Sell it to somebody who likes mopeds, and buy a motorcycle?

Re: is my columbia really that slow?

Look at the tag over the chrome cover. Should say 505/1 and then a letter B, A, C or D. B is the worse and D is the best in that order. One thing about stock Sachs bikes is that they are jetted rich from the factory so get a couple jets and experiment. Good gains to be found. Another thing you can do depending on the motor and or exhaust pipe is to cut the header back to where it just reaches into the baffle far enough to clamp them together. Some of these pipes are made in one piece so this isn't a possible mod with them. Get a new air filter.

Still need more. Get a bigger carb and a gianelli pipe.

columbias usually have A engines, meaning that the exhaust header is the big thing holding you back. a bigger pipe is the best way to gain speed but you have to modify anything in order to make it work unless you can find a gianelli pipe

Re: is my columbia really that slow?

A engines have the large header. Its the B engine that has the small one. The b also has the smallest carb at 10mm. All around the worst starting point. Looks like he has the square cylinder. So a C or D engine. Which is good if thats what it is. But I might just be seeing it wrong.

Re: is my columbia really that slow?

My bad. I just blew that picture up. Its an A or B cylinder on that bike.

Re: is my columbia really that slow?

hmm

spray pained black moped

no rear tire.

who steals a columbia?

Its ride in the pickup was prob the fastest its ever gone.

Is that the picture of it it "restored?"

Re: is my columbia really that slow?

Columbias have the tapered cylinder, a skinny header and a 12mm carb, and no ABCD on the label...

The Asil quich is a pretty good pipe for them, easy to install and makes them a bit faster.

Re: is my columbia really that slow?

no its not restored thats when i first got it..and for the retard that said its spraypainted........ are u really that stupid? its RUST

Re: is my columbia really that slow?

around here, we call it "patina"

no one buys a moped to go fast.

when you're willing to start dumping money, speed will come.

tons of wiki stuff on derestricting stock stuff, most mods will work on every ped.

free power = time spent finding it.

or you could pay someone to find it for you

i took 2mm of metal off a part, not expecting a dime more power, but now i expect it to break way sooner.

Re: is my columbia really that slow?

Hey Josh are you butthurt cause your moped sucks?

Re: is my columbia really that slow?

Slow down and live, its a fucking moped! Actually you should be able to mod that bike to hit 35mph pretty easy without a kit. Get a pipe, a nice free-flowing air filter, mild porting, and a re-jet. I wouldn't bother with a kit because the clutch is barely good enough to handle stock power.
