To start... I am certain this question has been asked but for the life of me cannot find the thread. So I am installing MikesXs Part #14-0914, which is the Pamco Ultimate High Output Ignition System. I am installing it on my 77 XS. Everywhere i look and all the youtube videos are all on 80+ year models and I have a 77. I have built this bike pretty much from the manual and with help from my cousin as well. We are not idiots but not professionals either. Could someone out there PLEASE explain to me how to install this system on my year model and dumb it down please. I am a broke college kid and this $200 system set me back a lot of beer money. I dont want to install it incorrectly and be screwed. I am running simplified wiring, (no blinder or any of that jazz) Kick start only, Key to power the bike and a kill switch on the bars too. Mikuni VM36's and a combo reg./rec. if you have a link to a helpful site or another thread I cant seem to find please send it my way. I have looked at the yamahaxs650.com site that everyone is telling me to look at but I cant quite follow. Again I really dont want to screw this system up. The attached pic is my 400 square foot apartment turned Chop shop.   Uploaded with ImageShack.usThanks! |

Joss.
I have stock wire harness,, so not sure if this will help...
Black wire to ground (good ground)
green wire to either side of coil. (no other wires hooked to that)
Red wire, goes to key (kill switch/battery lead) and the other side of the coil (not not matter which color, goes to which side... does not matter what spark plug wire, goes to which spark plug ) Stock wires, this is red and white wire
Print out the 3 page instruction, from Pete's Pamco site.
Set time as directed with timing light, (use a car battery, not the bike battery i find that is easier to do)
I might send you a photo of mine, , if i find one that helps.
I have this GREAT system on both my 75 , and 77 XS.

As Prston said, just follow the instructions on the Pamco Ignition site, can't go wrong. If in doubt pm Pamcopete. He designed and builds the system.

jossh77, There are specific installation sections for each part of the PAMCO ignition system posted on the web site, www.yamahaxs650.com , including recommended methods to install the coils on '71 to '79 models: www.yamahaxs650.com/installing_the_coil.htmThere is a section all about the advance mechanism as well, even though you already have that component on your bike, it wouldn't hurt to review it: www.yamahaxs650.com/installing_the_advance_mechanism.htmIf you have any questions, you can post them here or Email me at: pete@yamahaxs650.comAnd, last but not least, there are tons of members here who can help, like preston, xsleo, 5twins and others. The PAMCO is covered by a one year warranty as well, and that covers installation problems as well so you are not going to lose your hard earned college money. Just be sure that you do not leave the ignition turned on without the engine running! |

Pamco system installed and shes running! After realizing I was kicking for an hour on a dead battery  I charged it up and After 2-3 kicks and playing with the idle she fired up and ran great. The only issue I'm having now is the bike wont break 60-65 mph. It doesn't sound like Im red lining or topping out she just seems to decided to stop going faster at 60. Few Ideas- 1: Float level, not enough fuel at higher speed 2: Spark 3: I have no idea. Im running 36mm VM Mikuni carbs and adjusting the float level is an easy first step to try. After that I can run the bike up to 60mph and kill it, pull over and check the plugs and seee what they look like. Other than trying those two things I'm not really sure what it could be. We'll I also know it could be the jetting. Im running the stock jetting that 650motorcycles.com sends. (not sure exactly what jets they use for "pre-jetted and ready to go") SO my question is how do i adjust the float level in the VM's? |

joshh77,
Well, take a look at these items as well:
1. Low battery / charging system. A low battery will produce a low ignition voltage at the plugs which is most evident at higher RPM's.
2. Timing. Did you use a timing light to set the timing?
3. Stuck or no advance. When checking the timing with the timing light, did you check for maximum advance at 3,000 RPM.
4. Binding advance rod. Check out this video:
5. Fouled plugs. Did you install new plugs? Check them after you got it running?
6. Plug wire not making contact in the coil. Measure the resistance from plug cap to plug cap to ensure that both plug wires are making contact in the coil.
7. Brakes dragging.
8. Speedo out of calibration. You are actually going faster than 60 MPH! Use your GPS to check the speedo.
9. Tire pressure. Pump up to 32 PSI for high speed.
10. Drive chain too tight. That will rob you of power to the wheels.
11. Enricher plunger stuck partially on.
12. Enricher (choke) left on or partially on.
13. Weak or loose advance springs. Weak or loose advance springs cause the advance to use up some of the available movement because you have to essentially retard the advance to get it on the idle advance mark, so there is less movement available at higher RPM's.
14. Timing chain needs adjustment.
15. Cheap or bad gas.
16. Low octane gas.
17. Water in the gas.
18. Partially blocked pet cock or fuel filter.
19. Paper filter that has low flow when the tank is not full.
20. Try a run with a full tank of high octane, fresh, expensive gas.
21. Blocked fuel cap vent.
22. Incorrect sprockets. What RPM are you getting at 60 MPH.
23. Rear tire rubbing on brake rod or swing arm.
24. High wind resistance. Are you a large person?
25. Throttle cable not fully opening the throttles.
26. Blockage in the muffler(s)
27. Dirty or blocked air filters
28. High altitude
29. Very hot air, like 95+F
30. Very cold air, like 32F
31. Low oil
32. Really dirty oil
33. Gas in the oil

Well thats a lot to check. ha ha
I did not use a timing light because I didn't/don't have access to one. I also recently installed a new ATU assembly. Looks like tomorrow I've got a lot to check. As always thanks for the help!

having worked on this bike- these are the things i would check first Josh.
9. Tire pressure. Pump up to 32 PSI for high speed.
10. Drive chain too tight. That will rob you of power to the wheels.
18. Partially blocked pet cock or fuel filter.
19. Paper filter that has low flow when the tank is not full.
25. Throttle cable not fully opening the throttles.
26. Blockage in the muffler(s)
27. Dirty or blocked air filters

In my Pamco experaince ..
first..
The timing must be set,
it is very easy to do (and simple), BUT, you must have a timing light.
The Pamco Ign., is very sensitive, so it must be right.
Then move on, to the above items. (if and as needed)
