i have an 01' 400ex with a PC T-4 and an outerwear over a K&N (elevation about 700 ft, about 70 degrees outside). i just modified my airbox lid like the EHS lids (bolting an outerwear over a hole in the lid).
anyway, i had been running a 158 main and a 42 pilot (choke was removed). it seemed to be running pretty good when the lid was on, but now that i cut most of the top out it seems to have lost some torque. it feels like it gained quite a bit of topend. so if i lost low-mid power and gained topend what should i do. do i move the clip on the needle?
in the old dirtwheels article they tested a T-4 with a K&N and an open airbox under relatively the same conditions (a few hundred feet lower elevation) and said a 155 was about perfect. any ideas?
