sand drag

[krauss4]

going to the dunes here in a few weeks. im geared at 17 38 with 20 inch holeshot tires for the dunes im going to be running 22 inch 8 paddel tires. will i need to down my gearing. racing in wet sand

[krauss4]

what im getting at is do paddles load the motor more in san or spin more than dirt tires

14/42 is about the average gearing for duning here.. with a bolt on bike

 

what dunes are you going to?

 

Sand robs alot of power from the bike.

17/38 seems a little high to me for racing; not sure about just riding around. This also depends on how much tq and hp your motor has..and your weight.

 

I run 15/42 on alky on both my 421 and 392 Cubs. It's difficult to keep the revs up enough to launch in second on the 392, but blows the tires off on the 421. This is with 74 r/o 22x11x8 extremes. (10,14, or 15 pdl)

Try some Rippers :biggrin:

 

I'm going to try 14/41 with some 10 or 12 paddle extremes at the races this weekend on a 421 cub, maybe some 14's if I can get a wheelie bar mounted up and it'll launch in 2nd.

I've got some 16 pdl 83 r/o Rippers coming, but that's way too much tire for my 421. Might try the 14 pdl staggereds on 10x10s on the 421, and the 16 pdl ripper on the Cheetah.
