K-star is a brand of kits. Treats doesn't list them on his site as k-star, but that is what his "treats 50 and 70cc kits" are in case you are interested in researching performance parts before you buy them. I actually just finished putting one on. Now if only my jets would hurry the gently caress up and get delivered so I can actually start it up.

Cool. Let me know how the jetting goes; that's my biggest worry is that I'll gently caress up the chop and not match everything well. It sucks because all reviews are more or less anecdotal, but I grabbed the Boss because it's supposed to have a fairly decent midrange on top of the highend, and it'd be nice to have something that's all around decent to ride (on top of 2-stroke peaky yay).

I get off early this afternoon, so as long as it doesn't rain, I'm gonna go through my new toy to see what needs cleaning and what just needs tightening etc...

I live in Kalamazoo and I'm looking into getting a moped, and I've been looking at a Puch Magnum. How much should I expect to pay for one in decent condition, with some rust in a few spots? I've seen a few sellers on Ebay listing theirs for around $800-$900 but that seems awfully high, I was expecting something more in the $400-$500 range.

Go on Craigslist and wait for a deal. Around Boston, you'll see a lot of top-shape 'peds at the $600-800 range, especially in Spring/Summer. Those same bikes go for $300-400 come fall/winter. Sometimes you get lucky and find someone who just wants to get rid of theirs, and other times a simple problem will save you a ton of money (20 minutes to clean the carb = $500 off? sure!). I don't recommend that second route unless you know what you're doing and looking for, though. Or if you're interested in fixing as well, I suppose.

I hate Ebay for the inflated prices. Try mopedarmy as well; they tend to be kinda hit or miss; some folks thing their peds are worth way more than they are, and others realize the community knows the value of certain things and give a fair price.

Well, that stuff and Magnums are one of the most coveted models. Expect to pay a premium for a good condition Magnum. The thing is, while they might start off high at 800-900 dollars, even if it was only 300 to start with, the bidding typically takes them up to the 800 dollar range by the end of the auction anyways. Luckily for you, Kalamazoo seems to have a pretty good moped scene. As stated above, scour craiglist and you're sure to find something. Also, don't hate on Ebay. My I got my favorite moped (2001 Tomos TTLX) for only $200, and all it needed was a carb cleaning.

Why is the Magnum so coveted? Is it that it's a top-tank rather than step-through?

It looks more like a real bike and is nice and stable for higher speed modding. I only paid $500 for mine and it is immaculate, so don't think you have to spend 8-900 for one, you just might have to wait for loving ever to find a great deal.

I was looking into articles on Moped gangs (because the idea is cute to me), and I found a few things.

1. Apparently, I'm not the only one who thinks the idea is cute, since every article from San Francisco to New York mentions the idea as such.

2. Please tell me this isn't a common term:

He brought it down in the back of a pickup with his son, who was just entering college and had apparently exhausted his moped phase by age fifteen, as most mopedophiles do.

I picked it up with intentions of having it be a wife cruiser, but she's not interested in messing around with premix, or smelling like 2-stroke, so off to the chopping block it goes.

I've heard the term mopedophile, but it was being used for the purposes of humor. I'm having some issues with my jetting. I'm not getting a nice coffee color on my plugs, but I'm 4 stroking on the very bottom end and the top end seems sluggish like I'm not getting complete ignition. Would running a hot plug(ngk bp5hs) make my plugs appear lighter? I have jetted up from a 70 to a 74 to keep from siezing during break in, but it was definitely a lot faster on the 70.

George RR Fartin
Apr 16, 2003




Is there any problem with using a colortune rather than a plug chop on two strokes? I'd like to be able to use the most accurate and least frustrating method of figuring out my jetting. The only worry I have is that the 2-stroke oil would somehow compound things, but if it won't, I may just splurge.

Youv'e answered your own question. You're pig rich. Lean it out, and you'll be better.

You don't want "coffee" you want "almost white" with a light tan at the base of the insulator.

What carburator are you using? On what bike? With what jets?

