Bought this sled with bender can, bender traction bar things, bender clutching, vforce reeds... 8,200 rpm......i installed bender tripple pipes.. Now its at 86-8700rpm... Clutches and belt are quite warm to the touch... Not burn you but petty darn warm...... I know it needs to spin 88-9000rpm... It has solid black secondary spring, bender helix, and black with a blue smudge primary.... engages at 4000 rpm... I'm outrunning a 98 srx700 bottom to top by about 1-2 sleds consistently ... I put sharpy marks down both clutches... Primary has about a 1/4 inch line left up top... Secondary is same but of coarse line is left down bottom... any input greatly appriciated
