As I mentioned befor: I have the same power but a dip in mid rev's. (dyno run)

You didn't say whether there was any impact on the air/fuel ratio on your dyno tests. but it sounds like something is wrong somewhere, perhaps the cams were fitted incorrectly or maybe the ignition advancer has advanced things too far?

I was thinking the same, because befor (a year ago to be exact) he did my dyno-jet stage 2 + k&N and this gave 73 bhp.
Now the engine is running poor at every rev and extreem at low revs. He was thinking about the clearance of the intake valves that is too low. Can be because I forgot to check the clearances after installing the cams...
He told me that If I didn't put he cams right (1 teeth to less or to much for example) this would result in a very bad power-curve and this one is just bad.
