Happy New year to everyone in the forums helping out us MiniBike enthusiast,
For my first engine build I have decided to go with a Briggs 5hp Flathead from an industrial fan. I am sure there are a couple of threads on flathead builds on this forum already. Although all are great, I still have unanswered questions.
I should start with what I am trying to accomplish. I am trying to maximize the potential of the engine without having to use a hand held starter, as well as run high octane fuel. My questions are concentrated near what parts match together that work in unison. From what I am understanding the raptor block is a little different from the standard 5hp briggs. The only noticeable difference that I see is the extra bolt hole for the aftermarket carbs that require fuel pumps. I am deciding to stick the the original style carburetor, so that should not be a problem.
If I were to go with an open/limited cam what set of lifters and valve springs should be looking for? The end result of my build is to be somewhere around 12-15hp.
Any advice or links to other threads would be great,
