Default Re: Motorized Bicycle Take a Tip...Leave a Tip

I got mine from ebay, one color was the good stuff and the other color was something else and it did harden everywhere but where it slid over the barb, then it began to leak after a few months, the good stuff has been there on my other bike for about 4 years with no hardening or trouble, I do remember there was a significant price difference, but I wanted my lines to match the color scheme, and I found out the quality difference later.

This tip does work with just about any flexable plastic tubing and possibly even with the harder plastics, not so sure about teflon tho since it has a really high melting point, (a heat gun and a steady hand may help for that tho) but it may work with small diameter pvc (not for fuel of course, but other uses one can think up).

I saw this tip else where on Youtube, but I did not go looking for hardware to make what equates to an extra hand to hold down the top of the valve while attaching the cup or pin to the valve stem.

Used one of the head bolts and extra shroud part of metal with the exact size hole for the head bolt. I needed a shim and use a socket that worked. Then with the valve spring compressor and a needle nose pliers had it an easy task putting the valves back in after adjusting and lapping.

I don't currently recommend a cable driven speedometer/odometer, At least on my e-bike it made a lot of extra noise I was not accommodated to and to boot it read twice as fast as my cycleanalyst digital speedo would read. I'm pretty sure its for a 26 inch wheel , But what with having a springer front fork It was a bit wonky to install. Then when I hit the railroad a bit hard I think something got knocked a bit outta whack as the needle started jumping up and down for the rest of the ride. Overall I must say Im quite dissapointed.
not super technical or probably useful info as who the heck wants to use a cable driven speedo?! Oh yeah, I did because I was going by the rule of cool. why isint there a wireless Analog speedometer for my ye olde style bike?

Ok... that's more clear...
Now if you still want an analog speedometer for your bike, they do make electronic speedometers for motorcycles and mopeds that run off a wheel sensor or magnet and pickup that eliminate the need for the twist cable and the gauge itself has an analog needle instead of the digital readout.
i'll se if I can post a link since I've seen these on ebay before.
When my speedo went out on my '84 KZ 700 I didn't want to use an aftermarket gauge, but a bicycle speedo was easy to install and remove, I just stuck a rare earth magnet on the brake rotor and it stayed put, even at 120+ mph (whatever the bike's top speed was) and the actual speedometer could easily be removed when I needed to show off the bike and put back on when I went out for a ride. I really don't like digital, but it was cheap and easy, there are analog ones available now, but take some searching on ebay and other places.

There's another alternative, but probably too expensive, some of the bigger name car gauge companies are making GPS speedometers that are surprisingly accurate with analog readout, they take speed samples 10 times a second so the readout response is just as good as mechanical or electronic, but only one wire is needed to power it. The drawback... they cost over $300 still.

Here's an example of an electric speedometer after searching "moped gauges" on ebay... I'm sure you'd need to find a sensor for it, but it can be done... http://www.ebay.com/itm/Speedometer-...03377226&rt=nc

You know it never occurred to me to search for moped bits. Thanks for the new line of parts Davezilla!

No problem... That's why I asked about the tip part of your post. I can usually help or at least steer ya in the right direction once I understand what's going on.

Here's another valuable link for goodies... http:www.treatland.tv they might have something better than the ebay stuff or the speed sensor needed to make those speedometers work.

That could be worth the money if it doubled as a tracker for my bike. I've been thinking about a GPS tracking unit anyhow and if it happen also tell me how fast I was going While looking really
Cool I could be down with that...although my original plans were for the tracker to be somewhere in the Bike frame
