Power_Man Posted March 25, 2013 Report Share Posted March 25, 2013 So I have been running my machine for a while. Closed air box with K&N filter and T5 pipes. Running. 290 jets for about 4*c weather. Goes good till about just past 3/4 throttle. Then falls flat. What do I need to change. ? Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted March 25, 2013 Report Share Posted March 25, 2013 Is your air filter clean? Have you checked the plugs? Quote Link to comment Share on other sites More sharing options...
Power_Man Posted March 25, 2013 Author Report Share Posted March 25, 2013 I haven't done a plug chop, but after a ride I pull em and they are a brown/black colour. I need to grab another set of plugs so I can do a chop. Will I kill throttle when as its falling on its face or just before? I just got the filter, and the guy I bought it from said it was just cleaned and oiled. Quote Link to comment Share on other sites More sharing options...
notsed Posted March 26, 2013 Report Share Posted March 26, 2013 could be to much oil on the filter, did you change anything else besides the filter? Quote Link to comment Share on other sites More sharing options...
Vicstuff Posted March 26, 2013 Report Share Posted March 26, 2013 Filter is clean and pretty positive I didn't over oil its definitely not the first filter I've cleaned/oiled lol Sent from my HTC_Amaze_4G using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...

Power_Man Posted March 29, 2013 Author Report Share Posted March 29, 2013 Okay. I'll take lid off and go for rip. The previous owner has BKR6E plugs in it. So I had a set of BR9ES new in box. (I know should be 8's). But thought plugs should be changed. I went for a rip with the new plugs and killed throttle at CLOSE to WOT. AND THEY look like this. First picture with flash. Second no flash. Quote Link to comment Share on other sites More sharing options...
Power_Man Posted March 29, 2013 Author Report Share Posted March 29, 2013 HOLY FUCK! night and day difference. Took air box off and runs like a banshee! (Pun intended! Lol) So with lid off, do I need a re-jet? Quote Link to comment Share on other sites More sharing options...
Power_Man Posted March 29, 2013 Author Report Share Posted March 29, 2013 Cant edit, but i took the LID off airbox, not the whole airbox. Quote Link to comment Share on other sites More sharing options...

coryv4 Posted April 2, 2013 Report Share Posted April 2, 2013 if you want to continue running it with the lid so you dont get water and shit drop the main 1 or 2 sizes and see how it runs. Quote Link to comment Share on other sites More sharing options...
