Cant seem to get my bike out of the 1.6 range, I ve played with tire pressure, gearing ride height. What are somethings I can do to get my bike to 60ft better? I have rode it with a bar and with out, still the same times.

I run 15 extremes, 74 r/o. Wish I could remember my 60 ft times, but they were better than that; but not great. I think I could even run more paddle. What is your mph?
edit: This on my 4 mil, stock chassis, like yours, not the one below.

I was in the 1.61-1.64 mark most of last year using the 13 extreme's.

what length swing arm r you running , what i try to do is run as less paddles ,as i can get away with and still maintain traction . If you run a bar make it at least 6ft long . Keep the tires you have been running and start taking inches from your swing arm ,until it goes on the bar smooth and holds the wheels up at lest 75 ft out or more . Set the bar so that your front wheels float in the air about 6 in from the ground. if the front wheels go much higher than that you are losing time and it will be hard to control .if you go to far in and it starts slamming the bar, try a little less paddle or go back out 1 or 2 in until it goes on the bar smooth at take off. i now its a lot of work but its well worth it, it has always worked for me . your 60ft times and mph should increase all so . win you can do both your et's will drop . you could run a long swing arm and a lot of paddles to make it hook , but your mph will suffer. it takes a good combination of 60ft and mph to make a quick bike . most people want to go to a bigger motor , or just keep tuning on there motor ,because its not running hard .when you know your motor tuned right, leave it alone and start looking at your chases setup and tune it over and over again and leave the motor alone . i just about guarantee you will find et . i just think if people would focus on what they have ,instead of thinking bigger is better and work on the chases as much as they tune their motor ,they wold be surprised at what they could get out of their set up . thats the best lesson my dad passed on to me about the sport of sand drag racing . he did it for 50 years and he beat that into my head ,for the 28 years that i spent with him .
win i go back to the chases set up, over the motor i always find et . he always said its 10% driver 15% motor 75% tuning . I'm not saying you tune your motor to much, or you want a bigger motor, I'm just passing on what was taught to me and has always worked for me . maybe it can help some one else also

right now I am running a 10 over swinger that is strutted, 22-11-8 11 paddle extreams, bike has bested a 4.25 at I think it was 75 mph. with a 1.61 60ft.
that was with no bar though.
thank you for the replies fellas I will give some of these ideas a try.
thank you shaker! that is some really helpful info!!!
I two was considering a bigger motor, but I really would like to see how far I can push this little 4 mill!!

I'd see if you can find some 12 or 14 paddles with a 74 RO or something close. I ran 14 paddle extremes, 72 RO and would spin out of the hole but it would pick up in second and take off...All I needed was a little more RO but I went ahead and got my 14 paddle staggereds because I knew I'd need them for the 10mil. The reason I suggest the tires is because they're a lot easier to borrow from a friend than another swingarm...and you can try before you buy so you're not throwing money down the drain just to try and pick up a tenth. A shorter swingarm will help you get a little more traction but I think you're good with the 10 over. If I were to do my 4mil cub over again I would have gone with a 10 over swingarm.
Just to give you a little fuel for your fire, I ran a best of 4.13 on my 4mil before I pulled it out. Backed it up with a 4.15, and a couple 4.17's. You can get there, I know you have pretty much the same engine setup/port that I ran.

Travis was that 4.13 with a bar? or without a bar?
JT Is there a chance that your coming back onto the bar too hard and unloading the tires?

That's with a bar, I don't race without it.
Your theory is very possible and I've seen it happen a lot, to myself and others....One thing that can help with that is letting most, if not all the air out of your wheelie bar tire...it'll allow it to give just a little bit more...just an idea to play with

without going into making a long post,,,,alot of things make up your 60 and the track surface is a HUGE HUGE factor,just remember the more paddle you add the slower your topend will be, paddles,gearing,position on the seat,height of the wheelie bar are all things affecting a 60ft

Nice post Carolina... that's one reason I'm glad I kept the same motor and chassis as last year. The motor is strong, I can concentrate on tuning the chassis now.
JT...we are never gonna 60ft at Bobs like they guys down in Gilbert did. Period.
My bike was slower at WMSD than Bobs...and that was with the bar.... That 4 mil runs good...keep working on the chassis setup.
When i borrowed Hopper's 15 Paddle Ex last year, my 60 picked up, MPH did NOT change....and ETs picked up a hair...
I'm convinced we need more paddle and possibly start trying some bigger rollout tires and staggered....
I'd like to try Brady's 16 staggers that are like 80 rollout...just for giggles..
