cam timing again ( help please chuck?)
cam timing again ( help please chuck?)
Ok, I understand the principle of timing the cams but how on earth do you manage to get a measurement for full lift. It just seems there is no room to get a DTI in there to check valve lift?<br><br>Thanks.<br>mark <p></p><i></i>
cam timing
Whats a DTI?<br><br>I thought you could perhaps measure the diameter of the cam around its narrowest point (its base circle??)and subtract that from the cam "diameter" between the tip of the lobe and the circular part ? This would surely give the amount of lift generated by the lobe?<br><br>So if you put new cams in with higher lift you'd be able to measure the extra lift ?<br><br>someone tell me if im miles off please!<br><!--EZCODE EMOTICON START :rolleyes --><img src=http://www.ezboard.com/images/emoticons/eyes.gif ALT=":rolleyes"><!--EZCODE EMOTICON END--> <p></p><i></i>

Dial Test Indicator<!--EZCODE EMOTICON START :D --><img src=http://www.ezboard.com/images/emoticons/happy.gif ALT=":D"><!--EZCODE EMOTICON END--> <br><br>To measure full lift at a specific crank angle you need to measure the movement of the valve itself and compare to a degree wheel mounted on the end of the crank.<br>These engines are sooo damn fidley to work on and there does not seem to be much room to get the dial test indicator to do the measurment.<br><br>???????<br><br>mark <p></p><i></i>

No, I hadn't thought of that one. Bloody good idea if they screw straight in to DTI. Thanks mate when I get the engine out I'll give that a go, I spent all winter pissing about building up a new engine for my car and now the good weather is here I start thinking about stripping my bike down <!--EZCODE EMOTICON START :o --><img src=http://www.ezboard.com/images/emoticons/embarassed.gif ALT=":o"><!--EZCODE EMOTICON END--> <br><br>Spot the dumb ass<br><br>Mark <p></p><i></i>
