    Default Heelclicker clutching help, Mr Viper or someone

    I have a 97 venture 500 (LC) and I am experimenting with Heelclickers on that thing
    The set up is:

    5,2 gram at heel
    0 in center
    5 gram in tip

    White 4 stroke spring

    Secondary
    Yamaha green spring wrapped @60 and a straight 43 helix.

    The problem is that about 3/4 throttle it gets like 7500 rpm but at full it only gets 7400-7450. How do I correct this?

    less tip weight. try 4 grams in the tip or the red heelclicker spring.

    I can try less tip weight but won't that make the midrange overrev worse? The red spring is too stiff for the 500 engine to compress I think.

    the heel clickers we use in a sx venture have no screws in the middle at all. taking tip weight out should let hit the peak rpm of 7800 on that sled. i had an sxr500 that i clutched and i did have to fine tune it a bit to run right.

    Tightened the green spring to 80 deg, it won't fall flat on it's face on top end, but it overrevs to 8050 rpm. I guess I will have to screw on the nuts on the other side of the weight/bolt.

    looks to me from your description, its barely too steep of a finish angle and its actually trying to backshift slightly forcing the primary to fight the sec. clutch. I think my first move would be to try a helix with a 41 finish angle in it and go back to your previous sec spring twist, retest.

    tightening up the sec spring will raise rpm but it will make the efficiency drop down and take topend mph away.

    Didn't help any with a 41 deg spring. Still loses top end rpm, unless wrapped @ 80 deg.

    then go 39, it should climb rpm with shallower finish .

    or add a shim to primary spring, white is like 300, you might need 310 or so. red is 360, gray is 330.

    It will overrev too much with a 39. Maybe I'm using the wrong secondary spring? Is the green too stiff? Because 39 and green @60 will overrev, but if I remember correctly, not cause the rpm drop on top end.
    41 or 43 will cause it to lose rpm unless wrapped really tight. Can you add a shim to the primary spring? I think I read in the instructions that you shouldn't at least with a red or gray.

    then add a washer to the tip if overev on top with 39 if it doesn't fall back that tells me the 43 is too steep on the finish angle. nothing wrong with green but you might try a red dot sec. spring and see if it runs better. I use the red in the vipers, works well and gives very nice topend. you will have to go with more torsion on a weaker spring but it will yield better topend.

    once you find your paramaeters you can play with a multi angle like a 43/39, 44/40,etc. should give you the best of both worlds.
