I have a buddies z 400 in the garage for a valve service(after 2 years, never done) and it is making an incredible amount of noise, the shop where I got the shims told me it's probably the cam chain after 2 years of very hard riding, how hard is it to put in a new chain?

 

isn't there a chain tensioner for those? the chain requires a little side case work.

 

????

 

there is a tensioner that keeps the chain tight those sometimes go bad.

 

well I got the new cam chain in with no problems,but I need to know where the cams should be positioned at TDC, there are a 1,2,3 on the cam gears, what should be pointing up,please help???[img]i/expressions/face-icon-small-confused.gif[/img]

 

Just got done having mine done. [img]i/expressions/face-icon-small-mad.gif[/img] got charged for 5 hours. And after all that, i ran a compresion test and came up 120lb when it should be 140lb. So that means i have a blown compresion ring. theres another 5 hours

 

5 hrs for cams seems high if you have ever done them, i think i can do the ds in 2 maybe 3 hours and i'm not a shop. but they are rather easy to work on.

 

yeah, 3 hours is what it took for the cams. But for the cam chain it took 5 hours. Does that sound right?
