I have 11.1 JE 102 piston with hot cam stage II. the bike has been running great for the past 6 months or so, now, it still runs fine but with a little ticking sound comming from the engine (almost like a hot metal cooling down kindda clicking sound) so I am thinking it's time to readjust the valves. and since I was not the only who installed the cam, I am not sure what's the valve clearence that goes good with my set up.


thanks

 

Dont sound good[img]i/expressions/face-icon-small-smile.gif[/img] could be valves, what did you adjust them to when you had the cam put in? did you machine down the middle valve guide?

 

intake: 0.20mm
exhaust: 0.25mm

clearance for the valves.....if thats what you were looking for.

 

yup, all what I want to know is what's the proper valves clearance for hotcam stage II with JE 11.1/102 piston ?

Ward, the valve clearance u just gave me are for stock cams or stage II cams? they seem to be a bit loose for stage II, but I might be wrong tho.

thanks

 

If the valves are right on, I would check deeper. I thought mine was a tap-it noise, so I was thinking valvetrain, but as I tore deeper, the JE wristpin was broken in half. check out the pics on my page.

hope not!!!

 

Those are correct factory specs from Hot Cam for a stage 2.

 

I would adjust the valves and if that didn't help it will probaly be time to go deeper into the motor. [img]i/expressions/face-icon-small-sad.gif[/img]

 

how much of a ticking are you talking about. Mine has had a ton of valve tapping noise since new. I checked the valve clearence and its right on. I'm told with the highier lift on the cam its creates more noise. I never had my values ground down. I was told this you didnt have to do that on newer bikes just the 01's.

 

That is false info. The head/valves (motor for that matter) never changed year to year. Although I ahve never heard of a Raptor that had to have a machined valve guide with a stage 2 cam.

 

I would check the vavles. But, the heavier vavle springs are probably making the noise.
