Hi, i have a R33 with the usual minor mods (Exhaust, pod, cooler) and have tuned the exhaust cam timing on a dyno to get the best air/fuel mix and power.
Recently i changed the timing belt and even though i marked where the exhaust cam adjustment was, after putting it back together i notice it is running rich and using a lot of fuel. Also lacking that little bit more power i was able to get previously.
I have searched the forums and couldnt find any other previous post regarding the adjusting of the exhaust cam.
What i would like to no is, which way does the cam timing adjust need to be turned to retard or advance this timing. Also which will be leaner, retarding or advancing.
Thanks
