What would the advantage to these fuel injected engines be? I know that some of the reason that it took KTM and other dirtbike manufacturers so long to bring fuel injection to their world was because it’s more complicated, and fuel injection doesn’t actually make more performance. Conversely, it adds weight and complexity to an otherwise straightforward setup.
There are a couple of benefits that one article I found mentioned. For one, they provide just the right amount of fuel at all times, which can allow the engine to idle, but in a kart application there are moments where we need more fuel for the upcoming situation. A furl injection system will not always be able to provide in these scenarios. Are these benefits more desirable than both the performance that will be lost and the cost that is being added?
Here’s the article I stole just about all my info from: http://motocrossactionmag.com/news/ask-the-mxperts-whats-holding-up-fuel-injected-two-stroke
