Do you have the need for speed?

Well then get another scooter... the deristriction guides out there are for newer machines that are more restricted, besides Iowa models, Sprees are not very restricted. There are no speed modifications that you should do to any year spree. The best suggestion I have is to de-carbon the combustion chamber and muffler, then clean your air filter. If you do any modification at all your gas consumption goes up. Making your half gallon gas tank go empty really fast.

*Do not try this*
You still can upgrade your scooter by getting a bigger piston, rebore your cylinder, and getting a bigger carburetor. But I wouldn’t undertake those procedures unless you have:
1. A lot of money to burn (revamping the engine would cost more than the spree itself)
2. Vast knowledge of engines
3. The exact right tools for the job
4. A death wish (you’ll be going extremely faster than the wheels/brakes/transmission were made for)

Noiseguy's hints to hop up your spree.
(Try at your own risk, I seriously do NOT recomend any modifications of any kind to your Spree)

"If you really feel spunky, want to get the most out of your ped and you have about 40-50 bucks to spend and 4 hours of free time here is what you do.

1. Remove the head and have about 60 thousandths shaved off. 20 bucks labor and 6 bucks for a new head gasket. This will increase your compression for more power

2. Take a dremel to the intake manifold and open up the restriction, you will see it when you remove the manifold. This will increase air flow, more top end power

3. File about 1/16 inch off the front inside pulley half on the belt drive. This will slightly increase the drive ratio for a higher top end

4. Buy a size 70 main jet and install it in the carburetor costs about 6-10 bucks at your local Honda dealer. You will need this if go to an after market air filter assembly to insure proper air/fuel ratio

5. Buy the chrome topped cotton filter element K&N oil breather cap for a Chevy v-8. It costs about 12 bucks and it makes a perfect after market air filter. It fits right on the rubber tube that goes to the carburetor. You will have to remove some off the old air filter assembly though. This combined with the jet gives you more top end power and RPMs.

6. Drill out the exhaust. That relieves some back pressure for more available power."

If you question why I would not do this, reffer to number 4 of the first *Do not try this*
