if i change the spring tension in the secondary, how will it effect the performance? Have a f5 and the spring is green and in the middle hole. If i add tension to the spring what will happed and what will happen if i take tension away from it?
I am no clutching EXPERT, but I think I can help. The secondary controls upshift and backshift somewhat. Not as much as the primary. If you loosen up the spring the clutch will be able to open more easily. You may notice a slight rpm drop at lowend. It makes the motor work a bit harder. You will also lose a bit of backshift. On the other hand if you tighten up the spring you will have better backshift but the sled will rev more as the clutch upshifts. So in theory your sled will go faster in a straight line if you loosen the spring. The sled will handle the nasty twisties better if you tighten the spring. That green spring is a awesome backshifting spring. It is very stiff. Hopefully that helps.
On my f7 i maked off a spot and made 3 run's
99..99..101.I then went back and took a thick
shim out of the clutch and moved the spring back
one hole now in 2 hole...made 3 more run's
103..103,...104...this was on a road in a strait line
my rev never droped like i had hoped it would still
turning 8220 on max recall..want to get it done to
7900 or lower.
