What is involved with installing a kit?

Installation of one of our supercharger kits is relatively straight forwards and can be easily accomplished by anyone who has access to basic tools and is familiar with basic air-cooled maintenance such as setting your points and timing and adjusting your valves.

Installation is definitely easier with the engine removed but this is not absolutely necessary.


Physical installation

Basic installation involves the following steps

  • Swap crank pulley
  • Loosen fan shroud and remove existing manifold
  • Install new manifold
  • Remove fuel pump
  • Install supercharger and stand
  • Connect throttle cable
  • Install electric fuel pump
  • Modify distributor.
  • Tune and drive.


Tuning

Tuning the carburettor is a little more involved, but is easily achievable using our step-by-step guide in the documentation provided with each kit.

If you've purchased one of our carburettors with the kit, then it will be set up with a baseline tune. This is enough to get your engine running, but it WILL still need to be tuned to dial in and optimise the tune for YOUR engine. The step-by-step procedure walks you through the process, but it requires that you have access to an O2 sensor. 

O2 sensors are now affordably cheap and should be considered one of the tools required for the job. It's $50 well spent. Borrow one from your mates or hire one for the day, it will will help you save 10 x that at the dyno. Not only do we walk you through the process in the documentation, but we also provide advice via our help-desk if you get stuck. 

Whilst tuning carburettors might seem like voodoo or black magic, as long as you follow the steps described in the documentation, it is absolutely achievable. We've tried really hard to make this accessible to everyone. After all, having to throw a bunch of money at the local dyno is a cost that can be avoided if you know what you are doing, and our documentation and support provides you with the knowledge you need. It's really not that hard. All you need is half a clue and a bit of patience.


Guessing

You can of course elect to ignore our instructions and simply take a wild stab in the dark, or even better, use the recommendations of armchair experts on Facebook. But it's not really something to be guessed. All engines are different, and they all require a different tune. There is no one-size-fits-all jetting recipe, no matter what the keyboard warriors tell you. 

The biggest single source of issues with tuning and setup is people NOT following our instructions. Using internet jetting recipes or just swapping out jets without actually measuring the O2 level. If you're not validating the changes that you are making by measuring the O2, then you are guessing. Guessing voids our warrantees and we absolutely guarantee that it won't get you where you need to be. It will only get you frustrated.

If you do not want to follow our tuning guide (or pay someone else who knows what they are doing), please do not buy our products. You're not going to be happy with the result, as it will not work properly or worse may damage your engine.  You will also not be happy when we withdraw support (please read our T&C's). The one thing that I have learned after doing this for all these years is that arguing with idiots on the internet is a battle you will never win. They will drag you down to their level and beat you with experience.

So if this sounds like you, please go buy one of our competitors products instead, but be absolutely sure to send us a postcard and let us know. Because it makes us immeasurably happy to know that you are wasting their time instead of ours. ;)
