im trying not to put any more money in the bike until I decide if I am going to keep it. The bolts I took out of my old engine were all allen. I will see if a hardware store has some longer 6mm.

i've decided if I do sell it, then I will be getting something modern and start looking for a basket case. That way I cant be disappointed for buying a great running bike that has all sorts of problems. probably go for something a bit smaller though. I have been looking for an s90 or one of the tiny cb twins that will fit on my balcony at the apartment. Any recommendations for a smaller one that will have relatively easy to get parts? I know the s90 engines can be swapped for those lifan ones.

yeah thats the plan. I dont expect it to leak too much. only a couple screws are jinky. I did super loctite the exhaust bolts into the engine last time I had the exhaust off. That is the only thing I am nervous about at the moment. The carbs came off fairly easily. Might be taking the girlfriends hair dryer to soften them up in case they dont pop on.

There is a ground cable and the one that goes to the battery, I need to also get into the manual and find out where that goes. Wasnt paying attention in the scramble to get the bike out.
The battery ground cable goes to the top rear bolt on the back of the engine, preferably between the frame and the engine case. From there it is almost a straight shot up to the (-) on the battery.

heres two wires, one comes from the engine and I cant remember where the other one came from.




the one looks like it was held on with a bolt somewhere but I cant figure it out from the wiring diagram. Were almost ready to start it though

That looks like the ground wire that goes from the battery to the rear upper engine mount bolt on the left side of the engine . It should go between the engine and the frame but can also go between the head of the bolt and the frame . Better contact if it goes between frame and engine . One end will have a round loop ( engine end )and the other end ( battery end ) will have a elongated loop . Got my fingers crossed .

So, yesterday I headed up to Austin and Aaron came down to help me work on it. It was mostly the basic little things to button up. The electrical on the bike has had more monkey fingers in it than the lady from King Kong. So that took a little bit of psychic ability.

We had no spark until we hooked back up the Hondaman ignition. The spark is still a bit weak, so it may not be hooked up properly. The only wires going to the points plate are blue, yellow, and a green. I am not sure if the two greens that are stock in the plate need to be taken off as they were on my old engine.   ???

but the bike ran for a few minutes. carb bowl gasket on 3 was all jacked up and mis shapen. I battled that when I first got the bike, but only replaced the 1/2 gaskets. I thought I had lost the 3/4 gaskets but I found them as soon as I got home, right where they should be too. I think I have torn through my apartment several times looking for them assuming I had lost them and not looked in the drawer I put them in...

I still have to get the bike timed and get a new battery. I think spark plug wire too.

I am pretty pessimistic. So I have to say that I was afraid this whole fiasco would be pointless. When it finally turned over I was a bit dazed and confused. It took me about 20 minutes to be relieved. This bike really has taken me through the gauntlet of relational emotions.

I have to head home for a week but I will probably cut that short so that I can finish this up before my trip. I might head up there for a bit tomorrow to throw on these gaskets and see if I can change the oil real quick. thatll just leave the battery and spark plug wire and timing it I think.

Runs alright, that rattle is probably carbs out of synchronisation, set those right and she will probably purrrr.....I gotta love your determination AJ. :D

alright, So... I came back up to hopefully get everything done but now I cant get it to idle. I bought a new battery for it and charged it for about an hour. Took off the Green wires on my points to match my previous points, hondaman ignition system. And put the good gaskets on 3/4.

It'll run for a couple cycles, about a second then die.


I've tried adjusting my idle, but it doesnt seem to be idling long enough for that to matter.

It backfired once pretty loud and feels like its flooding. But I dont really know if thats the case, lack of experience.

Those of you with the hondaman ignition, do the green wires need to be on my points plate or not?

Any ideas? I leave in two days so I am kind of freaking out now...  :-[

Mark has told me that the ground wire that attaches at the points plate MUST be attached at the points plate, if you are indeed referring to the ground wire with a loop on the end.

This sounds like timing/ignition to me. Keep at it. You almost have it whipped.

I will read today about static timing. It ran on sunday, so I feel like I must have done something. The new battery is great though. The whole time I've had the bike I have used a crap battery, so its cool to not worry about killing it after thirty seconds.


The points plate on the previous engine had the two green wires disconnected. So I will be PMing HM, to see what he thinks.

Also, my carb boots are pretty much crap, they should have been replaced last time they were off the bike, but it looks like the PO just electrical taped them to create a better seal. This sucks because that means the carbs need to come off. I am getting fule into the bowls at least, but I am also concerned that the tank has sent some deposits and clogged my idles. Should have put on an inline fuel filter... DOH  :o

Tuning I am no good at unfortunately. Trying though.

I am trying to do the static timing. Here are the pictures of when my ohm meter starts beeping. The one looks all wrong, for the 2/3... going to try it with the voltmeter next and see if its the same results. Ive never done this before.

2 3 points should open when 2 3 is at f. same with 1 4. if its reversed then the cam under the plate is in wrong. also make sure the little fiber washers are in good shape on the points where the condensors bolt up.  if the gap is wrong you wont get spark. Do you have a haynes manual or something like it?
