OK, I believe you. So then how did my old exhaust mount? Because I know it mounted onto the swing arm.

Your exhaust mounts to a bracket that mounts to the frame. You can download the workshop manual here: http://www.carlsalter.com/motorcycle-manuals.asp

Once downloaded take a look at page 70.

You can't do that. At least shave the seat with the needle and abrasive just like you'd seat valves. That is, if you insist on using hours to save a $10 part.

What you suggest is the sure way to make things worse. Fat chance getting a closing cone with a cotton swab.
the idea is to not grind it to shape but instead polish it and remove any varnish/dirt that's preventing a good seal. it takes ten minutes of work, not "hours"

i've done this trick successfully on quite a lot of bikes

So i saw this thread and really got me interested in buying and restoring a old bike to commute around town.

I went on craigslist and found this:

http://sfbay.craigslist.org/nby/mcy/1890391186.html

how hard do you think it will be to restore something like this for someone with no automotive experience? Im good at reading and following directions just never really messed with anything automotive.

It looks trashed. The gas tank is built into the frame, and if that's significantly rusty then the frame will be compromised.

I prefer solid tube frames with separate tanks as opposed to tank-in-frame mopeds, so I'd say get a Swinger/Pinto/Freespirit. The E50 is incredibly simple to work on and rebuild, and parts are cheap.

When you're feeling more confident go buy a Hobbit and don't look back.

As a Derbi owner, you don't have much to worry about, but Hobbits are great because they are case-inducted bikes with reeds and are dual variated, and have plenty of performance parts. Dual-variated means there is a variator up front and a pulley in the back, so it's essentially like having a continuously variable transmission, you are always in a good "gear". They are also ridiculously easy to make hit at least 50 with bolt-on parts. $250-300 Hobbit + $150 DR/Polini/Parma/etc kit + $110 Proma circuit + $6 jet + $15 reeds + $5 clutch springs ($20 clutch remover, though) + notched variator (free through owning hacksaw and rotary tool) = sub-$600 50-53 mph blaster that takes off like a rocket with power everywhere that took you an afternoon to put together.

Something is wrong with my Hobbit carb SOMEWHERE, though, either the bowl isn't filling fast enough due to a clog in the fuel inlet to float intake (doubtful) or something is wrong with my float/float pin. I'm running out of fuel on WOT runs all of a sudden. New petcock, new fuel line, new filter, clean carb.

However I think Swinger/Pinto/Freespirits are about the ugliest things on the road. So ugly they bypass the "this is clearly something I ride without taking myself too seriously" realm and into "this is loving hideous" territory.

Agreed on the E50 though.

Oh I love learning about things like this. Mopeds just keep fascinating me. I want my derbi to run so badly. But now I need to figure out how the hell to mount my exhaust to my frame since I don't have a subframe. I am incredibly thankful that not only did I not destroy my exhaust, I don't even have an air leak :D

$300, it wasn't a super steal or anything. A friend picked it up a month or so ago and tried to sell it for a lot more, but didn't put enough effort into it. He needed money for school and was tired of having it, so he just let me have it for what he paid for it. It's actually more like a 7/10, and it's a II, not a MKII, so it's non-hydro forks and spokes. I could flip it for 5-600 no problem, but I'd rather keep it, as it's one of the bikes I've wanted since I got into peds.

I'm swapping my entire power train over from my Maxi and the freshly powdercoated black mags as well, so it will be pretty sweet and clean enough to turn a few heads.

It's just a goofy looking bike. :) Unlike some of my friends, I don't find something to love in every bike. IMO, if you want to find out if a bike is worth buying, search on treats to see how many performance parts there are. More parts = more options = more fun.

Alright cool thanks. I was just like looking for a general opinion like "Oh yeah I heard they're good," or "They have some serious problems"

Just a tip in the right direction is all. Checking treats now.

edit: So there is nothing but one part on treats. Thats fine if its not customizable, I'm looking into it for a friend who just wants a sturdy, solid, speedy ped. What is this things power? It says its 50cc so its basically like most standard peds in terms of speed and capability? What is its gear ratio?

There is plenty of stuff you can do to make a qt50 fast. The question is how much do you or your friend like to take stuff apart and cut things up and make them fit. You can make any pipe or carb work with enough time and access to tools and the skill to operate them. The malossi kit is supposed to be pretty sweet like everything else they make. There are easier and cheaper bikes if you aren't interested is serious modification or fabricating parts. Any puch bike or anything with a minarelli has an abundance of cheap parts.

Everytime I hear about some domestic tuner doing something crazy and making a bike that can hit 70+, I see some Turks or a european going like 85-90+ on YouTube.

Also I need to learn what it is about Motobecanes that allow them to be SO FAST, even at 50cc. Some domestic guys just go apeshit on the cylinders and can get over 60. You need a strong kit to do that even on a dual-variated Hobbit.

Edit: also, in my moped news, putting M bars on my new Magnum changed the bike so significantly, it's phenomenal. I love how it rides now.

I don't know if this counts, but I've been building a bike similar to LobsterboyX's Whizzer.













It has a 49cc 4-stroke engine mated to an EZ Motorbike automatic transmission and some modifications to make it a bit safer, including a front disc and brake light.

As of right now, it won't run for more than a couple seconds. I'm hoping it's just in dire need of a carburetor adjustment. School and work take priority over it at the moment, but I hope to get it sorted out soon. The weather is wonderful right now.

It's a new Tomos.... so... not anything I like to recommend to anyone just out of my prejudice on basically any moped made past 1985.

"Some sort of aftermarket exhaust" - I'm going to guess BiTurbo. :)

If you like it, it's worth what you want to pay for it.

Got mine running, finally. Air/fuel mixture had been set way too rich from the factory. I got it halfway down the block before the chain got bucked off the rear sprocket. I had already shortened the chain once. Hopefully removing another link will fix this because the chain tensioners that come with those kits are garbage. One company makes a spring-loaded tensioner that mounts to the seat post, but it's like $40. F that S.

I've got a 84 Garelli Basic and an 80 Puch Newport II. Currently in the over-my-head process of rebuilding the ZA50 transmission. I'm hoping to eventually put a pipe and carb on the newport for easy high 30s low 40s..

Those are the standard Magnum XK/II forks though, yeah? The Hydros have the black wiggly covering up top.

I will say the suspension on my Magnum II blows away my Maxi.

ODB what kit are you running on that? Looks like a K-star or something? I want to think it's a Polini but I'm not sure. I just put a Estoril on my K-star because I was sick of the noise of my Circuit with a hole in it near the exhaust port. I think the overall powerband is superior, more torque at high speeds too, but I lost about 2mph on the top. I don't want to get the restrictor removed either, because that's what makes it such a great pipe down low. Once I move to a Polini setup I won't care anymore, anyway, because I'll be back over 50.
