WF Sprocket Size for Road Racing

What would be a good assortment of a few sprockets for Road Racing?
I'm guessing you would want to start with the largest fronts 20-22 front and smallest rears 64-68 rear?

Good guess, a lot depends on the track you're running.

There's an excel spreadsheet here

called clutchgears.xls that you can play around with ratios on.

Also check with Benn Herr (he's the man behind southwest karters) since his kid used to run WF at Thunderbird there.

Good luck,

Tracks will be all the west coast that NCKroadracing runs at.

I ran a 21 driver at all the RRs last year. I ran a 21/ 60 at Laguna last year but was on the rev limiter all the way down the back staight. Hope that helps

Rich,

Thanks can you guide me to split sprockets under 64T that is the smallest I can seem to find.

Thanks
David

IF you are running 219 it is best to get a 23 or 24 driver sprocket. Most of the west coast tracks ratio will be 2.7-2.9 to 1 ratio.
