angle ones are prefered. i use straight on all of mine but i have bent the tip just a lil on them so they are easier to work with.

For future reference and reassembly It's MUCH easier if you unbolt the cam gear from the cam before trying to get it all out of the chain. Same for reinstall. Put the cam in first, than bolt the gear to it, then add tension.


Thats how I've always done it on CRF rebuilds anyway.

the crf uni cam design is a lil different than the convetnonal set up. the correct way to do his would have been to leave the cam gear on the cam in the first place. they way they are set up, you pull 2 dowel pins and the cam bearing slide off then you take the chain off and the whole assembly comes out. you cant physically take the gear off that set up with the cam still in the motor. on a uni cam you have to remove the cam gear to get the cam out.

lots of traffic on there-- if you're really trying to get rid of it.

Just turned it over two full crank rotations -- no binding sticking or grinding. THere was one spot where I felt like I was having to use more force to turn it (opening valves maybe?) but I was probably just imaginging it. I tried adjusting the valves last night when my girl was over (needed her to hold the wrench) but things just weren't going as well as I needed them too.

I had a normal wrench (is there such thing as a 'normal wrench'? haha) instead of a box wrench, and I self-bent my feeler gauges and i seemed to have left a little too much space at the end. I'm going to give it a try again - but will likely go pick up a 10mm box wrench and a proper set of gauges.

box wrench is the one to use. open does not work well. did you have the spark plug in when turing it over?

Yeah. Which reminds me. I need the appropriate deep socket so I can pull the old one out. None of my shit fits. Ill pick that up today while i'm out.

I got a 12mm deep but its not big enough. IS there a standard size for spark plugs? I did a quick search through the clymer but didnt see anything pointing me in the right direction.

Maybe a 14mm? I'm guestimating -- the angle that the spark plug sits makes it nearly impossible to see correctly from any vantage point.

Thats the pic I was looking for. I see what you mean now. Never worked on an older bike like this before, thanks for the education.

quick26

the compression stroke was your stiff spot. honda uses a special stamped tool due to the lack of clearance on those heads. the plug is a metric size but you need the honda tool to change it.

no problem.
