oldskool Posted March 19, 2013 Author Report Posted March 19, 2013 the way you tell the sb from the bb is by measuring the end of the expansion chamber( not the stinger) if it measures roughly 1 inch they are small bore, if the measure 1 1/8 inch they are big bore, Got this info straight from CPI Thanks for the info. 2strokeshees, do these pipes look familiar?

ban565 Posted March 19, 2013 Report Posted March 19, 2013 small bores are 7/8 on the pipes. Big bores are 1 inch. both are id Quote

Most shearers suck, and a lot of the rockets suck as well to fit up. Which Rockets? I have owned three sets and installed at least two others and they have all fit perfectly. Are you talking about Rockets or R2? Quote
