What’s the gearing combo for a??

What kind of motorcycle do you have?

What size is the engine?

How long is the bike?

What is your weight?

Do you have a turbo?

Do you have nitros?

We would love to help, but you will have to be more specific.

Thanks

How long is the bike?

Do you spray it in the throttle?

What kind of clutch?

Do you have a lock up?

Do you have an air shifter?

What kind of tire do you run?

What mph did you run in the past?

What rpm were you at when you went through the traps?

16/38 or 39

Go through the traps at the top of 4th off the spray.

Go through the traps in 5th on the spray.

You have to be able to ride the bike....if it is acting up, you will never see good et's.

Good et's are based on the amount of average horsepower applied to the track....if you lift due to wheelies or spin, you won't ET... or MPH!

If your bike is spinning up top, you need a better rear shock and/or lower gearing.

SpyBusa…I don’t think your getting it…..

There is no MAGIC gear ratio! Look at all of your variables…anyone who throws out a solid number to you would be A fool!! 

I can’t even tell you the gear ratio on my Bandit!
No kidding…..I’d have to count the teeth or knock the dust off of my notes. (I grind the numbers off of my sprockets to prevent prying eyes from benefiting from my hard work. Also, when someone brazenly asks my gearing…..I can tell them I don’t know without being untruthful!!)  

THE GEAR RATIO DOESN’T MATTER….. The sprocket combination on my Bandit is the one which works the best for all of MY variables….riding skill and size/power level/chassis and suspension configuration/ clutch adjustment……the list goes on forever. What is on there has been proven to work and that is all that counts. 

Starting with completely stock bikes (our StreetSmart Hayabusa product line, for example)….we are all on the same page. I can give solid definite answers because we all have identical bikes. 

Once you move into the custom realm….you must figure it out yourself…I can only direct you. 

Good Luck!

What size is the engine? STOCK BORE

BOSSMAN,

You should have our Ultra Clutch Mod (S13-CM-ULTRA) and Clutch Cushion Kit (S13-CCK-02).

The Clutch Cushion has a lever cam for the clutch lever with 2 extra positions, you need this with the cushion or extra spring pressure or you will have clutch creep.

Also need to take into account where your rear axle ends up.

A slight gain from gearing COULD hurt your overall performance if the axle is further foward.........................nothing is simple in this silly game of drag racing  

Lots of variables go into gearing, there is no magic set up.  I would start by going one tooth down in the front and then test and tune to see what you will need to do in the back.  As a rule of thumb with stock wheelbase you will want to cross the finish line in the quarter mile at the top of fourth gear just before you hit the rev limiter.

Brock I have a question.....Im 6'4" weigh 258 lbs,265 or so suited,I have a 08 busa 68" W/B.. 1441 motor 395/378 web cams degreed at 106/108,stock clutch,with your cushion and mod,Im currently running 17-46 gear combo and the best 60 ft was a 1.49. What i wonder is am I running the right combo for my weight?...what would you reccomend as a starting point for a lower gear ratio,good 60' and MPH....thanks James
