  • 1914 Harley 10F or 10E (not sure yet) need help to get started 30+ years of sitting

    Hello all! I've come to some of the motorcycle shows in my local area and finally decided it was time to join the AMCA. You guys seem like a great group, and with most of what I own being in the 70's I can't see any reason not to join!!

    I've got a friend who got a bike from his grandfather. The crazy thing, is that it's one HELL of a bike! It's a 1914 10F or 10E. I've been just researching it for the past couple of weeks and now that it's here, I can actually take a look to figure out which one. I'll put some pictures up too. The engine is not seized and rotates easily (not TOO easily of course!) The IOE engine is pretty cool up close. The spark plugs look fairly new as if someone had replaced them during the last "renovation" on it. The paint is not original but they have done a decent job overall. Some of the parts that were originally painted are in new chrome it seems. Tires are OK, but definitely not original. Has a cool Prest-o-lite headlight but no canister or acetylene setup. Also has a horn on the left bar. Twist throttle works well, and the left twist grip seems to do something with the ignition timing at the Bosch magneto (retards and advances?) It also has a linkage that goes into the right side of the engine so I'm not exactly sure what that does. I'm used to 1970's Japanese bikes, so bear with me on this one.

    First things first. I'm thinking it's not a bad idea to change the oil. What should I use? And same with the gas. Do I use non-oxy gas and that's OK? From what I understood, tetraethyl lead (lead additive in fuel) wasn't main stream until the early 1920's. Any info on this would be great!

    Second, with plugs out, I can turn the engine over with the pedals. Doing what I would typically do with a Japanese bike, I'm looking for spark and I have none. Is there any special trick I'm looking for to get spark? An older mechanic around me thought there might be a "special" spot that you would need the advance in to start the bike, which makes sense because if it's too advanced or retarded it won't fire properly.

    Lastly, I've been searching all over the place for a workshop manual for the bike. I've checked ebay and had no luck. Checking local libraries next. If anyone had a line on one it would be greatly appreciated. Thanks for looking and thanks in advance for any answers and help!

    There was no workshop manual back then.The right side controlled by left grip opens the exhaust valves[compression release]for pedal starting.10F would have a lever on gas tank with linkage on right side to rear wheel 2 speed hub,Chrome didnt start until late 20s but nickel plate was correct in '14

      Great info. This one does indeed have the lever on the gas tank with linkage going to the right side. Maybe some of the chrome parts are actually nickel plating then. And now I'm understanding what you mean by the linkage on the right side that goes into the engine. What a cool idea. Do you pedal a bunch with that open and then twist it back to allow compression then? Thanks for the info so far, this thing is just amazing to see in person, and learning all about it has really humbled me and brought back a passion for motorcycles that I haven't had in a little while.

        Twist back advances timing and closes exhaust valves---nice bike

          Thanks. Every little bit of info helps I wish it was mine maybe some day I'll own something like this. )))


          I found this info today I think it's for a 1920's magneto, but looks pretty similar to the one I have on the bike. The person didn't give permission to share it on any other place than the 2 websites listed in the article. So I've put the links to the page for other's to use as it's a great resource.

          Magneto information:

            Just slowly pulling her apart. Here's the latest update. I haven't pulled anything off that wasn't "easy" to do so. As in, I left the mag on there for now because I don't want to disturb timing or anything by taking it off with the wrong procedure. There is a gentlemen kind enough to lend his words in a private message and I will call him to ask more info shortly. I'm trying to put some of this on here as a record for future owners of these amazing motorcycles. This one has some stripped out screws and missing parts as one would expect. Just amazing to have my hands on her.4.jpg3.jpg5.jpg6.jpg

              Carburetor removal.

              The main thing I would like to note about removing the carburetor from the "T" piece that holds it in place, is that the nut is REVERSE THREAD. I was looking at it and noticed it had quite a hard life, and looks like it was over tightened. I took my breaker bar and tried to remove it as per normal (counter clockwise) and noticed it didn't move. I was barely putting pressure on it, but with the breaker, I should have seen some movement. So instead I thought if it's that stuck I'll go clockwise slightly to break it free. Well wouldn't you know she just loosened right up! I now know why the nut's edges were rounded off. Several other attempts have been made on it's life

              Secondly, I would like to ask if anyone knows how I should remove the exhaust from the fender. I know it would be much easier to deal with the rear wheel and drive train if I could remove the rear fender and attachment points. Any help would greatly be appreciated.

              Now for the pics of today's adventure.7.jpg8.jpg9.jpg10.jpg11.jpg

                  I've got a replacement float coming in now. It's specs are just slightly off from this one, but it's the closest thing I could find. Looking into taking the magneto off next.

                    It's been a little while. Just thought I would update. Float has come in. Working on getting rear to TDC and then removing the magneto for inspection and send it out to be rebuilt. Hope to have something on this over the weekend coming up. My second child is due in a week, so we'll see how that goes...

                      Motorbikebruno!

                      If I may ask, as it confuses me, which of the float's spec's are "slightly off"?

                      It's just its size, I hope...

                        Got the rear cylinder Intake rocker out and intake pocket out too. Pretty neat design.

                          The inner and outer dimensions are correct or very close at least. The thickness is a bit thicker than the original. I was told that I got it from a good source, and they also said this was the one to use. I'll try to get pics of the carb going back together. But it's really not a big deal, I'm fairly certain this is the best float possible for the beast.

                            Good news to report currently. Got the magneto off without incident, rear cylinder is at the correct spot for timing after the magneto is serviced. Working on that next! Most likely sending it out to a professional rebuilder of them.

                              Cotten, I finally got around to looking at the floats. Relatively close in all appearances and measurements (except thickness). The new one FELT heavier. And I was right. It's nearly twice the weight of the original. I can file down the new one to make it thinner and more close to the original specs and then see what the weight is from there. I just don't think the float will work properly if it's twice the weight! If I'm wrong and the new material is somehow more buoyant in fuel, please let me know!

                              Thanks!
