching the valves themselves, as I'm concerened about reliability.
I don't want to sacrifice reliability, as my best ever finish is 9th, so I'm not exactly going to hit the big time (especially at the age of 37).
I've heard from one source that a 4 degree ignition advance is ideal on a tuned zxr400 motor, and from another that I risk blowing it up.

You will need to ring a tuner on the engine side there is so much to do and gaps and so on i dont even listen
I run a ignition advancer on my tuned engine and its fine but i know some tuners cant use them as it does advance the engine to much mine is 1 degree over what a spot on engine should be so i was told
Fit ram air for a start and there are lots of cams on the market now
Kent cams --- s.p. cams--- etc
good luck
