ok i took my magneto cover off the other day...while it was off i thought today i would check how far off my timing was (it's off 1/8 - 3/16 of an inch on the cam timing)...so i pulled the valve cover off and was turning the engine over by hand and every time i got to the intake stroke (intake cam going down and exhaust was flat) i would hear a click!!! i though "hey maybe that's the ticking noise i've been hearing every since my big bore was put in"....so i kept doing it rolling the fly wheel back and forth and it would keep clicking at the begining of the intake stroke!!! what do you think it is????

also how much free play should be in the cam chain...i can push it down and pull it up about 1/4" each way ...is this normal

please let me know what you think!!!

thanks

 

the clicking is coming from the top of the head by the cam sprocket on the intake cam.....forgot to mention that

 

is any willing to take the valve cover off their pred and try something for me?

 

some one has got to know what this is ....if you need it to be explained better pm me your # and i'll call and try to explain better!!! can't get hold of doug nicholas

 

If you are getting a click when turning over by hand slow, I'd check the rockers(I'm assuming it's set up similar to a raptor, but haven't played with a predator under the valve cover) Sounds like way too much lash. Or maybe a broken valve spring.

 

too much lash??? what's that? yes i am turning over slowly by hand....and when the intake strok begins that's when i hear it! i also hear it when the engine is running too, well i think that is the noise i'm hearing

 

well i talked to doug...he said the click is the decomp on the exhuast cam.....but i need new cam chain and tensioner!!!!! and posibly cams to!!!! valves are ok!!! that sucks....replacing a valve would be cheaper!!

that also explains why my timing keeps jumping a tooth!!!

 

Sorry to hear that, I think I will do some engine work next winter...I just ordered my rath header yesterday. I'm still waiting on the cdi box for the 05.

 

i'll get through it ....i'm glad all this is going down in the winter LOL....stay out of the engine as long as possible just my 2 cents!!!

 

Thats what I was thinking to, I would like to get bigger cams, and maybe a porting job. I want to stay with the stock bore.
