A good motor/controller/battery combination will cost around $2 grand alone. Mid-drive electric bicycles often have the motor output shaft on the right side, a freewheel on the pedal crank and then some crazy expensive internally-geared hub like a Rohloff 14-speed which is over $1000 by itself.

I see these folks are using dual sprocket wheels so standard moped stuff will work on it as opposed to Motoped, which uses standard bicycle parts that are not really suited for motorization and then break.


I've ridden it and it's super duper fun. Essentially it's a really quiet puch magnum.

Way way back when i had my Moby that's what I did. The pedals sheered off, and this was like back in 96 before good info was available. Had it tuned to the point i could get it rolling and it'd kick over rather easy. The switch to kick it over from power to pedal always hosed the thing up anyways to the point i had to pull it apart and reset everything anyways, so it wasn't much of a loss.
It was a good moped, not the quickest off the line, but could catch up with anything the other guys were using except the little Express I had. that fucker was quick, just could never get the fuel system to stay sealed so one day it caught fire.

For sure, and I'm putting a launch lever on it next so the pedals would've interfered with that as well.

Good call on the coupon code by the way, I guess I just didn't want to be a dick and ruin his attempt to get more email sign ups.

Last question, anyone have somewhere where I can find the dimensions on a Cobra versus Magnum? Been looking for a Magnum, but could get a really good deal on a Cobra right now but I'm worried that it might be way too small for me (6'1 220 or so). The Moby fits like a loving glove and still rides great considering how much weight I'm putting on it.

The Cobra is essentially a top tank pinto. I'm 5'10" and find then to be too small for me to comfortably ride but you might feel differently.

That's what I figured! I've seen one but never ridden one. People still seem to want absurd money for Magnums (when they even come up on CL) so I guess my top tank dreams will have to wait for another day.

Every time I think that I should just get a motorcycle I remind myself of how much easier it is to abuse bike racks.

I would join the Facebook moped swap page for Chicago. Prices usually are a little better as people get called out when they try and sell bikes for too much. You could keep your eyes open for a free spirit and make/add your own tank and skip the crazy prices for magnums up there.

This is the word I've seen a lot on the net.

It's got a mechanical clock spring starter that you kick once or twice and then release by gripping the rear brake. in this sense, it' pretty similar to a moped but then again- no pedals.

I've started going through the wiring and hoses and I've found that the soft fuel lines are starting to disintegrate on my NC50.

They seem more rigid than the regular rubber soft lines that I see on cars. What should I use to replace them?

Go to autozone/oreillys/etc. and buy some of this http://www.oreillyauto.com/site/c/detail/GATR/27001/N0887.oap?ck=Search_fuel+line_N0887_-1_1217&keyword=fuel+line&pt=N0887&ppt=C0222 . You can also buy hose in prepackaged lengths. This won't get super stiff and shrink and crack like the clear plastic garbage so many people use.

Yeah I generally think it's worth it to get nice fuel line. The cheap stuff is like one-time-use at best, a lot of them harden over time and lose all flexibility. And I mean over not much time, like a few months.

Mine is still pretty soft. I removed it to test the petcock and it seemed like it was in pretty good condition.

There's really no reason to go cheap on this in my opinion. Even going premium on hoses and wiring components is going to be a really cheap way to ensure reliability.

I put some more time into the Express.

I got the headlight attached but it's got an aftermarket lens with replaceable bulbs so I haven't finished that bit yet. Once I get the wiring completed and the oil line mended, I'll fill it up and try to start it again.

I would highly recommend bypassing the oil system. Theyre old and prone to breaking, just run premix instead.

You have to carry around a bottle of oil and a measuring device for every time you fill up.

You either have to carry oil and a measuring device around, or carry a can of premix around, both of which are lovely options. Also it's harder to jet properly with premix.

