I am selling my wife,s 03 z-400 and giving her my 05 z-400 and getting a 450, just do not know wich one yet. Anyway I am selling it to my neighbor and need to adjust the valves first, does anyone know the valve specs?

 

the 03/05 specs are 0.10-0.20 intake cold (0.0039-0.0078 mm )
0.20-0.30 exhaust cold (0.0078-0.0118 mm )

 

I think mucky means .1mm to .2mm or (.0039-.0078 inches)

 

Yea 10 to 20 thou and 20 to 30 thou sound very loose. I have only checked the exaust so very and they are about 10 thou. I am hoping the valves are loose and making noise and not the t-chain.

 

exhaust- .008in intake- .006in (with feeler guage)

was said to be the best for all

 

Thanks, that sounds better. I called my local dealer and they would not help me with the specs and said it would take 5-7 days to order the shims.

 

how much do shims cost? cuz all you need is the feeler guage.

 

To adjust the valve you must change the shim under the puck. You can get a set of shims on E-bay for about $70.

 

wow who told you this?

 

I have read about it here on this forum, just search --valve adjustment--. Plus I have it apart in my garage.
