Its a 4 speed or 5 Speed

If its a 4 speed get a 5 speed Block piston,
port it,
out 125 carb and bigger jet
change the air filter
make sure that crank and connecting rode are perfect
change the clutch plate
change the sporckating,
if you want more power change the gearbox make it 5 speed

Take it to a decent boring shop and get it ported.

You might need to upjet after that... and the bike will fly.

Simple as that.

Or buy a proton off the shelf-they work pretty decently.

Dude, pls dont forget front disc brakes though they do not contribute anything to the punch in power that you want, but its for your safety as RXZ is a light bike and can really make you fly.
As for the power, pdev29 has good suggestions.

all the best!

So many tricks to make the RX series move faster. Just search on the forum. You have plenty of threads here or PM me or the others.

MODS, please close this thread

2 stroke tuning is a lot more difficult than just porting the engine and changing the transmission or sprocketting.

Its best done in stages. Stage 1, Stage 2 and stage 3. There can be a lot more stages depending on the tuner and as to how far he wants to go with each stage.

First decide on what you want man. "I want max power" is not descriptive enough. Do you want max power for city riding or are you doing this to try and touch some top speeds? When do you want the power band to start? How wide do you want the power band to be? (There are limitations. You can't expect your power band to start at 1k RPM and end at 9k RPM). How late do you want the power band to come in? You also gotta understand more power also means lesser reliability. You gotta decide on how much is too much for you. There are drag bikes whose engine life is measured in a few thousand kms or even a few hours of racing.

There are a lot more parameters than the ones that i've outlined above. I would suggest the 5 speed barrel for power(that again is if you want outright power. If you want more torque and a peppy bike for city riding, a better option would be the 4 speed barrell.) A 5 speed transmission is good again it depends on how you want your bike. There are guys who have converted 5 speeds to 4 speeds 'cos it suits their style of riding.

My advice, first make up your mind as to what exactly you want. Then start off towards that with first blue printing the engine (Stage 1 port). This is not called "porting" again 'cos all your doing is just getting the engine to the exact specs that the company outlines to get the factory mentioned output. Mass production will have effects like casting flaws, wrong squish band width, a crank that is off. All in all its correcting all the wrongs that are there in the engine. This is tedious work and is not going to blow you away with performance, but its a good foundation to start off with for the other stages of porting. Take it slow 'cos it ain't like a 4 stroke the power will be sudden and you have to get used to it.

Ask around, get a few opinions from 2 stroke riders with ported bikes as to who they would suggest for your port jobs. Your not going to touch top speeds with just one port job.(Maybe you would, but your bike might not be the best tuned or closest to perfection). You have to keep improving on the previous set up.

If you need anymore info. just let us know, there are a lot of people who would be willing to help.


All this research and hard work gone into accumulating information and still no money to start work on my RXZ.

HONDA....if you want your Yamaha to fly then go the way Cockroach has suggested. That is the only way to do it. Its a lot of hard work but if you persevere you will get the results.

Deeghi a bigger carb means a carb which has a bigger venturi. Carbs come in sizes measured in mm. I think a RXZ uses a VM22. 22 stands for 22 mm.
