    Both cylinders? If so, suspect petcock...if one, probably the carb.

    Right cylinder was running great. Could pull the sparkplug boot of the left and it made no difference. Pulled the right and it stalled immediately.

    Got a used starter and installed it. I think I'll be able to actually RIDE the thing!

    Well yeah ...... for a while ........ until something else .........

    That's generally the way with any old bike, sure some (mythical?) bikes never seem to have a problem, where's the challenge in that? Have fun riding!

    Far too true! I took it out for a short 20 miles today and it ran beautifully. (Well, slight popping on deceleration out of the left cylinder--screw mixture set too lean I would guess.)

    Have to admit, I was riding along waiting for something to go wrong.

    Took it out yesterday and it ran beautifully for about 40 of 45 minutes. Five minutes from home the left cylinder started loading up again.

    Knew immediately that the left float needle was sticking again. Pulled the carbs and installed one given to me by a GR rider in PA. Seems to be running well again. The old needle is permanently out of service.

    Figured out why my choke was sticking and resolved that while I had the carbs off as well.

    I pulled the Superbike bars off the other day. Just hurt to ride it longer than about 25 minutes. Went back to the MX bars I had installed a year ago. Resolved the neck pain and nerve numbness kicked up by the lower bars. I can also see things in my mirrors--an ongoing issue with the narrower bars. The MX bars don't look as classic, but they feel WAY better. That'll do for now.

    So, starter issue resolved, carb flooding issue taken care of, neck pain gone--should be good to go until the neck

    Nice. I've yet to pull the carbs again to find out my loading problem.

    Bummer. Have you determined whether it is one cylinder or both?

    Got mine out for a shakedown ride tonight. I don't think I've had it running better than it did this evening. Makes me nervous. :D

    Bike continues to run well. Figured out an inexpensive way to mount
    The GoPro, so videos to come

    I'm going to send the carbs to one of our club members that supposed to be a wizard at carbs. Dog knows I'm not too good at it.:lol3

    They aren't real complicated and there are some really good walk-throughs on thegsresources.com. A GSR member, basscliff, has bunch of tutorials on his page.

    I've been riding more than wrenching...and I like riding more. :D

    The front brake still seems like it has a long pull, so I will likely have to bleed the lines again. Stops okay and I've never felt that I couldn't stop within an appropriate distance, but I'd like a firmer feel at the beginning.

    Other than that...I'm really happy with how it runs an rides. Longest ride so far has been about 100 miles, but I may get to improve on that before the semester starts in late August. Riding time drops in a major way when that happens.

    I'm not a huge fan of the seat. Not real comfortable by the time I got back from the longer ride, but I did 60 miles yesterday and it was okay.

    I think it is safe to begin thinking about dealing with cosmetic issues, rather than mechanical. It does have a base gasket leak that I'm going to have to take care of, but that will likely be a winter project. Finally got it running and don't want it out of service during ride time.

    Starting to look at similar style bikes to get some ideas about paint options.

    Never thought I'd like a white bike, but this one has caught my eye. [​IMG]

    Has longer pipes on it...I probably won't do that--adds to the work needed to remove the tire--and it has twin discs on it. Might consider that at some point.

    Owner has cut down the seat and removed the passenger grab rail. That could work for me. Nice clean looking bike.

    Spent several hours today tearing the front brake lines and master cylinder off. Spent time bench bleeding the MC and retightened the banjo bolts and connectors.

    Found two crush washers on the inside of the caliper banjo bolt. Obviously an idiot worked on it last.

    Bled the system it seems much better. Less lever pull and more power to stop.

    Had to use that power on a test run as a flock of Canadian Geese decided to launch in front of me. Canada, you are welcome to come get your geese anytime. Hate those things.:D

    Once again, the premature "whoo-hoo" with the brakes. I may have to just tear down to ground zero and start all over. Completely frustrated with it at this point.

    Bike is running well. Rode it to work and back yesterday. About 70 miles. Not a hiccup other than the front brake.

    Newest issue is that the gas gauge has decided not to work properly. Sounds like something is loose inside the tank. I'll let it float until the riding season is over. Plan to paint the tank at that point anyway, so I'll fix it later.

    Hit 13,000 miles on the odometer as I pulled into to work.

    Ebay is your friend. Get a master from a GS500 and be done. You'll need to do something about the front brake wiring and the lever will be silver, but no one has noticed mine yet.:D

    Got any closeup pix of your front MC? I see a couple of different GS500 MC's on Ebay and I'm not sure which style to go for.

    One has the banjo bolt where the GR's is and the other has it coming out the end of the MC.

    Yep, here you go. I am running a steel braided line and had to swivel the banjo, but this setup allows the line to do that. Perhaps your hose is bad?

    Thanks, VTwin,

    I was afraid that that style might put the brake lever too far out from the grip.

    Think my cable is okay--just made a stainless line and installed it in June. Only thing I didn't change out was the rubber diaphragm under the cap on the MC.

    I believe I might have to follow your path with it.

    I think I fixed it! Okay, I know I've said that about a dozen times this summer, but I really think I got it right this time.

    Started in at about 8:00 this a.m. and took the caliper off. Wanted to be sure it wasn't leaking from around the piston. I checked the MC two weeks ago and found nothing wrong there.

    No leaks at the caliper end. Pulled the stainless line off and took another shot at tightening both banjo bolts. One of them was LOOSE! Cranked it down and reassembled the system. Immediately noticed a difference when I started bleeding the brakes. Almost no air bubbles after ten minutes.

    Tons more brake with far less lever pull.

    Almost hesitate to say it, but rode about 15 miles and it never reverted back to the long pull feel.

    I didn't think the line was the issue because it never leaked fluid. Apparently it will pull air, but not leak. :eek1
    Didn't know that.
