BlueRock Posted February 26, 2019 Report Share Posted February 26, 2019 (edited) Hi, Does anyone know what compression head the 2017 TXT Racing 300cc E4 runs as standard? I'm sure I read somewhere that the E4 was designed for the US market and had a high compression head as standard, but could be wrong... Reason I ask is that if it is a high compression head as standard, I'm thinking of changing to one of the S3 lower compression inserts, but don't want to change it without knowing what head the bike has first. Any help would be appreciated Edited February 26, 2019 by BlueRock Quote Link to comment Share on other sites More sharing options...
bumpy_ltd Posted February 26, 2019 Report Share Posted February 26, 2019 Pretty sure it is standard. However the S3 Inserts wont fit the standard head anymore (GG changed them) so you will need to buy the S3 outer as well. Quote Link to comment Share on other sites More sharing options...
