Derrickc14 Posted December 30, 2014 Report Share Posted December 30, 2014 Ok so I'm soon making the change from t5 to Small bore cpi pipes. Just did some research on here and right now the way it sits with my dune port, .030 milled head, v3reeds and +4timing, CPI's are the way to go plus I'm going with coolhead 19 cc domes to get up to 180psi. What type of jetting changes am I looking at from going to cpi pipes and 19cc domes? Some post say you don't need to touch it. Some say just move the needle one position but didn't state up or down. I just want a good idea what I'm going to be changing. Right now with the milled head I'm at stock pilot with 330mains. Some people said to move the needle to the 4th position etc etc. I seen so many different things but they didn't seem to have the mods I have done already so that's why I need expert advice from a goorue. Thanks in advance Quote Link to comment Share on other sites More sharing options...

Derrickc14 Posted December 31, 2014 Author Report Share Posted December 31, 2014 Yea I'll be running c16. I can't seem to find any SB CPI's. I refuse to spend 700. Might go with the poor mans CPI's but they will rust my first ride. Quote Link to comment Share on other sites More sharing options...

Might go with the poor mans CPI's but they will rust my first ride.I would re think the C16. That's just paying more for fuel you probably might not need. Look in to the C12 as well as their newer VP113. It's oxygenated but carries a tinge more octane then the C12. The vp113 is in most of my stuff and I love the results.

Adam Premo Posted January 3, 2015 Report Share Posted January 3, 2015 When I got it there was 220 in it will that hurt,or do I just mix rich? Quote Link to comment Share on other sites More sharing options...
O/CbansheeRider Posted January 3, 2015 Report Share Posted January 3, 2015 Changing the mix is the fuel/oil ratio. Changing jetting is air/fuel ratio. To different things. You need to change jets not mix! Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
