    You’re just going to have to keep riding it! My buddy wouldn’t sell me his R1100S so I put the cash on my credit cards.

    I agree that there is no way that I would handle the shipping for the buyer.
    In all the cases where I sold bikes on Cycle Trader, the buyer showed up in person.
    With that said, I am amazed that in three of the cases, the buyer never even asked to test ride the bike before purchase.

    I'm so stoked... tank is painted and mounted so I decided to dump in what gas I had in the garage and try it. I literally fired right up. Idle was way high (no tach) but I was able to calm it down once I located the knob under the carb to adjust it by ear. I had fired the bike before but the idle was erratic for some reason. Now it seemed perfect. Could not resist throwing on the gear and taking it in the cul de sac and up and down the street. It felt great! Outside pics as soon as I get the side covers done. My final to do list looks like this before I can really test it out:

    Paint side covers (underway)
    Wire up relocated rear signal lights and new tail light
    Mount plate and obtain sticker
    Change oil
    Re-check torque on all key bolts and fasteners

    I wonder what Sheila slipped into the gas can.

    Seriously, congratulations on a successful overhaul!
    I was the first person in line when they decided to replace carburetors with fuel injection.
    Now we need to see what kind of paint job was applied.

    If this keeps up, you might have to quit your day job!

    Final product. May get a decal made for the side covers. This bike runs very well. Very pleased with my carb re-build.

    Thanks Keith, lets get a ride in together this season, I haven't been too good at that lately.

    Very nicely done!
    What's the pipe header wrap all about?
    Definitely a fair weather bike. Lack of fairing and shield plus the minimalist fenders would guarantee a pretty good soaking in a downpour.
    Although it might hurt the retro appearance, an aftermarket windscreen might be a practical addition - I never learned to LIKE the taste of bugs!

    My first two motorcycles were unfaired, a ‘72 Kawasaki Enduro, and a ‘74 Honda CB450, as I was riding with a buddy on a beautiful summer day in 1975, he started waving frantically and pulled to the side of the road.
    Turns out he had swallowed a bumblebee. It buzzed all the way down his throat.
    Every bike I have owned since has had a windscreen.
    I guess the experience left an impression on me... :(

    The cheap pipe wrap covers the corroding headers. I'm pretty much a fair weather rider. It's not my daily driver and not intended to be practical.

    Yeah it was fair weather when you were in CF last summer:p

    Wow, that silver really looks awesome on the bike, classy looking. I'm actually considering silver for my CB as well.

    Thanks, I saw this photo below... just look at how the blue red and black contrasts nicely with silver. An idea for a future graphic maybe.

    I think that graphic might look too “busy” on that Honda.
    I think your paint choice compliments the bike’s lines well.
    Just my $.02 worth... :rolleyes:

    Adjusted the clutch cable... the clutch was engaging at the far end of the travel and I realized it was not fully engaging as demonstrated on the highway at high rpms shifting up 4th to 5th. Works perfect now.

    Checked and adjusted the valves yesterday. Seemed pretty straight forward... line up the "T" with the mark by turning the engine counterclockwise. Pull off the valve cover to expose an exhaust valve and 2 intake valves per cylinder. Exhaust valves were pretty much on, intake required loosening. Buttoned it up and started it to adjust cam chain tension and the bike sounds noisier than before but maybe it's my imagination. Did I do anything wrong? Followed the factory service manual.

    Also need some new exhaust gasket for the right hand header into the collector. It's leaking there and making the bike overly loud.

    Screw type adjustment for the valves? Be sure you read the standard vs metric specs and used the correct feeler gauges accordingly. This happened to someone I know, and of course made his valves much more noisy.

    Yes screw type, everything is in metric. The pistons should be at TDC... is there any other way to tell once you line up the marks other than the rockers being slightly loose?

    With this parallel twin... do both pistons move up and down in the same fashion or is one at the bottom of it's stroke while the other is at the top? I suspect not, otherwise the manual would have indicated to do something different depending on which side of the engine I was working on.

    There is TDC on the compression and exhaust stroke. Best to ask herrdeacon, he would be the expert on this.
