I cant believe this 2001 KX100 has a 420 chain on it. Even a TTR125 has a 428 and mine has a 428H on it. Has anyone changed over to a 428 or a 520, if so head me in the right direction with part numbers if possible.
I do know that a lot have people have gone to the 428 chain. I plan to do the same to my wifes bike. The funny thing is that the original owner of the kx100 that i bought for her had switched it over to a 428 chain. The kid that bought it from him had it changed back to a 420! :confused: (we are the third owners)
Probably some one at the kawi shop told him that he had the wrong equipment on the bike. :think:
We just changed out the stock chain and gears on my son's '02 KX85 to 428 gears and a 428 O-ring chain. He races D-17 Hare Scrambles. Talk about lower maintenance! I'd highly recommend same for a KX100.
