Parts list for 78 GS550 upgrade?

[OldVet66]

I used single connectors on my CompuFire. I found these connectors, the dealer is reputable and shipping from Japan doesn't take nearly as long as you might think. You will need a Weatherpack crimping tool, but that will also work for a lot of vintage connectors: http://www.easternbeaver.com/Main/El...onnectors.html

Awesome! Those will definitely do the trick

Just make sure of the power wiring for the SH-775 before you assemble the plug. The other three stator wires can go in any order.

[Hdale85]

So the one connector just goes to the battery/fuse block, then the other connector is the 3 wires for the stator?

Also does it matter how good a starter solenoid is? I imagine I still need one of those and I believe the one on the bike is bad.

Something like this maybe? http://www.ebay.com/itm/Starter-Sole...b6793d&vxp=mtr

Why not just hard wire them permanently in place? Why would you ever need to disconnect it if it is a reliable system?

Seems like it would be much more reliable without any connectors in the system.

[Hdale85]

Are you talking about the R/R? I'd mainly want the connects so it's nice and water tight and clean looking I guess?

D'ecosse posted a pic of a Triumph part that has the proper connector for the SH-775 regulator. Much better than individual connectors. Just clip off the non-regulator side connectors and use your own for your harness.

As far as the 650 head swap, I'm in the process of doing one currently. You will need the entire top end assembly off a 650. You will also need to do some minor grinding of the lower cases for the larger cylinder skirts to fit into the 550 holes. You will need to create your own cylinder base gasket or order one that is .031 or .032" thick to get the proper squish clearance of .035-.040. Lastly, if you want a torquey engine then use the 650 cams on the 550 sprockets. If you want a high revving engine, use the 550 cams.

Good luck!

Hmm ok, so seems some people were planning to fill the plugs with high quality RTV of some sort that won't crack. I can do something like that and feel relatively good about it.

I've moved mine on a couple of occasions. Mostly because of disassembly of other items. The Triumph part is cheap, fits, allows for removal, and is water tight. What more can you ask for. I would never assume you won't move something...

Only if it's electrical silicon. The other types will turn all the connections green and advance corrosion.

I didn't really see the part you are referring to in that thread? They are just talking about the R/R is also from a couple other models Can Am and such.

That's what wire cutters are for.

Sorry. It's post #81 in the thread. Part no T2500676. I bought mine from bike bandit for 9.95 along with some other parts.

[Hdale85]

Ok, missed that part lol.

[Hdale85]

Ok, for 10 bucks that's not bad I think I'll go for it. So the list is somewhat complete I think? What's the word on the solenoid? I found a ricks part for like 35 bucks? Anything else in there you think we might need? I'm going to buy some wire and a new fuse block as well and when we swap this all over to the new frame it'll get the full heatshrink treatment and tech flex and so on.
