Pullstart Engine for MBX7

[ramdrive]

Hi All,

I have been given a used MBX7 and would like to use it as a basher at my local bmx track.

I need an engine for it but I would like a pullstart engine as I do not fancy humping a start box to my bashing area.

So the question is what are my options for a pullstart engine in the MBX7?

Thanks in advance.
