This clutch is much smoother than the 4 pin. However as traction builds I will always have a 4 pin ready. Wham Bamm THANK YOU MAMA!
I'm running a MAX POWER XL9, 16/49 first. It is summer time here in Florida so we are running on tracks that have not seen alot of racing, but have seen alot of rain and the azzfualt temps are running a close third place to Arizona and Hell. With the MSR spring, .4mm gap and the 3.75 drilled shoes spring tension has hovered around .7 to .9 . Very drivable and not eating shoe's.
Thanks for the reply, Yea, its hot and muggy here in Houston also, but not
much rain this summer. Gulf Coast raceway has re-surfaced their track and
we have been running quite a bit of practice the last two weeks preparing for
the SWS series race this coming weekend.
I also have tried the 3 pin clutch using your suggestion from your previous
posting of one 3.5 mm hole put near the end of the flyweight, msr spring, .4 mm gap, spring tension at .82. The clutch is indeed very smooth. I am running
a Murnan Flash 21 with a 16/50 First gear. However, I will more than likely run
an aggressive 4 pin clutch at the SWS series race this weekend. Our track is
tight with some fairly long short chutes. You really need the bottom end grunt
to get out of the corners. The traction on this fine grain asphalt is very good
now with just a few people running on it with no sugar water. I'm sure with a
few more cars running the track the traction will be insane.
Thanks for your help,
Dale