George RR Fartin
Apr 16, 2003




So I figure I'll get the 'ped running right before I try improving it. The carb was dirty as poo poo, but simple (this is coming from a rack of Keihin CV's on a CB750), so I soaked it in carb cleaner and did a bit of e-string magic on it.

I go outside, and the ped's out of gas. That makes sense; it was on its side when we picked it up (in the back of the Altima) and it leaked a bit onto the towels we laid out. The kid I bought it off said he had enough fuel in it to try to get it running (it wouldn't hold idle; thus the carb cleaning), so I figure that's why it's empty.

I drive out to the gas station, fill my car up, and fill a gallon container. I drive back, and dump close to the whole gallon in the bike (it has a .7 gal capacity I believe).

Oh the float bowl is leaking. That's not surprising, but didn't I turn the petcock off?

I did.

Oh gently caress.

So now, after half an hour of waiting for the gas to refill the gascan from that tiny gasline, Treats is sending me a new petcock. And a floatbowl gasket.

By coffee, i should clarify, Coffee with cream, not dark brown. Puch magnum with a bing. I've been riding the piss out of it since I kitted it and think its well on its way to being fully broke in. I had a downjetted to a 72 a couple days ago and wasn't 4 stroking at all, and had to drop to 70 halfway through a ride because I started 4 stroking again. My top speed has been steadily increasing up to 41 mph on flat ground earlier today. Not too shabby for a 50cc. Makes me want to go up to 70cc and get a treats cdi(the full cdi kit is in stock now for $77, by the way)

Have you considered that a bike with a shifter, no pedals, and more than 50cc is a motorcycle?

People on motorcycles roll their eyes and call it a scooter, people on mopeds call it full-sized four-stroke weak sauce.

Trail bikes get no respect around here! I just want to know which broad generalization my tiny, underpowered motorcycle fits into, damnit.

Maybe I'll just tell everyone it was a 50cc but then I put two kits on it.

Moped report:

One '77 Puch Maxi is officially running again! I cleaned the 12mm Bing, stuck a new float bowl gasket on, put the new petcock on, and put some gas in the tank. It's an approximate 32:1 ratio; it may be slightly richer.

No petcock leak = awesome.
Slight float bowl leak = not unexpected. gently caress it; the 15mm Bing's going on to replace the 12mm when I get a free weekend anyhow (also a Tecno Boss pipe). The current 12mm has a 65 jet from the factory; I'm thinking 72-76 should be good with a 15mm and the new pipe. Sound good to everyone?

Niggling issues: The forks are straight, but the front wheel seems...off. Also the speedo doesn't work, but someone didn't put the cable back in correctly, so that'll be easy to fix. The brakes are a bit iffy even after I tightened them. The start switch does not work (I just choked it out to kill it). The tail light, similarly, does not appear to function. It wasn't lit at all, however, so it may just be dead and not miswired.

I'm pretty stoked.

oh, also

Kit Status: One DMP (K-Star) 70cc kit made its way to me in the mail from Treats, along with all kinds of jets. I'm not gonna bother with it until I've ridden around for a while, but chamfering is the first order of business.

Question:

My friend's (used to be mine) 82 Honda Urban Express won't run now, after having it running a while ago. We removed the by-starter because it was completely wrecked, and have been manually choking the carb (fingers over the throat) to start it. This worked well for a while, but now if you take the "choke" off, even after 10 minutes, it just dies. The carb has been gone through and rebuilt, and it's still doing this. Could it be something with the vacuum in the carb, or a float problem? I told my buddy to just pick up a new carb for it instead of messing with the 27-year-old Keihin. What do you guys suggest? I'm not terribly familiar with 2-strokes, so I'm not sure if there could be something else messing up (reed valve is good).

If you're finger choking it, does it have an air filter? If not, it's probably running crazy lean. Get a filter for it and see if that helps.

So i bought this Peugeot 103 from this 16 year old, it was a good price but over all i was weary about his skills fixing things. here it is:



Scoping things out i notice the throttle cable isnt connected and the choke cable has been kinda haggardly put on.



took the engine off and now im in the process of installing the kit he "installed", piston on upside down, not all the bolts were installed on the reed valve casing, causing an awesome airleak. hopefully ill get her running.
