How to set Honda CBR 150 timing
Make sure the motor is on TDC compession stroke when you take it apart.
I'm skipping the tear down because if you want to adjust your timing, im assuming that you already
have it apart.
On TDC place the cam in the head so that both valves are closed.
There should be marks on the cam gear.(cam gear is attached to the cam)
Those marks should be parellel with the head.
While holding the cam in its slot in the head, carefully put the timing chain over the cam gear. You make have to pick the back of the cam up so the front leans forward enough to allow the timing chain to go on.
Once timing chain is on, double check that the motor is still at TDC and that the cam gear marks are parellel; with the head. if not you may have to go one tooth either way to get parellel.
If Motor is still on TDC and your timing marks are good, then your done.
Put the valve rockers back on and the timing chain tensioner, adjust your valve clearance.
With then spark plug out, turn the motor over by hand and watch the valves open and close, if anything is in a bind or if feels tight then your 180 degrees out which means you had you cam in upside down. Turn the cam over 180 degrees and your good to go.
The rotor is keyed so the only way that could go out of time would be if the keyway is sheared, hence the rotor would move retarded or advanced hence back fire out exhaust or intake.
If rotor keyway is sheared, you'll need a puller to pull off the rotor and replace the keyway.
It only goes on one way. On The Keyway.
If your CDI isn't working it will have to be replaced.
If your signal generators isn't working it will have to be replaced.
