so i pulled my valve cover off and pulled the cams out of my 95 gsr head and noticed the journals had a few fairly small dug in grooves. only on the very outside tho, how much should i be stressing over this... ive never come into contact with this sort of problem. any input would be appreciated. thanks

 

up

 

anyone???

 

Thats not a good thing id take it to a machine shop to have them check it out

 

can it be fixed with some 2000 grit sand papeR?

 

sand paper????wtf?

i wouldnt even think about doing that...you'll either put more/deeper scratches in that journal, and/or, give the journal a deeper clearance than all of the other ones

dont do it!

 

Yeah I did that to mine with 1500 grit paper. Then had it micro polished for free. As long as you dont take off too much metal your good.

 

so its on the outside? you got rocks in your head flying around lol.. i think it happens im not sure why!

 

You might want to replace your Intake & Exhaust rocker orfices's.
I actualy purchased a damaged Pr3 head that had this sort of wear on it (or in my case bad scoaring) around the journals nearest to the camgears.



I had the head repaired by rewelding the wear then alignboring the journals back to spec. After inspecting the head I wanted to see how the previous owner managed to have oil starvation on just those particular journals. I could'nt see any sign of why until I removed the orfices's and noticed just how brittle and worn their o-rings were, which helps to keep those journals lubed I'm guessing.

I replaced both orfices's then let the motor run for 20min on my initial startup. I took the cams out again to re-inspect for any signs of wear, everything look good.

I have well over 1000K on the motor now, no problems.
