Okay...


Honestly.. Why the f*ck was I worried/scared to do them?    ??? ??? ???

One of the easiest things I've done.


just wondering, does anyone have any idea without buying one, an easy way to make a tappet tool? (w/ the little square hole)

I ended up using a small crecent wrench worked good, but it'd have been easier w/ the real tool.

total time was about 1-1.5 hours. :clap:



<edit> I put them right in the middle of the specs they give in the manual. Found my intake was bit loose, the exhaust was a bit loose as well, but was REAL close.

I got rid of my valve chatter as well!!!!




I remember reading, valves have a tendancy to tighten over time? why that vs' loosening?

I was a bit aprehensive about doing it the first time, but holly shit its easy. I am use to cam on bucket design. I could not believe it!


You can take a wood deck screw that has a square head and clamp on some vice grips. I didnt have the tool and no one around me had one. I wanted to get it done before we left for Little Sahara.
Just a little 81hp trail bike.

You did set the tolerances to your new cam correct, not the stock ???

Are the bolded ones what I'd be putting them to?

If so I'm literally DEAD NUTS ON. Stock they give you a range to be inbetween, I just shot for the middle and called it a day.

Randy, I don't trust that website's crap.  Half there info was for a CRF450.  :mad:

You should have got a card with the cam with the specs, check it.  Maybe call Steve, or kenneth to see if the got one around to read the number off.

Valve adjustment is easy, as long as you have the right tools. It's not too tough. I just don't like removing plastics.

When I go see the rappy Thursday I'll see if I can find the spec sheet, otherwise I gotta call Bo. He said he was going to send me a sheet with the clearances.

Yeah, HC stg 2 is  .10mm intake and  .18mm exhaust.  You should be good to hook! 
I got a '06 with some KDS Racing bells and whistles  :grin_nod:

How long does it take?  I wouldn't mind doing it at the rally if it doesn't take long.

That'd be the only thing, it doesn't take LONG.. You have to take off the front plastics/gas tank has to come off as well. once that's all off. maybe 15 mins.
