Derrickc14 Posted September 10, 2015 Author Report Share Posted September 10, 2015 It's not coming on to the band smooth. It's loading up or something. Just wanted suggestions on what you guys thought. I'm thinking the needle is to rich. Was going to drop it to the middle clip. Maybe even drop the pilot. The bottom end seems weak for this setup. Maybe raise my compression will help. Im prettysure it's at 135+-. Going to test it tonight. You think that will help also? I'm not sure Quote Link to comment Share on other sites More sharing options...
mike0chek Posted September 12, 2015 Report Share Posted September 12, 2015 change one thing at a time when tuning so you dont over complicate things 1 Quote Link to comment Share on other sites More sharing options...
RollinRhino Posted September 13, 2015 Report Share Posted September 13, 2015 If it is surging as it is trying to build power start with the needle settings. Quote Link to comment Share on other sites More sharing options...
Derrickc14 Posted September 13, 2015 Author Report Share Posted September 13, 2015 I wouldn't say it's surging. Kind like a rich studder then hits. Struggles to get on the pipe. I'm dropping my cel needle to the middle clip. Putting a 48 pilot in. My compression is 148 right 150psi left. Quote Link to comment Share on other sites More sharing options...

rjdgriff Posted September 18, 2015 Report Share Posted September 18, 2015 My serval liked the middle with the 35pwks at 1100' Quote Link to comment Share on other sites More sharing options...
Derrickc14 Posted September 18, 2015 Author Report Share Posted September 18, 2015 I'm at the middle clip now and I put the 48 pilots in at a 1.5 out. It starts without the choke. As far as I know, that means I should put in 45 pilots and my pilots should be perfect????. 300ft Quote Link to comment Share on other sites More sharing options...
rjdgriff Posted September 19, 2015 Report Share Posted September 19, 2015 I believe I had 45 pilots in mine. I think lol and maybe a 158 main if I remember correctly Quote Link to comment Share on other sites More sharing options...
Derrickc14 Posted September 19, 2015 Author Report Share Posted September 19, 2015 Yea I plug chopped my bike with 9es plugs cause Jeff told me to but everyone says it's too cold for my set up and my plug chop left only half a dark ring around it so someone said the plug is too cold anyway. I'm going back to Br8es and going to redo my chop 1 Quote Link to comment Share on other sites More sharing options...
