berggren7 Posted March 4, 2010 Report Share Posted March 4, 2010 I ride a stock 2008 zx6r. I have noticed that my bike makes a ripping/tearing sound when my engine is running at high rpms (12,000+) It doesnt seem to be affecting the performance, it runs fine. I am pretty sure that it wasnt making this sound durring my first 6000 miles or so. Any suggestions on what this could be? I would greatly appreciate any tips Quote Link to comment Share on other sites More sharing options...

Likwid Posted March 4, 2010 Report Share Posted March 4, 2010 Wounder what your bike would sound like @ 12k let me knowwhen you try it....oh and welcome...I imagine 12,000 rpms sounds silent right after my crankshaft rips out the side of the bike... then the screaming from me flying out of control, and then crying Quote Link to comment Share on other sites More sharing options...

ReconRat Posted March 4, 2010 Report Share Posted March 4, 2010 (edited) chain and exhaust leak are good guesses.When was the last oil change? It might only be engine noise from moving parts.I had a bike modified to do up around 14,000 rpm. It ate one crankshaft, one camshaft, threw off all the piston pin retainers, needed special valve spring set, a racing clutch set, and ruined points sets in about two weeks. Oh, and destroyed the oil quickly, real quickly. And broke a lot of chains. It wasn't worth it.edit: the bike would do 10,500 rpm stock, modified it did 14,500 rpm with fresh points, then dropped...

Disclaimer Posted March 4, 2010 Report Share Posted March 4, 2010 At that RPM, are you sure it's not your ass that's tearing? Quote Link to comment Share on other sites More sharing options...

Moto-Brian Posted March 4, 2010 Report Share Posted March 4, 2010 Wear ear plugs and forget about it... When i go out on the track or ride street w/o them, I think the thing is going to explode into pieces... Quote Link to comment Share on other sites More sharing options...

I rode the Ape around the block once without a helmet and the damn thing sounds like the apocalypse. So many noises, lol. I just keep the earplugs in and ignore it and she keeps delivering the miles.

berggren7 Posted March 4, 2010 Author Report Share Posted March 4, 2010 The sound doesnt bother me, altough it gets louder the higher the rpms. i just dont know if It something serious that i should get fixed to avoid engine damage, i had my last oil change probably 300 miles ago, i take great care of it, but i do ride it hard. It only makes the sound past 12000. 12000 doesnt seem too high considering this thing redlines at 16500 and its designed for these speeds. definalty not the chain, it sounds more like its coming from the engine/exhaust. Any ideas of who can I have check this out in the columbus area that wont charge me a wack-ass price? Thanks for the replies Quote Link to comment Share on other sites More sharing options...

RSVDon Posted March 4, 2010 Report Share Posted March 4, 2010 It's your intake/exhaust noise. It's supposed to sound like that. That's the noise she makes when you're doing it right. Lulz. Or in your case, the noise he makes. Quote Link to comment Share on other sites More sharing options...
