Post How should I modify my Zuma?
I have an 01 Zuma 50. It's bone stock and does around 40 mph. I want to mod my scooter to get more speed. The first thing I plan to do is derestrict it. Does anybody have a good how to video on that? After derestriction I don't know what to do. Looking for advice. I'm willing to spend a couple hundred bucks, but not much more than that. I'm willing to lose a bit of acceleration in order to gain speed. This will be a daily driver so it needs to be reliable. I don't care about legality (I'm willing to use a big bore kit, racing parts, etc.).

Congratualtions on your upgrade journey

Prebug
no variator wedding band to remove
Has a exhaust restriction washer only .
How to do it if you are keeping stock exhaust .
You just dremel out the the 2 welds and pop it out with a screwdriver it looks like a flat washer welded in exhaust pipe real close to the end that bolts up to the header.
Now when you put it back on to avoid air leaks I would put anew exhaust gasket in and use permatex goldto help seal it up .
Air leaks are deadly and cause you to run lean
Before you make that move you should have a couple sizes up in carburetor jets .
Other wise you may run lean and cook your scooter .
When i derestricted my Vino's this added about 4 mph top end and acceleration was much improved.

Or just by a new pipe that will match up to the eventual BBK your going to want to put on anyway.

How much money you want to spend and and how much ongoing tinkering do you want to do are 2 very big questions .

Race kits more money more ongoing work.
Sports Kits long life and less money .

I prefer the sport kit path myself and my winter project is upgrading my 2004 zuma with a just ordered malossi bbk I paired it with a wild lion exhaust.

I have had both expansion and standard looking street pipes
I prefer the wider power band and stealthiness of the street pipes .
The race expansion pipes are fun when you have them dialed in really let your engine scream

Scooter builds
This is my experience with sport kit set ups and the major expenses

Budget

Under 50 bucks
derestrict ehaust new gasket permatex and up jets for carb

150-250 bucks
a pipe or sport bbk
I lean toward bbk here if mechanically inclined and could only afford one .

350-500+
pipe and bbk and now you start upgrading parts of transmision and carb

You can go as far as you want it gets kind of addicting for each little extra improvement.

I just don't tell the wife how much i spend she likes the results we have the same agreement about her victoria's secret spending I like those results .
