Answerjust take of the whole exhaust inlcluding the head which is the pipe leading to the engine, take that all of. your bike will be loud as maybe even to load but it will definently give your bike more power.

DO NOT DO THIS!!!!! especially on a 2 stroke engine! this will bend your rods and possibly ruin your whole engine!!!!

How do you make a pocket bike faster?

take parts off that u dont need to make the pocket bike go faster LOOSE SOME WEIGHT OR BUY PERFORMANCE PARTS remove the muffler, remove plastic pieces that are not needed, bore out the cylinders and get bigger pistons, swap sprockets or get a smaller rear sprocket. (this will make it slower off the line but significantly increase top speed. just like a mountain bike in low gear)


How do a bore kit make your bike faster?

A bore kit does not make a bike faster. It makes the engine more powerful if you want to go faster you must work on gear ratios and or sprocket sizes.


Increase power on pocket bike?

Well, there are a few minor mods you can do to increase the power, but if you really want more power, I would recommend getting a bigger bike, like a 150 cc scooter. But for the pocket bike here are a few things you can do: 1. Buy a big bore kit. 2. re jet the carburetor, and upgrade the air intake and exhaust. 3. Change the gearing [higher ratio=faster speed, less acceleration, lower= more power less speed. 4. Possibly fit a bigger motor in [if you are good with welding and machinery. 5. Find some sort of multi ratio transmission, like a CVT or 3 speed gearbox that will fit. Over all, getting a bigger bike is the best way, but hopefully these upgrades will help.

How can you make a 49cc Yamaha razz faster?

The Razz unfortunately doesn't offer much in the performance modification department. You can however get a 70cc kit from an early model Zuma to work but you need all the intake parts from said Zuma. With a Zuma big bore kit you will need a larger carburetor and either a Zuma factory exhaust or an aftermarket exhaust. Some modification to the exhaust may be needed. The easiest thing to do to add a little more top end speed is to put slightly bigger tires on your scooter. Stock size is 2.5 x 10, you would want 3.0 x 10.
