but i have to say, the times & 60ft your mate ran are top's for first time at the track! so well don't to you both

i'm & old bloke of 65 & will get to the track after a 300k+ ride up coast to check what i can do on my ol carb Buell now

 

ahhahah we should start a HD forums list of times...

i just had a thought, i think maybe my Ricor Intiminators maybe stopping the quick transfer of weight to the rear causing the rear tyre no to be loaded enough, what do you think?

You got balls, im scared to jump on the freeway on mine.

Not farmiliar with that product? ( Rico intimidators ) can depend on technique you use.

you might be trying too hard, riding clutch can help, but sometimes wheelspin helps as keeps revs up ( power & tq up ), just if you can keep it straight, if you fishtail you go further.

looking at the time your mate done , the speeds dictate how much power to weight he has, he does not have enough for 10.50 would need to do 100mph or higher half track and about 125mph or higher full quarter with a 60ft time about 1.55  1.6, like he was 1.7 60ft did 11.3 if got down to 1.55 could run 11.0.

but might ask daddyracer56 what he thinks as he has race twin cams in 88, 95 , 96 , 103, 113, 120, 124.  & maybe more that's just the twin cams i've personaly seen him raceing he has all the time tickets & some dyno numbers. i have seen him run in the 9's with Harley frame twin cam dyna no wheelie bar no ignition cut out just foot shift use stock Harley wheels & street tyres, i was racing the day he ran the times. 

 

 

http://store.ricorshocks.com/FAQ_s/41.htm  these are the valving im using in the front, they work really well on the street but not sure if they are going to help with drag racing a bike...

 

Forget the fatboy dude there is no points to be proven there, as the rider has allot to learn (more than me) he short shifts the bike etc... give it time and when he has some confidence i'll post some results until then his time is irrelevant to the power it makes at this point in time.

thanks for link, a while back i strapped my front down at track, lost traction bad, took straps off & traction was better, but the lower the better at the track.

 

i set the rear springs too hardest adjustment for when you launch because all the weight transfers rearward

What gearing did you have on you 883?

Hi, those are pretty good results. I am wanting to do some power upgrades to my 883. What have you done to get those dyno results? I was just reading this article:

http://www.motorcycle-usa.com/413/13194/Motorcycle-Article/Harley-Davidson-Sportster-Exhaust-Shootout.aspx

and they are getting similar results to you, but they are using a 48 with the 1200 motor.

Awesome results dude, well done.
Interested to see the results after some tickling around,,,,,,,,,

Only mods are : pipes, air cleaner and a "proper" tune. And ride hard!

T1

that's a pretty good time, the best i have managed to get at willowbank raceway is 13.01

Mine is a 48 sportster 1200cc with all the stage one gear
*screaming eagle air filter in std airbox
*V&H short shots with quiet baffles
*SEPT with generic stage 1 tune

I would like to do some more to it to crack into the low 12's but not sure what to do next
