Blaaster is right.I have also had a few things brought tome to fix some 1 elses screw up

 

[Herpderplol]

fix to flip.

I plan to do that once i move... maybe

 

[mud runner]

I am anyways very wary when I get something given to me to fix, if the owner says it just broke.

What did they do wrong to make it break, what did they force, what did they do wrong.

What else have they done that caused the breakage, I always look a lot deeper into the problem so that when I replace the broken part, I do not get a nasty surprise.

I know the person that broke it and he knows a lot about working on bikes and knows a whol lot more than I do about rebuilding a 4 stroke im pretty sure he dropped the cam and broke the grar

 

[mud runner]

I sined up to a z400 fourm and theres a guy fairly close to me he said he would help me time it and look it over for me so im gonna see if I can take it over there this weekend and get him to look it over and re shim the valves

 

[harley1-5]

4 strokes aren't hard to fix

 

[mud runner]

4 strokes aren't hard to fix

well iv never worked on one befor and I want him to show me how to work on them

 

[harley1-5]

to seek knowledge is good.You seem pretty sharp I think you will pick it up easy

iv had people tell me that its easy but iv just don't know how to work on them

 

[Blaaster]

It is mainly common sense working on any engine, understanding what the components do.

Take notice of how you take it apart, replace the parts adhering to tensions specified.

Every moving part must be lubricated prior to assembly.

If you are unfamiliar with the engine a manual is a must!

Valves can be tricky tho, must have a manual

 

[mud runner]

ok just got back and I need one intake valve so I bought a stock one on ebay and I need a wheel bearing and a tie rod end

 

[bansheedave]

make sure to lap in the new valve when you get it otherwise it will never seat correctly and leak. the other two issues are easy. also, if your pulling the heat to replace the valve, replace all the valve seals and lap all the valves. that will tighten up the top end and you lessen the chances of oil burn.

 

[Blaaster]

Was the intake valve damaged, or not supplied with the engine, if damaged, go looking why it was damaged.

 

[mud runner]

the valve has gotten dirt in it and worn it down and we couldent get the smallest feeler gauge we had in between the cam and the valve cap he told me he had she same problem with his and the valve stays open a lil all of the time

 

[Larry's Shee]

That would be the last place dirt would "stop" lol. Velocities are highest there of any point of the intake or exhaust tracts. Maybe carbon. Better hope the seats aren't worn out.
You should consider doing a complete valve job while it's apart.

os the z400s the valves ate softer than the seats and they have a problem with them doing this

 

[Blaaster]

Poor adjustment of inlet valves is a major cause of valve and seat wear,
