No. The exhaust stroke becomes the intake stroke sucking in air through the exhaust tubbing. The combustion stroke becomes the compression stroke. The injector is cam driven and fires what used to be just before top dead center, but now fires just after top dead center (and retards from there with more RPM's since timing is centrifugally driven.) The compression stroke is now the combustion stroke. The intake valve opens at the end of the what is now combustion stroke and becomes the exhaust valve. Now starts what used to be the intake stroke but it's now the exhaust stroke as it pushes exhaust through the intake manifold.
