Drag racing????? 1/4 mile times and speeds...

Buellxb Forum

Help Support Buellxb Forum:

Took my '03 Xb9s to the somewhat local drag strip (St.Thomas Dragway about a 2hr ride).. My best for the night out of 8 runs was a 12.46..
 
wow old thread,

Posted my best on another thread but was:

Almost 2 years ago i ran a 12.03 at 112mph with a 1.98 60ft. Had the whole airbox and filter OFF on a cold night running 110 race gas.

Ran it a couple weeks ago with 93 octane, and entire filter and air box ON and my best run was 12.32 at 110mph and a 2.03 60ft.
 
Ok, can someone help me here. I've seen U-Tube videos of Buell's getting off the line and they sound like they're sorta bogging it out of the hole. When I road raced (125GP and BOTT) when the light goes green I pinned the throttle and feathered the clutch till it was all the way out, at that point I'm topped out in first , bang secong and I'm gone. Am I missing something here? Wayne
 
i have a 04 xb12R and i usually run about 11.90s with it... once in a while an 89 or 88... i have open air box tuned with ecm spy on a buddys dyno and then a Latus pipe... works pretty good and the latus is by far the best sounding pipe out there...

anywho... i have a buddy that lives right here in town with a 2003 xb9s kinda customed out with pretty much the same mods as my 12, same pipe open air box and ecm spy and he can actually keep up with my 12 no problem.... once in a while i even get beat... in my opinion the 9's are pretty much just as fast as the 12's a little more grunt and thats about it and once there tuned there pretty much even cause the 9 revs higher and quicker...
 
Well I will start off by saying the bike is a 2003 XB9r. It has the race kit and that is it for performance. I weigh in at 180, and with the bike we totall out a 630 lbs, and that is with 1 gallon of fuel. Also I was running 110 octane temp was 65 deg.
Best.
Reaction- .8409
60ft- 1.9890

ET @ n594ft- 7.2609
1/8 mile ET- 7.7439
1/8 mile MPH- 93.15

Interested in your full times on 12's to compair with where I may have the upper and lower hand with a 9.

These are from my other Drag racing post but since this is seeing more action figured I would try tho throw this in to see what I get out of it.

thats how best times are achieved on street bikes ,, on the gas as soon as possible just above the bog point or slight bog...watch how some of these paid factory riders get numbers for vmax or busa v65 or any bike ...like they bogged out of the hole with no tire spin....need close to 100 hp to run low 11.s
 
ok i have 3 slips from 2 months ago when furball and i went. the 3rd slip is from the video when furball and i raced and we both bogged off the line pretty good.

so my 12 is slower than your 9 so far xtremelow.

im going tonight to hopefully change that.

more slips to be posted tomorrow!!!!
 
I hope tou guys arent buming out on those low 12 times,as the are pretty good considering there coming out of a air cooled v twin with epa legal cams,and covered with all the street legal gadgets.Another thing to consider is when motorcycle mags do quarter mile tests,its not done in the methods of the past.they used to use a small rider like pee wee gleason and take a trip to a drag strip an let him do run after run until the best time or sometimes 3best times were achieved, and publish it.Here in the gadget age ,they use instruments, bike mounted and calibrated to final drive ratio,and triggered by the speedo send ing pulse.there is no reaction time involved,no light,so the et is reflecting the performance of the bike with the lightest rider they can mount on it.the 750 kaw triple ,stock, ran in the low 12s ,but was the only street legal production bike to do so for ten straight years.Dont worry be happy,and happy holidays
 
My best 0 to 60 times came on my hot rod sportster,by holding enough throttle to have about 3500,simultaneously dumping clutch and twisting to max throttle as bike got under load.Slow on throttle you will bog,to quick and you might get out of shape a little or the tire will come up a little. With all these possibilities ,my times were varied by no more than 2 tenths in the quarter.You find the sweet spot by repeating.The og clutch is still fine.
 
I have an 08 12R. I've been to the strip on it once, I ran a 12.04 at 114, and a 12.05@115. Both runs my 60' was over 2.5 seconds, horrible launches. This was also my first time at the strip running through the lights. Normally it was run what you brung with a street racing style start(still at the strip).

This is a vid of my run @114 I believe. I am on the inside, 05 R6 in the outside. Unfortubately my buddy in the vid was right, I didn't have the top end.

Thanks for the drag race coverage.I went to motorcyclistonline and there quarter mile test seems to have been done on rolling chassis dyno.So actual wind resistence could be missing from there et calculations.I dont think your et is far from what should be expected and your 60'is fine from what is visable.I found at least with my sportster,gear shifts after 6000 but before the rev limiter got better results. Also,A couple local guys were running 8th miles at irwindale on thurs nights,there ets and speeds improved with a 30 tooth aluminum counter shaft pulley.Im not sugesting you do this with the buell as your first gear is almost the same as that already.It does tell me the power charecteristics of the motor ,favor using its torque as soon as possible,via load.For example With taller gearing and 18 inch rear wheel on the sportster,I could finish a quarter mile at the top of third, or the bottom of fourth.Bottom of fourth added 2 mph, and brought et down from 12.3 to 12.1. So you might want to experament.Hope Ive been helpfull, not techninally boreing.
 
i hope i can make my xb12r beat my brothers duc 996,raced him with my zx7rr alot and we were bolth in the mid 11 sec range.hopeing a filter/exhaust and programing will be enough..if not n.o.s. will be needed.

Yeah the launch was definitely not there. Sounded like you kinda let out the clutch then started revving it up?

Best launch I can do is to hold it at 2500, the while I'm releasing the clutch raise the rpm to somewhere past 3000 and work the clutch to keep the tire down while on my way to full throttle, this all happens in 1-2 seconds (which should be your 60ft time) I launch so hard now that I'm starting to loose traction. Been told my tire will spin half a turn before it completely gets going, and the scratches in the tire proves this. Has anyone here dropped air pressure to help the launch? If so what psi?
 
On my old ZRX1200R I got to make one free pass down Fomoso track on a hot summer night. Lost the timeslip long ago but I remember my reaction time was .49! I was watching the other guy. Trap speed was 125 and I think it was 11.50 seconds at the quarter. Dont remember any of the other times.
 
I ran my 09 1125cr at firebird raceway in chandler AZ oct 16th 09 about 2 weeks after I bought it... maybe had 400 miles on it bone stock with a FMF slip on and a K&N air filter... no tune... First pass(only pass):
r/t-.501
60 -1.835
330-4.781
1/8-7.121
mph-106.41
1000-9.149
1/4 - 10.889
mph-128.01

they kicked me off the track for exceding 120mph w/o a full leather suit... :(

Also It was my first run and I was jittery... the guy next to me rolled up first and staged both lights right away so I felt rushed... I rolled up and also set up both lights... left my F-ing visor up! took off and could not keep the front wheel down thru first or second gear... had to keep getting out of it, then end of second I realized the visor was up so I was doing a face slap move to try to close it w/o letting off... finally got it most of the way down and the wind snapped it shut but I was not really concentrating on good shift points....
I think I could break into the 9's with some practice and now that I have a tuner.. may need to get a strap?
First thing is to get a suit as I want to do road track days anyways... Pricey thou!
