Questions & Answers

  • Do you have a picture of the kit installed on a VM38? Where is the bottom fuel hole drilled ?

    We don't have any photos, but if you do an internet search for "vm38 mikuni power jet" some low quality, vintage photos show the general idea. Unfortunately, I have not run across any that show the fuel feed. There are no provisions on the VM38 float bowl, so you will need to get somewhat creative for that carb.
