I bought a 2000 CBR 929 RED/BLUE/WHITE. The bike needs a lot of TLC
Work I already did:
- Fairing bolt upgrade
- new oil pan ( old one was cracked near the drain bolt)
- front brake new seals and pads.
but now, I noticed a loud metal knock on the upper engine side, side of the rear brake. Near the air box.
I uploaded a YouTube movie, which clearly lets you hear the noise.
The longer the bike runs, and gets hotter, the less frequent the noise appears.
When cold, every 3 - 8 seconds.
When hot, above 85 degrees celcius its every 15 - 30seconds.
I don't notice the sound when riding, might be because the helmet/street is louder than the knocking sound.
I can not hear the noise when engine is revving 4k+, Might be because exhaust note is very loud.
My main suspects are the CCT, because of the CBR 929 CCT history. But the knocking should be louder/more frequent when rpm's rise, right?
Other suspect is fuel pressure, as the noise appears less frequent when engine temp rises.
I can check the CCT but the position of the CCT on a 929 RR is pretty hard to reach.
Hope you guys/girls can help me.
