    Hey all, new to the forum. Just picked up a 70' HKO and was super excited, so far I hate it haha. Have spark and enough compression to start. Pulled the tank, drained it, got good flow and installed new charged battery. Was expecting to turn the key on and have lights but nothing. No headlight, tailight or horn. Pulled the ignition switch, headlight, checked connections etc. Nothing. Moved in to carb, the slide was backwards, cleaned jets. The pilot must have the teeniest hole ever but I did the usual and was able to see through the worlds tinyest jet hole. Floats are crumpled in but did float, also took on a bit of gas. Tang looked bent way down and needle valve did spring up and down tbit seemed weak. You guys lean towards rebuilds or repops? Put the carb back on, no start, gas seeping from inlets and the drain hose. Guessing it was too flooded to start. Before that it did run after pulling the slide out, gas in carb, fired, idled high and died once it burned that gas. Will live to fight another day but after kicking it and the kicker arm came off i had to give it a break and see what feedback I'd get. Is there a main fuse? There is one in the inline battery line but I'm not seeing another. IMG_20200718_171737496_HDR.jpg

    Well I have to take back everything I said about hating it. After my meltdown I went back later last night. It started, I rode it, and as you all know, ear to ear smiles! I ordered a new float, pin, needle/seat as I think that's the main problem with the carb. Would like to get a full rebuild kit too now that I've been pointed to a good one. The float tang was bent way down so I leveled it, probably too much as it drains out the carb plenty. Weird thing is the lights just randomly started working after the bike was running. Should they come on when running a battery and turning key to second position? Or do they only run when the bike is running. They also do get brighter under throttle. Gonna change oil this evening and do some cleaning up. The rear sprocket has some wiggle/play in it so need to address that and get my chain tension better/see if it needs a fresh one. Super happy though over to get it riding again!

    Make sure youre getting everything you need in the carb rebuild kit. Not all kits are created equal.

    I noticed that and have learned the hard way from other bikes. Gonna go with the recommended above.

    congrats on the new bike. as for the intermittent lights I would start in the headlight bucket looking for corroded or loose connections. with it being a different color I would guess someone has been in there.lights dont have to work to rip up the neighborhood though. enjoy.

    Intermittent lights can mean a ground problem. With a 50-year-old wire harness, it's not uncommon to find a broken lead in the bundle located between the frame grommet and headlight shell. Time, flexing and brittle insulation can gradually break all of the copper strands inside a single lead...and appear to be intact, visually.

    As for sprocket wobble, the countershaft sprocket is supposed to be loose and have quite a bit. It was that way from new. The wheel sprocket should have much, if any, wobble. However, it is a friction-fit, located via 4 rubber dampers and piloting off of the hub nose. Those dampers do wear out, eventually; rubber can also dry out after 5 decades. Sprockets & rubber dampers are readily available, new. As long as the hub nose is still a reasonably snug fit inside the sprocket bore, the hub is fine and could last another 50 years.

    Oh the neighborhood was ripped for sure. I did exactly that with the bucket and found a couple terms unplugged. What is recommended as a good cleaner for those cuz I ran out of the electronic cleaner I had. All lights working now just no horn. I'm now waiting on my carb rebuild kit and float as the float was crumpled and taking on gas so it floods bad and won't start. Only way I can get lucky is to drain the bowl and kick away hoping for the best. Probably gonna paint the bucket black just to look better as this isn't a bit restoration just a ripper. Got the infamous bent bars to deal with too.
