Might go grass dragging soon, who's got the best set-up? Clutching, gearing, jetting?? Heel clickers? 8bu-00s? 2001 SRX700 -- 500-660ft whatever COSDRA is?

-40-10Y Heel Clickers with an engagement notch ground in them, engagement should be around 4900 rpm.
-Red Heel Clicker spring
-15.6mm rollers
-6-grams heel
-0-mid
-7-grams tip
-45/41 advant-edge helix
-silver secondary spring @ 70-90* (depending on conditions)
-20/39 gearing
-K&N Air Filters RU-2750
-Rear spring set with 1" of thread showing
-FRA in the stiffest setting
-Transfer rods adjusted for traction (preferred less than 1/16" of gap on top side and locked solid when on good traction)
-Limiter Straps set as needed (you want 2-3" of ski lift off the line and skis barely in the air going down the track).
-Front spring in the rear suspension tightened to the max

Setup from the 2nd place SRX Hay Days 2000 and NSRA Tri-State Triple Crown winner in 2001 (won events at Princeton MN, Grayslake IL, and Wausau WI).
 
Nothing for heavy hitters. Tried them and they were slower, threw the notes away after that. If I still had a SRX setup for grass I'd try the new Super Tips, I think you could be even faster then. As far as the 56/44 you're gonna need less heel weight then.
 
ALLAN, YOU HAVE ALWAYS TALKED HIGHLY OF THESE HEEL CLICKERS. I KNOW YOU TRYED 8BU-00,s. NOW LET ME ASK YA TWO QUESTIONS, IS THAT A YAMAHA SILVER SECONDARY SPRING YOU USED AND I ASSUME THERE ARE THREE TUNEING HOLES ON THESE WEIGHTS BECAUSE YOUR LEAVEING MIDDLE EMPTIE. SEEMS YOU COULD RUN MORE HELIX THAN A 45-41. SOONER OR LATTER I HAVE TO TRY THIS IN MY 2000 SRX. 696 TOLD ME THIS WORKS NICE TOO, HELL I WOULD LIKE TO TRY THEM IN A 800 VMAX. WHAT YA GOT YOU CAN SELL !! 3:16 (tony)
 
Tony, the silver is just a factory Yamaha secondary spring. The heel clicker has an adjustment point in the "heel" of the weight, then one in the middle and one on the tip of the weight where you can add or remove fasteners. The 8BU's are also a nice weight and work well, I just hated pounding rivets in and out to make adjustments to the weights! The 45-41 Advant-Edge helix will shift like a 49/45 or a 50/45 when comparing it to a Micro Belmont, Maxx Perf, Bender, Dalton, etc. Let me do some digging through the shop bins. I know I have some heel clicker sets around yet that I'll let go cheap.
 
Clutch temp's were in the 120-130 range if memory serves me correctly. On today's 4-strokes we have clutch temps down to 100-110* using the Super Tip weights. I know we could've went faster with the Super Tip weights in our 01 SRX, just don't have the sled anymore!
 
What makes them better you think? Is it the profile? Have you tried the 40-20 heelclickers? Just curious as to how they work.

yea everytime i have used clickers i have noticed significantly elevated clutch temperatures no matter what you do. Too much squeeze force maybe to get the fast upshift creating friction being lost as heat energy?
 
The heel mass of the weight, the location of tuning spots on the weight, and slight differences in the profile = better acceleration, top end, and back shifting in my testing.
