Hello

Yes. i asked the same question about 5 months ago...Vellum and the like will confirm that their is indeed enough room for a 2 stroke pipe, ( ie. 140 RX ) but the guys here will most likely strongly recommend you go for a powerful 4 stroke as power. I`m still not sold on the 4 stroke thing myself, ( I`m still in luv with the 140 FI ) but with that said they must use 4 strokes in the world championships for a reason right!!
Sometimes i wonder how CPLR or Quique would have gone with a 2 stroke!!! ( food for thought huh? )

Regards
