A question for you drag race junkies, 60' Hey guys its been a while since Ive posted here, but I need some more opinions. I no longer have the 14, but still think both bikes are great . And used to get good info over here. So...
Does rider weight have anything to do with your 60' times? Ive been wondering this for a bit now. I have seen a few guys pulling 1.3x 60' times on stock clutch 62" bikes(no bar), and have made that my goal. But after making over 75 passes or so at 62" I havent been able to get into the 1.3's and want to know why . My best 60' has been a 1.40 but they are usually 1.41-1.44's. This is on a 08 busa with brocks clutch mod and cushion kit if that matters. And im a bit over 230lbs suited.
I understand that the heavier you are the harder it is to accelerate, but I would think that weight would play a bigger role after the 330'. Its not really a power thing for good 60's is it? I mean I can get the bike to wheelie at any point off the line to 2nd gear.
I guess Im really wondering if there are any 220 plus lb riders cuting 1.3x 60's at 62" or shorter with a stock clutch and no bar.
Is it easier for a lighter guy to keep the front end down?
And I know it all comes down to seat time, which I have quite a bit of.

No matter how you cut it, that is a lot of mass to get moving. You have a finite amount of power that you can put to the ground to move that mass, without wheelying the bike. And being a larger guy, the CG of the bike is higher, making it more wheelie-prone.
I'm not saying it's not possible, just that yes...your weight and size are going to be a factor in your 60 foot.

yes, the lighter you are, the less the bike will want to wheelie, and its easier to get less weight moving quicker from a dead stop

ive also said the 60' doesnt make a good pass, 330' tells the story, you can cut a great 60 then blow it from the 60 to the 330 by getting a big wheelie and backing out of the throttle after the 60'

Yes, a quick 60' is nothing without the 330'. I don't know why many people focus so exclusively on the 60'....so many runs are blown at the top of 1st gear! Not saying this is the case here, but you see it all of the time.
how so, man its funny ever since you first replied to one of my posts a long, long time ago on the gixxer.com forums you have rubbed me the wrong way and you still do to this day

Thanks for the replies, helpful. And I see what your saying, its just been something that Ive wanted to do since I read about others on here being able to do it. A good 330' for me is 3.787's. Is there room for improvement? Whats a good 330 for 62" bike. Again thanks for the replies

What are your times on your busa vs the 14? I thought someone would have asked by now

While I don't know much and I haven't run fast times, it seems to me that a bigger rider would make the bike more wheelie prone as it shifts the center of gravity higher depending on how much the rider weighs. The rider is the highest point of the motorcycle, and the seat is also behind the center of gravity. Even with classes putting a restriction on minimum weight of bike AND rider, the big guys still have a disadvantage. Notice that all the small guys add weight to the front/bottom part of the bike. Oh well......... I wasn't complaining about being big when I was playing football! haha

Here are a couple of slips from last weekend. They seem to run real close ET wise, but the busa pulls some crazy mph. It usually traps in the 156's but we had some great air this weekend. Pretty much same mods to the busa and the 14. The busa might be a bit lighter, Ive added marchesini alm. wheels and a lightweight battery.

I agree with this too. It also takes more torque to move the heavier object and more torque with heavier weight higher up means wheelies. Racers, for a guy your size and wheelbase you are definitely getting it done. We wont hold it against you that your 8 sec pass came on the Busa first...You will have to add 2 inches wb to make consistent 1.3x short times.

Same mods but i have light weight wheels and battery on my busa ...lol ok .... I'm just bustin your balls ...... Looks to me that you are doing just fine , so i wouldn't lose any sleep over not hitting 1.30s ...Most of my passes are 1.40 , sometimes i'm feeling it and bust off 1.30s .. I have been as low as 1.34 but they are hard to come by ... Just keep riding it like you are now and i'd bet money you will get into the 1.30s

That bike is certainly hauling ass.............Just keep doing what you are doing and focus on your 330 times. There are no Busas around here running that mph.
