the pipe you have now will probably work just fine on the new motor. a friend of mine runs a stock crf70 pipe on his lifan 140. It chokes the flow some I'm sure, but still runs fine and is quiet as can be.
Piranha 140cc Engine
im planning to buy a Piranha 140cc Engine that comes with a carb.
i already have a 100cc engine i know that my hedder will dont fit for this motor, but i have a very quiet muffler thats on it. i would like to cut it off the hedder, and buy a header for the Piranha and weld the muffler to the new hedder. can i do this? also what size hedder should i get for the 140cc and where could i buy it????
i have a mini chopper with a dirt bike motor ill try to post pics later
