4 stroke?

[lilblaster]

my frends 4stroke is makeing a ticking noise and his dads woried about it. he replaced the camshaft and made sure the valves were adjusted right any one know what it could be??

 

[Stryder917]

does he hav an aftermarket pipe? cuz they tap against a piece and make a ticking noise.. thats what my 400ex did... it also could be just a few loose parts...

thats ticking noise is most likely timing chain i say so since somebody play in the head,mayby the chain tensionner is not ajusted,waith a minute you said he change the cam,if he put a aftermarket cam its normal since the lift and duration are longer and higher so dont worried

 

[razrman]

is he running good gas in it, sometimes when you use 87 octane in some engines it causes them to detonate and makes a ticking noise, this is common in most sport quads

 

[lilblaster]

its not a sport quad but could it still be that and he replaced the oil pump 2

 

[randelator]

no its the cam chain ajuster go see the stealership !!!

 

[lilblaster]
