Title: z400 3rd gear chatter, trans problems Post by: kfx400rob on April 04, 2009, 11:11:12 AM recently my bike has started making a hard consistent clacking/chattering noise whenever its in 3rd gear, the harder i am on the throttle the louder it gets. it shifts easy and it seems to still hold the power alright though, just makes a bunch of noise. every other gear works flawlessly. the way i ride, 3rd is definitely the one i use the most. i never power shift, ever. does anybody know what needs to be replaced or what the common failure/ wear points are on these things? the bike is an 06.

Title: Re: z400 3rd gear chatter, trans problems Post by: kfx400rob on April 07, 2009, 10:49:12 AM i thought about that, but that wouldn't explain why it only does it in one gear.

sounds like you have a few missing teeth on the 3rd drive gear Title: Re: z400 3rd gear chatter, trans problems Post by: superdooty on April 07, 2009, 06:03:39 PM i have a bottom end for sale thatll fix it.
Title: Re: z400 3rd gear chatter, trans problems Post by: kfx400rob on April 07, 2009, 10:42:06 PM eh, maybe its time for a new motor if i ever get the money... i doubt dumping more time and money into this thing will be worth it, a big bore 2 stroke would be nice.
Title: Re: z400 3rd gear chatter, trans problems Post by: lugnuts on April 08, 2009, 01:09:56 PM its not that much to fix it no need for a new engine I can repair that one cheeper then a replacement engine will cost. and you will know what you got if you get a used engine you never know how good it is or if its good at all till you buy it and put it in and if its no good then you just wasted your money
