GRM Performance's Centre Melbourne experienced and qualified performance mechanics can deliver more power to your V-Twin motorcycle. The first step in higher performance from your V-Twin is our stage 1 performance kit below.

These components are the essential upgrades needed before completing any other performance work to your V Twin motorcycle

Our Stage 1 V-Twin performance kit listed below is for those that current have a stock or midly modified engine, if you already have other modifications, please talk to us about the suitablity of the stage 1 performance upgrades that will give you true results. With the endless number of performance upgrades you can make to your V-Twin it is important to choose the most suitable options that will deliver the best results for your specific make and model.

At GRM Performance Centre we can advise on what performance enhancements will give you the best results for your V-Twin. GRM Performance Centre Melbourne Stage 1 upgrades specifically suited to V-Twin motorcycles consists of the following:

There is no greater beginning upgrade you can make than a Stage 1 which is entirely a add-on procedure to your current engine.

These upgrades can be installed individually but the true performance increase on your V-Twin will only come to being once all three of these components are completed.

V-Twin Re Jetted Carburetor or Remapped EFI

With free air in take and exhaust out your V-Twin engine now has the setting to provide a more stable and effective fuel mixture. Standard carburetors and EFI's are not designed with the performance potential your engine now has.

V-Twin Carburetor models

Your carburetor or EFI will need to be corrected to compensate for how differently the engine now breathes. On a carbureted V-Twin engine this means re jetting to allow more air and fuel into the engine in a controlled and managed manner.

As part of your stage 1 kit we install new carburetor jets designed specifically for your make and model of motorcycle, offering true performance fuel management and increased engine efficiency.

V-Twin EFI models (Electronic Fuel Injection models)

V-Twin EFI models (Electronic Fuel Injection models) are another story. Fuel injected models use a preprogrammed mapped computer to instruct how much fuel is to be delivered.

Since you have changed the way the engine breaths, those instructions will not supply the proper stable fuel mixture or give you the best out of the performance potential your engine now has. We recommend Power Commander or Power Vision systems which are the most reputable and proven on V-Twin engines.

Both Power Commander & Power Vision System can be programmed or "re-mapped" to deliver the perfect fuel mix to air intake and exhaust ratio at any RPM or riding condition - but this can only be achieved by programming the unit on a Dyno Jet dyno machine designed to run your engine through every riding scenario and map the computer with the fuel mix instructions.

GRM Performance Centre is one of the very few fully authorized and certified Power Commander Dyno Center, using the latest in Power Commander Dyno equipment installed in a sealed dyno room.

GRM Performance - formerly Ghostriders, can, as part of your stage 1 performance enhancement, program your engine at peak performance no matter what EFI model of V-Twin motorcycle you ride.

V-Twin Free breathing air cleaners and intakes

V-Twin free breathing air cleaners and intakes allow more air into your engine for ignition giving the engine as much free air as it needs rather than being restricted as the stock air intakes are designed. This is the simplest performance upgrade for your V-Twin engine.

Depending on your budget this ranges from changing the air cleaner to a high air flow model to a a new high air flow air intake full intake assembly such as from K&N, Kuryakyn, Performance Machine and more.

Each option offers different design looks, and shapes for better air flow. You don’t have to spend a fortune but you should select a design that will fit your bike well, blends into your overall theme and is of a quality brand. Some of the models available for you to choose from allow you to use your stock cover to keep your orginal look and design.

V-Twin Free Breathing Exhaust

Air intake is only half of the equation of increased airflow to your engine. Air exhaust flow is the other half of the equation. If your V-Twin engine can get all the air it can use, this then needs to be expelled just as easily or your engine will continue to struggle to run at it's peak performance.

As with the free breathing air cleaners and air intakes this upgrade can be simple or extreme. Many choose to keep their stock pipes and go with slip-on mufflers. These are easy to install, maintain a stock look, and add plenty of performance.

Popular slip-on models include HD Screamin’ Eagle II, Vance and Hines, Freedom, and Cobra to name a few.

These brands also offer complete exhaust replacements that are specifically designed to give full unrestricted exhaust air flow, a custom look to your V-Twin motorcycle & deliver a custom sound as well.

A free breathing exhaust for your V-Twin is a must have performance upgrade to achieve more performance and allow your engine to run unrestricted.
