I installed some longer springs on my sons bike,and they were making a kunk noise when they on rebound or unloading.The guy at the parts place said to fix the problem I needed to go with extended fork legs.Well I installed those only to have the same problem.Im sure I ve installed it the way they are supposed to be ,but I cant figure out why they are still making the kunk noise. Anyone have this problem?

 

do you mean when they max out? because i put longer springs in and the bushings were to small so when i maxed them out the fork tube was coming down and hitting the fork guard mounts. i just threw some bigger rubber bushings in and it was fine.

 

you just need to pack the forks w/ grease reall good, mine "kunk" after i hit too many jumps or drops and push most of the grease back out of them.

just pull them most of the way down, grab a handfull of grease and mush it in the springs and all around teh bushings, then put back together and ride

 

Was I supposed to use the bushing out of the stock springs? I guess thats my problem then .I asked the guy at the parts place and he said I didnt need them with the extended fork legs and longer springs.

 

yeah you should defenitly have some sort of bushing in there...doesnt sound like the guy you talked to knows much.

 

yes you need bushings ... if you have upgraded front suspension I would get aftermarket bushings .. like the delrin ...
