Weird Noise. Quick help n e 1?
Okay so I finnaly have switched out my secondaries (RC 750cc) and ive noticed more of this weird sound that sounds sorta like a whining/ bad timing belt sound on a crappy pistonmobile.
This sound once came when the motor warmed up and in the 3k rpm area (right before the secondaries kicked in (which had low impedance injectors rather than high for a lil while)
Now the noise is a little worse and came after I ran the motor up to around 5k-6k rpm at about 6-8psi and then let go of the throttle and got back down to the 3k-4k rpm range (when the noise comes in)
...O ya and since im asking is it okay to have a vacumm leak when it gives you a healthy idle (because when i block it off the rpm's fall and gives me a choppy idle)
Please all help is appreciated!
