Hey all, I really need some help here. Can someone take a look at the below photo and tell me if this is the correct timing alignment marks for the rotor & stator at top dead center for 76 CR125 Elsinore? The Clymers manual is not really helpful so I thought I would ask. I Installed a Mototek CD125 and the bike ran pretty good, but I felt it was not pulling beyond the stock limiter as it should so I advance the timing per the Mototek instructions (1/4" to the right) and now the bike only want's run when the choke is on? I have moved the stator back and forth and the bike just seems to be running lean yet the blue smoke tells me it rich. I shot some WD40 all over the motor to ensure I don't have any leaks, I just don't understand why it won't run without the choke while it appears to be rich? I set the timing back to the photo below and it still wants to bog out without the choke? Help!
Float level set correctly?
Fresh fuel mix?
Has the bike set with old fuel mix in it?
Have you ohm checked the coil?

Set the timing with a dial indicator through the spark plug hole.
Lastly, I don't care if the Mototek is NOS, trick as shit and cost a small fortune.....it is still 40 years old. PVL, just saying. Eliminates ignition issues from the equation altogether. I can get you a good deal on one in either analog or digital for the old girl.
Newmann is right about the new electronic ignitions. I would take a PVL over a Mototek any day if I was going to race it.
The Shop
I use a battery powered timing light. No matter what you line up or measure, a good timing light can save you a lot of head aches. Took me years to figure that out. Plus is a quicker and more reliable way to check for spark. (Famed YZ 250A not firing under compression, worked fine in the traditional ground the plug and kick).
I have been wanting to install a Mototek, but now I am thinking my procrastinating is finally paying dividends!!!
Good luck
Thanks!
