2cycle Pipe ID ???

[Phiddy]

There is a discussion below about Mayko pipes. Anybody an expert on RLV?
I got a pipe that I thought was an "A2" but it turns out I have another A2 and it looks totally different. Is there such a thing as a triangle or a delta symbol that was used?
Another question, can someone explain the difference from the "A" 1,2,3,4 vs. the "G"1,2,3,4? I have guessed the higher the number is a narrower and higher rpm powerband?
I also have a couple marked "3FD" ????
Thanks! 50

The 35 fd is for 135 cc and open . Same thing it comes in different variations .

Wasn't the RLV "delta" series pipes the predecessor to the "A" series pipes? And then, the "G" & "L" series pipes after them?

 

[shiftyag]

pretty sure it was the G, then Delta, then the shorter flex A, and then L

Delta, G, A, then L. The A pipe/header was the big leap forward. A and L pipes are the same but with different headers. Yes the lower the number the broader the power band.
