      It depends where you are racing.  Long straights and big turns longer flex. Short straights tight turns shorter flex. Gear for the bottom pipe for the top. I would put the 10 degree mount back on for better cooling.

      It’s an RLV but not sure which one it is exactly. Went to their web site and can’t decipher from the pics which one i have. Sent a pic to a well known racer and he thinks it’s an old A4 whatever that is.

      When i got the kart it had a piece about 7″ long between the header and the actual pipe.

      Guess I’ll just start there and adjust!

      anyone care to share gearing for Roebling Road

      If it’s an A4 then the measurement from the face of the piston to the end of the connecting tube (flex) should be 7 1/2 to 8 inches. Tune from there.
