Whitedog-
I'm sure you've already thought about this, but wouldn't you rather try out the 47 gram weights at 47 grams before grinding them down? You can always remove weight, but it's hard to put it back on!

Yea, Im definately gona try the weights before I start to cut em. But I dont think 47 is going to do it. Because the C weights after I tucked the heel down were roughly 47 and I could only get 8200 out of it. Its been a strugle to get it to rev this high, 58s produced 7000 - 53s produced 7300- and 48s produced 8200
Baxy has a good point, but I really dont think this pipe makes any low end grunt. I mean this thing was sad with S58s and the almond spring. Realy sad.
The only thing I can figure is the engine needs to engage high, with this pipe, so it can be closer to the sweet spot. I dont know how else to do it, If I run a less load spring then Ill have to run even lighter weights.
Im open for any and ALL sugestions
Brent

Hmmm, thanks Ced. Then I could possibly run some heavier weights. I read somthing in the "clutch bible" about having too light of a weight, for a heavy spring, possibly smoking the belt in the first few feet of a race.
Anybody have one?

a heel clicker might be what your looking for

you definatly need a stiff spring to control your shift out and high RPM
but with the lighter weights you end up with a wicked high engagement
but with a looser spring you will shift out too soon and kill the power because your not producing any torque

so the heel clicker will allow you to run a heavy weight at engagement and lower engagenemt RPM but as it shifts out and the wirght becomes lighter you will have the RPM you desire still using the stiff spring

so something like a 45gram heel clicker with 5 grams in the heel
and the maroon spring might get you pretty close
lower the engagement to about 5000 to 5200 ish

overdrive belt mean a shorter belt by half a inch to get more squeezing
while using lower gearing and heavier weight.
the best suited for you task will be the thundershift cam arm weight
(adjustable weights) or the heel clicker,very cheap and easy to make tune changes to get the rpm you're looking for.
i prefer the thundershift weight wich i use them for many years on sled
and 2 seasons on the quad yet.
as baxy you told you above you'll be able to get the lowered engagement
you need and still maintain a progressive shift and loading the engine
all across the rpm range with any flat spots.
