What would cause you to not be able to get the timing all the way to the timing mark. I put in a standard pamco. Installed the coil an everything that came with it.When I try to time it I cant get it to go all the way to the timing mark before it goes as far as you can turn the pamco.It will start runs like crap pops threw right exsuat an sometimes backfires threw left carb.Which I have cleaned the carbs.Now im lost an would love some ideals.Riding season here, an here I sit.All also put new brushs in.1977D basily stock besides exhaust now pamco.

1sthough, I had an issue with my chain being stretched. Here's the steps I went through and the help the other members gave me. http://www.xs650.com/threads/getting-started-again-72-xs2.43413/page-3
It the timing was right b4 the pamco you should b able to get it. I don't have a pamco I have an 80 with tci. I think I remember reading about this tho and there might be a way to change where the pamco maxes out. Reach out to Pamco idk why but I feel like it's an easy fix.

Is it too far advanced or too far retarded? Also, try using the other spark plug wire as one of the wires works better than the other.
There is a locating pin in the cam for the advance unit. At TDC, it should point straight up (or down). Here's some info on it .....

So yes, you can check the chain stretch without having to take too much apart. In fact, if you're lucky, you may not have to take anything apart. There is a retention pin for the locating pin pressed into the back of the advance plate. This helps keep the pin from flinging out while the cam spins. It's directly above the locating pin .....
..... and it shows through on the outside .....
Now, like I said, if you're lucky and the slotted nut doesn't cover it, you can check the chain stretch without removing any parts .....

Perhaps your issue is something more simple. If you are trying to retard it, and the PAMCO backing plate won't seem to move any father counterclockwise, it could be that the incoming wrapped wires down at 5:00 are simply binding the mechanism. (They can be a bit stiff when cold and new, despite being a fine gauge). If so, Take a pair of fine needle nose pliers and gently, carefully, assist the incoming wire bundle to come (inside) through the rubber grommet another 1/4 inch or so. I needed to do just this when I installed a PAMCO in my'75 a couple months ago.
You might need to assist the wire bundle in making an appropriate kink upwards such that the wires clear the "rotor" which might have a speck of runout.
For me, otherwise, it was a simple, nice installation. Started up instantly. Love the PAMCO.

As far as I CAN GET IT TO ADVANCE is in between the f mark and the t it will go about half way an the pamco is maxed out an wont turn any further

Sorry to suggest this, but are you turning the plate in the correct direction? If the timing is as retarded as that, you need to turn the plate clockwise. You can also loosen the nut holding the PAMCO rotor and then hold the rotor fully counter clockwise while re tightening the nut to take out the free play. Also, as mentioned above, if you are using the wrong spark plug wire for the timing light, it could be producing an errant signal that would be very retarded because the light will flash at the end of the pulse instead of the start of the pulse.
I will give it a try but that seems like it would retard it more.

Now I'm confused. If you turned the plate counter clockwise the timing would be even more retarded. Clockwise is turning it right, counterclockwise is turning it left. The cam rotates counterclockwise, so if you move the plate counterclockwise, it will take longer for the magnets to trigger the sensor.
yea i dont. thats y im on here looking for help
I'm sorry too. I just can't understand your "texting" type input here. We don't post like that. We post in full, complete punctuated sentences. I'm sorry if I'm coming off as the local punctuation "Nazi", but believe me, you will get more help and answers if you post correctly. But, that begs the question - what is correct? Well, I can't say for sure but I do know it's not what you're doing.
I know, this is a terrible response to an "I need help ...." question. It's the best you'll get with posts like yours. We can help, figure out the problem in most cases, but our response is based on your input. So far your input sucks. It's poorly written and contradictory to what actually happens during the ignition setting process.
I don't usually recommend this because we're here to help owners and save them money but you need to take your bike to a motorcycle shop. It will cost you hundreds of dollars but it's better than no running bike. Better yet, sell it and buy a Honda. I for one don't give a shit if another Honda bites the dust. It does bother me however, if some know-nothing thinks-he's-a-mechanic kills another Yamaha.

OK guys, lets all take a breath and step back. 1sthough it really sounds like your cam chain is stretched. Was the bike running ok before you installed the ignition or did you buy the bike and put the Pamco on before you tried it? You really need to look into the chain and do all the checks described here. I know sometimes it can be frustrating as I went through the same thing but it's all a process of elimination. The timing plate only attaches one way so do the checks, post some pics and you will get this worked out.
