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
