So yamaha here in Winnipeg just told me that cam seal is no longer made (79 xs400) so they can't order. Any tips besides eBay lol?

I finally found this vidoe on how ti static time a elecetronic ignition. Put together the same wiring with scrap.

Followed this and it all worked out!

Free wires.... nor red!

Same as point. Just clip the clip to the the coil, is how it was explained to me. It fired up fine before. When I took it out to clean the mechinal advancer. Hasn' fired up since and now has week spark one side and no spark on the other

1978" xs400F I am trying to static time my PAMCO. I have one clip for the timing light on the yellow wire at the coil, the other grounded to the engine. The light stays on regardless, doesn't dim or flicker in any position. Mechanical advancer is super clean and good.

So I am back to static timing. A friend explained to me how to do it with the PAMCO. That said I have used both a test light and a multimeter and the light/current does not go out at all. Checked that the coils are connected correctly to the ignition. Light goes out when the bike is turned...

Checked my coils and they are good. And no spark.... So plugs perhaps? Thoughts?

Did all that yesterday, minus the air mix being 3. Plan is for new plugs tomorrow and see what happens!

Pulled the plugs (one at a time) to see if I am getting a spark. No on the right, intermittently on the left!:cussing:

Cleaned the advancer, and now it won't start. Time to take a few days off from the bike and find a truck to take it to someone! Done Son! I'll admit I'm well beyond my abilities at this point!

I have a flux core welder as well. Splatter is going to happen no matter what. But like the guys are saying, Prep! I have a wire wheel on a grinder and a sanding disk on a second grinder. Make a pass, wire wheel, sand if require and another pass. I made an electronics box for my 650. I started...

Simple way to drain the carbs would be the brass nut on the bottom of the bowl on the carbs. I would take the carbs off for this as it will get messy. Takes 10 min to get the carbs off (ish)

Ok. What your talking about is not static timing. Static (engine not running). It's a timing is a light bulb and 2 wires with allgator clips. I'm picking up with what your saying. I'll strip and clean my mechanical advancer before hand.

First of. Thanks for the help. When I cleaned the carbs today, I gave those diaphragms a close inspection and they are intact. I was under the impression that; You static time, then sync the carbs, and THEN time with a gun. This is my ignition I have. http://xs400ignition.com I have a timing...

http://www.xs400.com/threads/over-raving-vacuum-leak.17015/#post-172179 I'm dealing with some shit problems with my carbs. Over revving, dies when gives gas, won't idle without full choke. Details are in the link If someone can please help, it be apprecated!

After some digging, I found that the gasket was not placed correctly, that was fixed. Carbs were cleaned, bench synced. Put back in the H pipe with the shit Uni Pods. The bike will now only run on full choke. When I try to put in in half way and give it gas it dies. Also, it is still over...

So I decided to start from the begining. While taking apart the carbs, I noticed (I think) the gasket may not be fitting correctly. You can see me pointing to the same hole in the carb body with and without the gasket. Could this be in some way causing an issue (not the source)? I tired to...

You, and a number of other have mentioned plugs. I've done the valves and timing. I read you don' time with a gun until your done tuning your carbs, is this correct? I'm going to re-install the H pipe with these shit uni pods! Pull the plugs and clean them (So I can pull them later And know if...
