Sprockets...

[KnKBusaRacing]

I think my 03 is geared for 1/8th mile.. not sure if its +1/-2 or -1/+2.. i know the rear sprocket is a 42..

what sprockets would be better geared 1/4 mile? i shift into 6th about 20ft from the traps.

Stock motor, hindle full exhaust, and sprockets is all the "motor work" done.. it is stretched 6 if that makes a diff

Thats a pretty good ratio for an all motor bike if you still ride it on the street.

but wouldnt it be better if i was wrapping 5th out right at, or right past the traps?

yes,16/42-43 will put you there.,just make sure your chain is adjusted right.

the chain has very little slack in it.. i mean VERY LITTLE.. im a big guy 320ish, and when i put smaller guys on the bike, its low 9s.. 9.2, 9.3 etc... but the best i have gotten it to is a 10.07. its tickin me off.. but then again, like i said in my other post.. ALOT of miles on stock clutches

 

[nitrousjunkie]

Dont have it too tight,also get some heavier springs when you replace your clutches.

what sprocket combo would be best for me then? like i said, i want to STOP shifting into 6th at the traps..

my times are:

R/T ... .168
60' .... 1.574
330 ... 4.199
1/8 ... 6.428
MPH .. 110.25
1000 .. 8.389
1/4 .... 10.074
MPH ... 132.70

i KNOW i have to be losing soemthin on the big end being that i am shifting that close to the traps

Try 16/43 and leave at about 6-7 grand,you got to keep those rpms up,slip the clutch in 1rst,get wide open while feeding more clutch,it takes practice.

 

[KnKBusaRacing]

aight.. ill order the 43 here in the next few days..

i also made a post about clutches.. I race alot more than i ride it on the street, and my clutches are slipping bad. wheres the best place to get a new set, or what would be my best bet

 

[CYCLEERIC]

make sure the clutch is out and you're full throttle as soon as you can without a huge wheelie. The quicker you off the clutch and full throttle the better 60' time you'll have and the better it gets the better the run will be . More seat time will also improve your reaction time and ETs

16/44 on a stock motor should go top of 5th...

 

[busa crazy]

you might want to try the brock clutch mod or maybe a lockup or multistage,because clutch will tend to slip in the higher gears in the 1/4. i was around 260lbs last year and i had a similar problem,i went with brock set up!!

 

[McyMike]

I don't see how your hitting 6th with those ratios? Sure it is 6th and not 5th??

 

[busadt]

im running 16/45 gearing going thru at the top of 5th, im 270 my best et 9.63@145mph 1/4. gonna try sprocket change to try top of 6th. anyone have a good 47-48 sprocket they want to part with?
