I dont know if yall remember but a while back i metioned a wierd noise. i havent had time to investigate it since then but i finally did today. i was convinced all along it was something to do with the chain. when riding hard offroad you could hear it hitting somewhere, at first i thought it was hitting the metal case gaurd under the countershaft sprocket cover, nope. i took my chaingaurd off to make cleaning easier, turns out it was hitting the top of the front mounting flange. i taped it up with thick tape and tested it out and noise gone! so i would suggest leaving gaurd on or cut flange off. keith

 

What is the front mounting flange? You mean the front mounting flange for the chain guard that sticks up of the swingarm?

 

I lowered the back using Kouba. Ever since, I hear a noise like the chain is rubbing against something plastic ... flutter sound. It make this noise when the rear is compressed. Is this the same noise as the one you're describing?

 

yeah. the foward piece that the chainguard mounting bolt goes into that sticks up.

this noise was more of a clanking metal sound not plastic and was very noticable but it was only when accelerating hard while going over bumps fast or wheelies

 

Most likely you just bent it because i had the same problem that stock chaine gard is really wimpy a tap from a rock and it was bent so you probably just need to replace it with a aftermarket one good luck

 

no nothing bent. i took the chain guard off on purpose to make it easier to clean the chain. and the tab is not bent

 

my chainguard is off ... no noise

 

My chain guard is also off - no noise or hitting on mounting tab.

Was your chain tension right?

Also if you're not running an O-ring chain, you may have a little more side-ways flex in your chain which could result in it hitting that tab?

 

according to kawi specs tension was ok. maybe a tad on the loose side. just barely hitting. can see small mark where was hitting. no big deal fixed now
