Exclamation Clunking noise? best description

Okay, so this isn't the N to 1st gear issue that I have ran into when researching this issue.

Yes I research before asking but I really don't know how to word this without typing out what happens to see if any of you have ran into this.

Here is the issue..

First off....07 ZX10r...LOVE IT!! had an 03 zx6rr before, then moved to this bike...love it, feels comfortable, enough power...all around great bike.

Ok, so, i'm trying to build confedence with this bike as far as rolling the throttle on in lower gears to feel the power and know what to expect.

I was playing around tonight and noticed in 1st gear, as you all may know who have one, you can chop the throttle then hammer it, and the front end comes up...pretty fun, and i can ride it for a bit :)

Here is my issue, When I chopped the throttle, then directly after I hammered it back on, i heard a kind of clunk or thud as I punched it...

SO I went over the basics to see if any of these were my issue....

Chain tension is about right maybe a .5-1.5 play, the wheel is not bent, I just put new tires on (pilot pures - great tires btw - to each his own obviously) while i had it up on my stand i put it in gear and let the wheel rotate and it looked straight and smooth. SO I'm looking for any other explenation to this noise...anyone else have this?

Thanks!! :)

back lash in the drive train most likely from hammering the throttle on and off .

yes it can be a normal occurance if you 're hamfisted with the throttle while loading and unloading force on the gear box rapidly

i take it, this isn't very good for the bike.

I've only done it once or twice...

I think the thing was, I chopped the throttle to much and the load went to almost nothing which in result caused this noise.

Beating on bearings gears etc. Chopping is not doing your dricetrain anygood. Does it clunk everytime now ?

check you chain tension as said above. I would bet that is it. Also a little cluck is normal.

no it doesn't, it was a once or twice that it happened and i think both times i had it underload then released to much and tried to chop it again...

I wont be doing it anymore that is for sure.

bug man, I think the chain should be tight enough like i was saying there is about 1 inch play...maybe a tad more...

They don't have a rubber bushing in the wheel hub to absorb slack do they?