I guess if you just ride in a small radius, but if you go for longer rides, those options are annoying

Some 2-T bottles have measurements built in, and the amount you'd need to carry is minimal considering a moped has a sub-gallon tank in many cases. It's really not THAT bad, and it's one less mechanical thing to fail -- one that could cause seizure if you don't realize it has failed. Compared to theoretically cleaning the piston/chamber a bit less often (which requires removing 4-8 nuts at most depending on if you're removing the intake/exhaust as well) and taking 15 minutes to clean maybe once a year, it's not a huge deal to just remove the thing.

That having been said, if the pump is in good shape I'd see no reason not to keep it, and if you're attached to the concept, there's really no problem replacing it. There are benefits in both directions, but "having to carry a tablespoon of oil someplace" isn't really that hard of a thing to deal with. My Puch has a tiny compartment under the seat that holds the oil, an extra sparkplug and a wrench. I'd just use a bicycle saddlebag to hold puncture kits and such if I was planning on using it more extensively.

A 3oz bottle of oil with measurement on the side. How lovely for you. Don't worry, I'm starting a gofundme for you to finance a guy to follow you around and carry it for you.

You should probably get mad about this.

I'm saying if your pump works, use it. It's easier in every respect. Plus if your engine has any manner of modern lubrication system, it's pumping oil straight to the lower bearings, something which only happens sporadically with premix.

Then there's the jetting thing, which is tougher with premix and varies on every single tank because you are never mixing exactly the same ratio.

Also, those little mikuni pumps that literally everyone used back in the day are actually pretty drat reliable.

I am of course speaking mainly about Japanese bikes, ymmv outside of Japan.

How!
Oct 29, 2009

I dunno, I always delete the oil pump on za50s because those are really bad.

Re:jetting, unless you're running a crazy race build and revving to the moon, there's pretty much no way premixing gas is gonna mess up your ratio unless you just accidently dump the whole bottle in there. I have a polini'd Ciao and I literally eyeball what I think is the right amount and my temperature never rises above like 320 degrees.

For real though, tens (maybe even hundreds) of thousands of moped riders run premix and there isn't a never ending parade of kits being seized because somebody didn't use a micropipette to calculate their oil ratio at the gas station. Your paranoia/inability to tune a bike because it is 45:1 today instead of 50:1 like it was yesterday is pretty funny though, Jim.

I've run plenty of dirt bikes that were premix only and was able to do it just fine thanks. Ive also run lots of injected street two strokes and premix is just obnoxious for the street and I'm sorry if you can't see that.

This also has nothing to do with my ability to tune carbs and everything to do with the average persons inability to tune carbs with premix, yours as well apparently because lol if you think "Well, it didn't blow up :shrug:" is in any way a replacement for (or related to) actually being jetted properly.

So anyhow:

I'm guessing plug it off at the tank- or I could install a petcock and just leave it always off. I get a small amount of seepage from the fuel side into the oil tank anyhow.

Then on the oil pump side- I should probably seal it off to prevent particle intrusion then yes?

Q: At what point does retarding my timing become dangerous? Based on the assortment of scratches on my flywheel and my own bumbling attempts at timing my first rebuild, I believe my points are opening around 13-14deg BTDC. My woodruff keys don't fit the race crank I bought, so the flywheel is too crooked to hit 17deg like the manual says, but I was planning on retarding anyway and the bike is actually running pretty well.

I am running a 15 bing 82 jet 19T front sprocket on a 50cc. My idea was to jet/gear/time it for top speed and try to recover some of the low end with a hi hi comp head from treats and my pipe. There's no flames coming out of the exhaust, but if you squat you can see fire in the header when someone gives her a bunch of gas up a hill.

Is this thing going to explode on me? The plug is wet, sometimes, but she's not four stroking and I'll probably try an 80 jet once the break in is over. I'm under the impression that A) Advanced timing + high revs = grenade. B) Richer runs cooler. C) Retarding moves heat out of the cylinder and assists with exhaust velocity/scavenging at high rpms. Correct me! :allears:
