Idle concerns - ZR-1 Net Registry Forums

With the cams reset after full porting will there be a lope in idle? The RPM is about 900. The second issue is when I get on it there seems to be little difference with key on or off, RC injectors installed 2 years ago. I am debating wether to pull the plenum off and check the secondary advance. I put a vacuum gage on with engine running and it holds about 23 hg. SW headers also. Any thoughts.
