Got TDC using my degree wheel, using the method lobe center angle to time cams and checking i/2 a dozen times iam coming up with 106 on the intake, megacycle specs 101 intake, 104.5 on the exhaust, what adjustment do i make to get to megacycle specs, triumph 500 motor, thanks guys!
Remove the camwheel from the intake cam. Without moving the cam, rotate the camwheel 120 degrees clockwise to the next keyway. Fit the camwheel back on. That should advance the timing 4.8 degrees. The cam will actually move slightly when you re-fit the camwheel, but barely perceptible.
Then you'll need a new timing mark on that camwheel, 17 teeth away from the original mark.
You can only change the timing in 4.8 degree increments, unless you start using a selection of different camwheels. If it's advanced 3 degrees, it will still run fine. You could even be happier with it.
4.8 degrees = 1/3 of a tooth 14.4 degrees = a full tooth
Here's something I wrote on another forum. That should give you an idea.(about 2/3 way down the page) You can measure at the top of the pushrod, with a dial gauge. Just take the measurement at the same lift on both the opening and closing ramp. Cam Timing Check
After spending more time on the intake cam utilizing all 3 key ways the numbers i have 98.5, 102.0, 105.0 ran these key ways a couple different times, do these numbers alarm anyone? Plan on trying all 3 key ways during the week to make sure iam getting consistant numbers before moving on to exhaust cam! Thanks for your input guys!
