    I didn't do anything on my own bike recently, but i did set a new record today. Fixed *seven* bikes. It's a thing I do in my free time: if any of the neighborhood kids have bike trouble, I fix their bike. I like them to be safe. Five were newer ones I hadn't seen before. Some of the kids have grown a bit since I last worked on their bikes. Two just needed air. Three needed the chain put back on and the rear wheel adjusted. Two needed a new inner tube (of which I happened to have spares, and that's why I scrounge for discarded bikes and parts on my walks - free parts).
    One poor bike needed almost everything, poor kid. His dad did the best he could assembling it, I think, but something tells me he had trouble with it. It may have been his first time doing that. The front fork was on backward, ruining any hope of rake-and-trail. The seatpost was just sitting in there, so I tightened it down for the kid's crotch-height. Had to adjust the wheels and chain, air up the tires, swap the brake handles around, adjust the brakes so they made contact on the rim correctly, tighten down the headset so it wouldn't rattle the kids teeth on every bump, tighten the loose pedal, and I think about three other things.
    He loved it. He said it was like a new bike. I got choked up a bit, 'tis true. He offered to mow my lawn and pay me money and stuff. I told him to just ride his bike safely and have fun; I have my own lawnmower. Hitting the asphalt is not fun, I like to think I can spare them a bit of that. That, and I just like working on bikes to be honest. But I'm tired now, and so the neighborhood bike shop is closed for the day. Well...unless it's like an "emergency", then maybe...

    Hopefully the kids see what you do and learn how themselves how to repair bikes. At least the older ones. One day my dad said look how I repair the flat. I was maybe 7 years old at the time he mentioned, this is the last time. Except he added if I had trouble he would help.

    That's a good one. I in a pinch used Vinyl Electrical Tape to fix a flat when I rode about 5 miles from home with out patch kit, but had a pump. I took the tube off the rim without taking the wheel off. Can be done with bare hands. Then pumped up to find leak. While still hissing and puffed up a little, used the tape a few times around and then deflate mostly to put all back. It lasted longer than the frame for years. Never did it the right way... so what is right?

    Some of the kids are catching on. But some come from a house where I seriously question how many tools their parents have. "Economically depressed" is an apt description of the Mars Hill neighborhood. The one older kid was helping out though; he was taking the nuts off one rear wheel while I was finishing another bike. And I walk the kids through what I'm doing each time, to try to give them an insight into how bikes work. But if business remains brisk, I may have to train an assistant.

    That's really nice, Allen, helping those kids that way. It makes me feel like a selfish rat cuz I went out and fixed my own bike. haha
    I haven't been riding or posting for months cuz I've been under the weather as they say since New Years and only this week felt like looking into the trouble with it. A 2 stroke Dax, it had lost power on its last ride and wouldn't pull at all.
    I drained the old gas, cleaned the carb's passages and jet, checked the float, tightened the intake, checked the seals, looked for air or oil leakage (nuthin), took off the head for a look in there (nuthin) oiled the bore and put it back together. Aired up the tires and gassed it up.
    It runs fine again, I reckon it had some grit in the jet or float passage, starving it for fuel. It actually started right up and idled good cold.
    All's well. I do have to pick up a speedo battery, its going down fast.
    Fall's almost here, the best months for motorbiking.

    Ruined my rear wheel by derailing the chain and it fell between the sprocket and the spokes and ground them up. Got some awesome new wheels machined. I based them off of teny rims, but I wanted to put fatter tires on them, and so I had custom ones made. The entire wheel is made from one piece of magnesium alloy.

