Hey guys, Trying to rewire my 76 650C. I've worked on just about everything mechanical on this bike but the wiring is garbage and it's currently not starting (battery is good, fuse is good, no power to key). I figured it was time to rewire anyway so I jumped in. Now I'm a bit stumped... I've...

Gotcha. That was my main wonder. I'll go through the typical non-running symptoms then and update! Thanks!

Sorry for the late reply. I'll check those things today. I'm 98% sure my breather tube is good as I was REALLY careful about that and had it pulled out of the way when I put it in. That one busted seal (at the pushrod) would be enough for me to lose compression and not start correct? I'm going...

What a weird title.... I just finished pulling the engine in my 650 and replacing valve stem seals because I was burning oil on one cylinder. Put it all back together and buttoned up, rode it down the block all proud and BANG! Two loud backfires and DOA. I think it’s the clutch pushrod seal as...

hey guys I have a ‘76 that’s I’m replacing the valve stem seals on as I m losing some oil and have a smoky exhaust on the left side. I was going to replace some of the gaskets (bought from mikes) as well. In disassembly I found some oil pooling in the points(pamco)/advance covers, as well as...

Hey guys, Where the heck do I find the barbs for the '76 carbs? My carbs are close to sync and I'd like to buy a manometer to actually get them perfect. I have '76 carbs with the small screw plugging the vacuum port, but I can't find the dang thing anywhere on the internet. Help?

Hey guys I'm in need of some new carb holders as mine are suffering from years in a barn. I know there has been questions of quality, but I'd like the barbs from the ones on Mikesxs as I have my carbs ALMOST tuned by ear but I can't seem to get them perfectly spot on no matter how thoroughly I...

Is there a way I can test to see if my plug caps are resistor caps? Also, is there a link to how to change timing with the pamco somewhere?

Hey guys So I bought a '76 650C last July and have been riding it 4-5 times a week since (Texas winters!). I've done routine maintenance on it (oil, filters, side cover gaskets), some light mod work and cleaned the carbs a couple times. I've been having this weird issue lately where my left...

Update: I ordered the copper washers from Mike's and put them on all bolts below oil level and my filter bolts, however I still have a leak. The Athena gasket I bought is slightly bigger than the cover and sticks out about 1/16" out of the bottom of the case. I tried wiggling and repositioning...

It’s got some scuffs where it rubbed on the master cylinder and some really minor pitting.

I can upload a better one later tonight. It's in pretty good shape, some minor scuffs and stuff. It's not chrome though, it's black. I believe that was stock on the '76. Here is another really terrible shot from the side just to show the wiring, if that helps.

I considered that, but the forum seems split on using adhesive/sealer so I didn’t risk it this time. I’m going to try adding the copper washers mentioned above to see if that seals it. It’s not pouring out, just a slow steady leak.

Yeah, I used paint remover to eat away at the old gasket and a utility knife with duct tape on it to scrap it off. The surface was pretty dang clean and I double checked for any gouges or high spots before I put it on.

Yeah when i replaced the gasket and bolts I torqued them all to 7ft/lbs, which is why I started this thread. I’m guessing the PO just had them so tight it didn’t leak before, but in torquing it to spec it needs those copper washers to seal all the way up.

This is my first bike actually. I'm kind of a youngster (25) up against you seasoned vets! I checked the threads before I put the cover back on and they looked ok, didn't see any shavings on any of the bolts when I pulled the either.

I'm sorry, stripped the Allen heads. They were on so tight I had to pray them off. I was using a 5mm Allen wrench and socket eventually.

That must be it. It didn't have them on before I opened it up the first time and no leaks, but it looked like it hadn't been removed in 20+ years and was over torqued to hell, I stripped almost all of my bolts trying to get them out and had to buy new ones. Will put those on and see if it...

I had to fish for the tach drive washer on my ‘76 650C so I took the RH cover off. Fished it, out everything back together (save the kickstart), then discovered I tore my old gasket so it started to leak. Looked like the original so I decided it’s time to replace. Chipped off the old gasket...
