When GASGAS introduced the VF3 reedvalve on their bikes it turned out to be very disappointing compared to the VF2 set in low tension mode. I took my VF3 out after three rides and replaced it with my old VF2.
The VF2 in low tension mode gives the GG250/300 smooth low end power without sacrificing anything on top. I really disliked the way the VF3 made my EC300 run.
