razors getting a briggs the big one might get a 125 110 or the big bore tiny engine you have linked

I'd put a 125 on the big one (if it'll fit), use the engine I linked on the razor, and use the briggs on a kart. Maybe the one in background of the pic on post 1 (I have a good eye... the other got hit by a football).

I said what i said lol

I still think that bike would handle like a brick with that engine. Also, is that engine governed or ungoverned, either way the pocket bike engine will rev higher, without performance parts (that one is rated at 2.6 hp @ 7000 rpm). So, I remember you said the flatheads power somewhere, but I don't remember what it was.

Also, you need a new exhaust pipe, unless you plan on using that one as a seat.

This is a 5hp briggs with a slide carb, straight pipe, and no governor.

Oh it would definitely handle like a brick. How are you going to re-do the top frame rail? And how high'll she rev?

With those mods?
~5500 RPM.

I was planning to see how it feels before i remake frame bits but i already have to make a new seat mount because as you see it basically doesnt exist. Also this green briggs has many problems including a very nasty cylinder wall and it was not taken care of so if it blows up oh well. i probably will chicken out half throttle anyway.
