Topic: Dialing in a cam

[shizzomynizzo]

I am planning on doing a 650 cam in my 550.
I don't remember reading about having to dial in the cam, but just cam across a post talking about it.

Do I have to dial in the new cam? what exactly does this do? and what happens if I don't?

Im wondering the same thing. I pretty sure you can just throw it in but i wonder if degreeing it would be better.

You can throw it in but dialling a cam with a slotted sprocket means you get the best possible timing at the right time it shoudl happen and that it turn means the best possible power. It's fractions of a percentage but then why wouldn't you want your bike to run as sweet as it possibly could? It's actually really fun to do in a perverse sort of way, you'd be amazed at how far out some cams can be when just thrown in according to the manufacturer's marks.

How do you dial in a cam?  And what kind of tools are required?

youll need a dial indicator and a degree wheelhttp://69.20.53.62/pdf/803.pdf

I've got the dial indicator, just need the degree wheel.  Thanks for the pdf (http://69.20.53.62/pdf/803.pdf).  Good stuff.

And plenty of time....if you're used to it in can be quick I'm sure. I've done about half a dozen now and a SOHC cam takes me about 2 hours to do...

Don't forget the adjustable cam wheel without which, nothing is adjustable you will also need the factory timing figures unless you are going to experiment with your timing.

i got my adjustable sprockets bolt slots cut last night. i'm going to etch the timing marks in it as soon as i can reduce the protractor wheel down to the diameter of the sprocket. ill install it when i take the valve cover off to re-torque the head bolts. i've thought about trying to cut some shallow notches in the sprocket and ones of corresponding sized ones in washers so that all will stay in the position i put them in. gonna have to wait till the daily temps get back above freezing though.

.....and a piston stop to find TDC

Just did a search on here...

google printable degree wheels and have a go at making a carboard one.