    Pooh! Ol' Tempus is being a real pain for the first time in many years. I should probably count myself lucky...but that'll be easier to do once everything is taken care of. I at least fixed the shorting problem in the headlight (a screw terminal had loosened far more than I thought possible). And I modified the brake light to a much brighter LED bulb. But I still can't figure out why Tempus won't stay running! I've cleaned the carb, checked the float and needle, and checked that I have consistent spark. Plug isn't fouled. That leaves a clog or deposit someplace in the fuel line, causing it to starve and bog and stall at random. Boy, I'm going to love tearing things apart looking for that. yay. woopee. Tomorrow, the endeavor begins.
    In other news, the local kids have been bringing me tires to air up, and seats and handlebars to adjust - due to growth spurts. It's only been a year or two and already Jaden and Cadence are noticeably taller. Those little 20 inchers of theirs which I've tinkered with off-and-on: their parents may be replacing them this Christmas or next. I've lived in this neighborhood since 2009 - I remember when some of these kids had just learned to walk and would stroll by with their parents holding their hand. Now some can almost keep up with my motorbike in a short sprint. Some have been watching me pretty closely, so I've been showing them some basic maintenance. I've told a few that, in another 8 or so years if I'm still living here, they may want to bring their adult bikes around and I'll help 'em do a thorough check-up. I like this little neighborhood. Most of the kids here are pretty healthy and slim and ride bikes all over. Some have told me they don't even have any video games at home ('though they do have computers at school). I tell them they won't miss the video games that much later on, and video games won't take you places or keep you fit. A few of them seem to get it; they really treasure their bikes. It's a good thing to see.

    Allen Wrench, I once had a fuel valve that I could not take apart to see why the flow through it was bad. I eventually ran enough gas through it and moved the valve open a shut a number of times and then it got I guess some gunk out. The I hooked it back up to the carb I clean all out and was fine. I may still change the valve one day if need be.

    As for kids needing bigger bike, I did partially that. I'm a big kid;) Just for laughs I adapted a 24 inch wheel bike for a Burner bike for one of the times in the past attending Burning Man Event. The seat post I got was high enough for my legs, but then I had to lean to far forward and down to reach the handle bars. I eventually welded even smaller handle bars from a really small kids bike on top of the existing handle bars. Four hand grips take your choice.

    See "Art Fish Mobile Motor Bike prior Motor Bike DIY'er build to add side car maybe?"

    I've yet to take the motor bike built now using for off road riding and make it an event bike. I have the thing started, but need time to get to it and so later. No ticket this year to the Burning Man Event, but have looked at some pictures of some really good sculptures and mutant vehicles.

    I upgraded from a 2-piston Hydraulic front to a 4-piston TRP hydraulic brake. This one was a rear so I had to shorten the hose. It comes with a bleed kit too! $120 not bad at all for a quality single brake and nothing additional needed. Unfortunately my 2-piston wore right down to the pad backing and ate up some of my disc, so I had to replace the disc too. I liked the look of the old disc better, but this one is ok too.

    This brake will also take the shimano heat sink pads. Nice to know as many shops carry shimano pads more than any other brake.

    It was yesterday actually, but... I set up a pair of crappy stock tensioners, replaced the bent pivot bolt in my forks, smeared Loctite on everything, and fired her up! All that's left really, is to replace my busted throttle assembly, everything else is more or less optional.
    Despite my mushy gushy throttle I took her around the block, even pushed my luck up to 22mph. She rode pretty dadgum smooth. She needs some better brakes, but I need to ride some before I can comment further. Today, it raineth.

    new exhaust. it's super nice, although i desire a little more top end and will need to change the crank to a wide crank to avoid the exhaust with my foot.

    I spooled Murder out to 38.9. Felt like the Dax motor wanted to spin even faster, but the rings ain't seated yet, so I backed off. I'm being just as gentle as I can bring myself to be. Got paid today, so I might just order my SBP pipe today...

    Well, since the city has decided that the smaller potholes in certain neighborhoods are no big deal, and seem inclined to fix them when they feel like it, I have dug out the old springer fork from the original incarnation of "Tempus", dusted it off, and began prepping and painting to match the current blazing red paint job.

    I also made a brass fuel-overspray shield for the tank. Fresh pics here on the old thread I bumped:

    Loaded mine on the back of the car to accompany me on 4 days of camping in NW Arkansas..........going back to the same place as pictured in my avatar. I fully expect the bike's top speed to be about 75mph on this trip.
