I bought a used 94 dyna convert. EVO. after reading on this forum about the INA cam bearing failure I decided to pull the cam and change out the bearing. while doing this I notice that the ignition module was upgraded to a dyna 2000 HD1. I downloaded the instructions from dynatech websight. in the instructions was told to stactic time the module by finding tdc on compression stroke. ( pull plug put line on flywheel in middle of plug hole) and turning sensor plate clockwise till led light turns off. the problem is that the sensor plate will not rotate far enough to turn light off on the module with lock down bolts install. the sensor was in the up position when I took off. I believe i can make this work if i rotate the sensor to the bottom side. Is this the way the cam sensor should have been install? any ideal or help would be appricated

 

Have you double checked to see if you are on compression stroke or 180 degrees out??

If you have it at the TDC mark on the flywheel (looking thru the timing plug hole) and it doesn't want to time, turn the engine 1 full revolution till the mark comes in again, then it'll time correctly.

 

I don't think I understand this..why would it matter to rotate a full revolution? I am just trying to figure out engine timing too...I thought that by finding the TDC mark, you are just trying to identify what it looks like...but the actual triggering is done with the spark and timing light, right? So if you have the timing mark centered in the hole and try to start the bike, it might not start on the first try. But you do not need to recenter it in the whole if it does not start, right? I would think you could be off by a revolution if you are triggering on the wrong cylinder...doesn't that make more sense? Or am I misunderstanding? I am new with this so I am wondering if my logic is faulty.

 

if you static timing,true,if your using a light with the motor running it dosnt matter

Ok, I understand...thanks.

 

thanks everyone. I got the engine timmed and runnin fine. It was 180 degrees out. My bad.

 

We knew with a lil hint you would figure it out!

 

With an aftermarket nose cone contained ignition module that is capable of single fire operation, (HI-4, Dyna 2ki, etc) there are two pickups on the timing sensor that reads off the trigger which is mounted to the camshaft. The camshaft turns at half the speed of the flywheel. Therefore, if the number 1 cylinder is on TDC of the exhaust stroke, the flywheel will read TDC on the flywheel mark, but the camshaft will be 180 degrees off of firing position for #1. That's why the flywheel needed to be rotated 360 degrees to rotate the cam 180 degrees to the firing position.

This only applies to modules that have a trigger indicator light for static timing. Using a light, it blinks when the coil fires and none of this is relevant...
