Nightmare Posted August 4, 2013 Report Posted August 4, 2013 In that case you should hook better on a actual track. What size tires? Sent from my SGH-T679 using Tapatalk 2 Quote
Tedder Posted August 4, 2013 Report Posted August 4, 2013 You definetly need to pull arm weight from the lockup but the street is no place for a drag bike and your efforts would be a waste of time because that surface will never duplicate a properly prepped race track. Quote
10milmike Posted August 4, 2013 Author Report Posted August 4, 2013 20x10-10. U are right tedder. Just wanted to trying out. Sent from my DROID RAZR using Tapatalk 2 Quote

dozer Posted August 4, 2013 Report Posted August 4, 2013 Wouldnt change a thing until i made a few baseline passes at the track. Ive been on starting lines that are so sticky theyll pull your shoe off. On the street local guys use traction compounds or do a few burnouts to lay some rubber down. Also concrete or grooved concrete tracts up alil better than smooth pavement. Quote
10milmike Posted August 4, 2013 Author Report Posted August 4, 2013 Well I am going to go with Brian suggestion with stock springs and 15/19 grams on every other arm. And make adjustments from there. I am new to asphalt so this is a learning curve. Sent from my DROID RAZR using Tapatalk 2 Quote
sprinklerman Posted August 4, 2013 Report Posted August 4, 2013 Ok bike spins so bad out of the hole. I left the lock up same as if i was hillshooting. To much weight out of the hole. Think I am going to run only 4 stock springs and 16oz on three fingers and 19oz on the other three. I tried 4 stock springs and similar lockup weight and just pushed right through the clutch,,sounded like a CVT! haha I know they rest of our setups may be different ,but i assume by your name that you are running a 10mm Cub like me.

SlowerThanYou Posted August 4, 2013 Report Posted August 4, 2013 Well I am going to go with Brian suggestion with stock springs and 15/19 grams on every other arm. And make adjustments from there. I am new to asphalt so this is a learning curve. Sent from my DROID RAZR using Tapatalk 2 just 4 stock springs? interesting. I think there's some confusion on what I said. I recommended starting with 6 stock springs & you have the weight right. Even with that I recommended he should check the base pressure! I'm going to reemphasize what I have talked about in the Lock-out/Lock-up tuning thread. Just throwing springs in without base lining the pressure at the installed height is like a dog chasing it's tail. Now, I did talk about a 4 spring set-up & even a 3 spring. WARNING: Less isn't always better! There are many things you need to do to make this work. It's not for the inexperienced clutch tuner! Quote

My motor is a 10 mil cheetah. OK. Well I was talking about 4 stock and two HD springs not just 4 springs and two empty holes. Well I am going to run what I have Friday just take off some weight on the lockup but leave the springs the way they are. I will post my slips Friday night.

phunt Posted August 5, 2013 Report Posted August 5, 2013 Any time you start playing with spring pressure you need to check your base pressure , because when you start playing with springs you need to know your change. Baseline,baseline guys!!!!! Quote
sprinklerman Posted August 5, 2013 Report Posted August 5, 2013 I'm a little confused here, maybe it's because it's early in the morning! Let me start by saying the normal way or standard for weighing arm weights is using grams. I used a conversion calculator to do the math. Are you sure on 27 oz. on each finger? That's a butt load of weight, you are 5 oz. away from 2lbs of weight on each arm!!!!!! Something is amiss here. This post got me to thinking about excessive arm weight. I know the OP meant Grams,not Ozs,but what WOULD be considered excessive? Ive ran across a few guys running 15-20grams per arm (seems somewhat common) then some guys up into the 30+ grams per arm. At what point are you simply overloading the arms because of too light of a base pressure? ** If this needs to be moved to the "tuning " thread ,that's cool. 1 Quote
phunt Posted August 5, 2013 Report Posted August 5, 2013 Some guys put all that weight on the lockup because when its on the dyno its has to because of the load of the dyno. There is a guy I race with that runs 30 grams per arm, I don't have 30grams total on mine. Quote
10milmike Posted August 5, 2013 Author Report Posted August 5, 2013 Here is a pic of my bar we built. Are u guys running 3 bar or 4 bar? Sent from my DROID RAZR using Tapatalk 2 Quote
Nightmare Posted August 5, 2013 Report Posted August 5, 2013 3 bar here. Sent from my SGH-T679 using Tapatalk 2 Quote
