the valves were loose could that have had anything to do with it
please help me

are you getting fuel? spark? it might have jumped time if the timing chain get to loose. bad spark plug? CDI malfunction?blown fuse?

 

i dont know
all i know is i was in a wheelie in third gear and it backfires bout 3 times and dies
then i tryed starting it and the motor wouldnt turn over

 

What you mean valves were loose? Is it a overhead cam?

 

the cliccking in the motor was caused by the loose valves
and i didnt get around to fixing them
could the valves caused any of this or would it be somthing else
and its a new spark plug and the carb was recently cleaned

 

Well if the valves arent seating yes of course (I have been there with mx'ers). I would check the clearences, they will have gone to zero clearence if the seats are shot.

 

You said about the motor not turning over? Is it locked up?

 

well it sounds like it wants to start but it wont
and the motor is not locked up
but my mechanic said i needed to tighten the valves
but he pulled his arm and we didnt get to do it
im just getting opinions on what possibly could have went wrong before we go and take the motor apart and its something simple

 

I persume its an over head cam. If it is over time the valves tighten, not loosen (this is mx'ers anyway) You will have to shim them. But I would say seen as its an 03 I can only persume it has a good few hours on it. A valve job would do no harm. Do you have a manual? Cheack the clearencs, it is very simple to do and it will tell you if you need shimming or not.

 

yep 2003 ltz 400 5 speed
i will reply back when i get around to taking it apart probally sometime next week or so
thank you for helping me
