So I am new to the CBR community having just bought my first 2000 CBR 929. I owed a 94 ZX7 prior but didn't have it long. After getting my new CBR home I started to notice a few things I wish I had notice while test driving the bike before I paid 4 grand for it.
The first and scariest to me is a slight intermittent knock at low RPM's. The knock only happens from 1,000 Rpm's to 4,000. I do see the RPM gauge bounce a bit when the knock occurs. It happens very spurratically and is never predictable and goes away with any rpm's over 4,000, constant or just revving.
The second is a low idle... starts up everytime with ease but have to keep it running sometimes. It will occasionally flame out the tailpipe...mis-firing i suspect.
Third, FI indicator on and MIL light flashing 2 blinks.
The last thing is that the headlight, backlights on digital gauge and blinkers stopped working...
The knock scares me, the rest I know can be fixed. All these problems seem to be at idle.
Does anyone know what this knock may be... could all my problems be related? Ive worked on cars all my life but never bikes so I have no idea what noises are normal and what noises I should be concerned with.
The bike rips down the road and all the prblems seem to go away, but all the problems occur at idle.
DID I GET TAKEN FOR A CHUMP WITH A JUNK ?????
