hi guys,

im looking to get my 1st .21 engine this weekend and was pretty keen on the Go.21 Gen 5 R spec 3 port. it will be used for race/practice only.

i was wondering if there were any break in tips i need to know and if you know any tricks or methods to make life easier?

i've been trying to decide on exhausts and it looks like im gonna get the Redline for it, i was also tossing up between the JP1 and Go 3 chamber. have any of you used the Redline pipe before?
