No problem, we 750 twin owners have to stick together or the four cylinder owners will take over the world :laugh: :laugh: :laugh:
Judging from this group...they already have :lol: :lol:

This was the majic bullet that finally resulted in a firm brake on my 650.

On the brakes, I recommend bleeding as follows: Put the bike on the centerstand and turn the handlebars to the left so that the right side (the side with the master cylinder) is pointing up. Remove the caliper. Press the piston back into the caliper. I used a C-clamp. Remove the C-clamp. Work the brake lever to push the piston back out. Be careful not to push it completely out. Repeat about three times.

Thanks for the reply and method, bemoore. The CSR does not have a centerstand. I've been using 2 pieces of 2x4 under the side stand just to get it to stand up straight so the master cylinder is horizontal. Are you just saying to push the caliper in then pump it out...w/o bleeding the caliper or putting fluid into the master cylinder? I think I see how this might work, by pushing air bubbles up the break line but just want to be sure.
Thanks

Hey guys, I wanted to let you know about my progress.
The best news is SHE'S ALIVE . I had her out around the neighborhood today. She's running fine right now, except there is an occasional stumble right as I crack the throttle to take off, I'm hoping the sea foam will work through that. I've got her idling around 950 w/the choke closed and starts cold w/several kicks, on full choke. When warm she starts w/1 kick and no choke:) I did several things so I really don't know what fixed her. I put on the Wired George coil mod. I went up to a #50 pilot jet and also found that one of my carb journels was clogged. I think the "Sea Foam" is helping to clean the system and now will get better the more I ride. I still need to balance the carbs and when I get a chance I'll check/adjust the valves. I'm also still getting some cam chain noise, evethough I adjusted the tensioner.
I still have the starter problem. When the bikes cold, something is still slipping and the starter won't crank the engine and I get a chain running on teeth sound. Once she's warmed up the starter kicks her right over. I've got to replace the stator, getting no juice whatsoever, so while I have that cover off I'll see if I can't do something about tightening the chain. It's not that big of a deal as I can always kickstart.
Although I've got the brakes working, they still feel mushy, but driveable. Much better than they had been. I'm going to replace the brakeline w/a braided line. I think I can feel the brakeline "pulsing" when I pump the brake.
Anyway I wanted to thank everyone for all their suggestions and help.
She's a runnin'...ye ha!!!

YAY!....SHE'S ALIVE ....
Sounds like the carbs are out of balance, or the pilot still needs adjustment, or the floats are wrong.there is an occasional stumble right as I crack the throttle to take off....
Hmm. Depending on the sound, might it actually be vavle noise? That would be potentially good, though, since noisy valves are happy valves... to an extent.I'm also still getting some cam chain noise, evethough I adjusted the tensioner.
I don't know. It just sounds like the famous starter clutch failure like all of our twins have.I still have the starter problem....
Ok that's not good. Not likely the line, more likely a off-balance wheel/tire, warped disk, or something like that.I think I can feel the brakeline "pulsing" when I pump the brake. ...

Git a pic of that bike of yours, I'd like to see it. I'll probably be posting some new pics under another thread when I get her all spiffy

I'm pretty sure the floats are good, pilot adjustment and balance are probably the culprets

Could be...I'm going to have someone, who knows more than me, give it a once over when I can get it over to him

Unfortunately I'm sure the chain is comming off the lower sprocket, because I've seen it when I've had the cover off. And I've had the starter rebuilt.

Sorry, a miscommunication. I ment that I've put my hand around the line and I've felt it pulsing when I pump the handle. Not while I'm riding
Thanks
I'm just happy she's running
