i thought bad cct will make rattling sound only around 4k~5k?

 

Please explain

 

bad CCT means the chain is lose inwhich case it will flop around and rattle regardless of RPM. Kawi's are known for CCTs going out, so it doesnt hurt to check it

Wobble is bad any way you look at it and needs to be fixed, if it just started you may have damaged something, have you hit any big potholes lately? Check your rim and tires for any damage and check to make sure they are properly balanced and aligned. if the wobble happens only on brakeing then check your rotors too. Is the wobble constant or only at certain speeds?

 

hmm i just changed the filter and engine oil but theres still sound

 

its wobbling at high speeds like morethan 90~100mph. but before there was no wobble even at 130+

 

so cruizing speeds and transitions is where the wobble is with no load and not depending if it is in 1st or 6? Well 1st gear thru prolly 3rd is under a load at 100mph but what about the others?

The wobble concerns me though. Pull of the wheels, check the static balance, check the tires for condition, and most likely replace the tires and retorque. And as mentioned, check the stem bearings.
