Smashed my previous best

[NightCrawler]

Well here are my numbers
Previous best
60ft = 1.970 1/8th = 6.817 Speed = 115.0

New best
60ft = 1.744 1/8th = 6.565 Speed = 114.7

Okay ... so why do I feel I suck even though I beat my previous best by nearly 3 tenths (in the 1/8th no less)? Its because my previous best was done with stock 17/40 gearing and my new best was put down with 16/43. I really expected more.

I remember reading on Brock's forum that with his mods a "competent" rider will run high 6.2's at 120mph. I have everything he listed except for the cushion mod but I instead have a 43T sprocket in the rear and the best I could muster up was a 6.5 . On top of that I only weight 160lbs.

I'm guessing the only reason my time dropped is because my bike is now quicker, but it seems as if I myself haven't improved. Most of my runs were in the 6.6x area, and I'd credit the gearing for that. I'm not sure what else I can do though. On that run I had the clutch out and throttle pinned just before the tree (which stands a few feet before the 60ft mark) and carried the front wheel about an inch or 2 all through 1st gear. It came down when I kicked it into second. Basically, that was a pretty hard launch and I still managed a 6.56 on that run.

I'm happy but frustrated at the same time. Any tips on getting this crappy dragger into the 6.2/6.1 territory?

That is quite a bit of difference 2.3 tenths in your 60'. You are good for another 1-1.5 tenths in the 60'. Get some more seat time with the gearing and it should fall!

 

[NightCrawler]

Thanks.
I think I could have dropped a tad bit more had I not filled the tank before hitting the strip. With the new gearing I didn't want to risk the front wheel coming up too much so I weighed the bike down with fuel.

Another thing I could have done to drop my time is actually race against someone. On my 6.8x runs, there was someone in the next lane and those were my quickest runs. I think racing someone would get me to push harder than running alone.

Oh well, there always next week ...

2/10 off any part of a run is a good shot..

You may want to experiment with shift points as you have new gearing too... we found often that short shifting (early shift) would help on some motors.

I would not be unhappy at all with your new best considering you did not add any hp to the engine

 

[Moparict]

Your 60's are high. You need some more seat time and they will fall. Brocks' idea of "competent" is a rider who cuts 1.45-1.55 in the 60'. You do that, and you will have the time you want. Seat time, seat time, seat time. Nuff said. Good job on the improvement.

 

[NightCrawler]

Thanks fellas.

Short shift eh'? I was shifting between 10,5000 and 11,000. Are you suggesting maybe around 10,000?

And yeah, I'm trying to get the best possible time I can get without adding any HP. I'm thinking of removing my airbox next time and shedding some weight from the bike. I ride with the grabrail installed with the hump and also have a second battery for my LEDs. I might leave all three at home next time.

I'm sure my gearing helped my 60ft times but I admit I was pretty relentless practicing the past 2 weeks. There's a dead road by my job and I practiced there every night I rode.

Another thing I forgot to mention. Todays runs were done in the day time, my previous best was a night run ... it was much cooler. I wonder what would my times look like if I had run at night this time around ...

 

[GIXERHP]

Practice Practice!

I don't know where you are getting out of the clutch, but when I change my fofus from best 60ft to best 330's, I started letting the clutch go really quick, my 60ft suffered a tad but my 330's and 1/8 dropped big time.

My clutch was out before I reached the tree which is a bit before the 60ft mark.

well Im 270 suited and ran a best of 1.92 60ft, 6.979 in the 1/8 at 108.25

first time at the track on new bike 04 busa full hindle, strapped, lowered, pcII, 17/40, hard to launch clutch was almost gone. cant wait for it to warm up out hear in chicago, i got an 9 over arm, head port, duel intake cams sidewinder with 16/44 or 16/46 not sure yet

well first,less gas and weight on the bike will help.
shift at 10,000rpm.
is your bike strapped and lowered?

 

[99'busa]

i dont know how much it would help with the 60' time but do you keep your feet down through your 2nd shift. only assuming you do have a qickshifter.

 

[SKILLZ]

Keep it up!!

Yes. 3 inch drop front and rear.

I launch with both feet down but pick them up just past the 60ft mark.

 

[bquinn]

Practice, keep track of everything you do/try, don't be afraid to try different launches, shift points and such, practice....AND PRACTICE

 

[hayabusa99bw]

your mile an hour is definately there for a low 6.10 to 6.0 you just need seat time to get your sixty foot down.

 

[Blue Streak]

I think you have to much gear for your weight, all you need is 1 down in the front at stock wheelbase. What RPM are you leaving at? I use to leave between 2500-3000rpm when my bike had a Brock pipe & track map, lowered, air box mod, and a 16 tooth front. I ran 1.56 60' and 6.20's at 121mph setup just like that and I weigh 168lbs in street cloths. Remember smooth is fast and I think seat time will help you more than anything.  

I took Yamahor's (Bens) bike and ran 6.42 my first and only pass ever on it and it was bone stock just strapped and lowered a tiny bit in the rear. Since it was my first pass on it I took it easy, the bike had low 30's in it but I never got to make anymore pass's on it.

 

[NightCrawler]

I've removed the 43T and went back to the 16/40 setup. I did that because I wasn't leaving as hard as I thought I should due to the fear of the front wheel coming up. I'm much more confident with the 16/40 but never actually tried it out. My previous runs were all with stock gearing.
