Anyone drag race there dyna's, got a 2013 streetbob with a 120r in it, looking at racing it next year, just need some info on suspension setups ????

Yep, drag my 2007 bob regularly.
Daddyracer, a member on here, drags a 120R dyna for frasers regularly also.

do you just run your stock shocks ?? im thinking of lowering 2 inch front and back to help launch

Stock setup is fine to start with, pretty sure daddyracer runs low tens on a relatively stock setup, except for engine. Lol
I have run stock, but normally drop the forks through the trees an inch or two, with ikon 11's on the rear, bump the preload to max on them and they are as good as solid.
How much hp ya playing with??

I have upped the compression a bit from stock and put a larger throttle body in for a start, havn't dyno'd as yet but the boys reckon 120 + hp, just trying to stop it wheel standing on the launch

Probably easier to play with clutch method to control wheelies, it's all in the hands.
Daddyracer will show up here eventually, he is the man, or even KrashKinkade might chime in, those boys been dragging for years.
I found less is more on the start line with street HD's, less throttle more clutch, get 'em going and then hang on. Lol
there are a few videos on YouTube showing local boys draggin.

Yeah thanks mate, i ran an 11.81 on a borrowed 1998 113 ci wide glide, so i went out and bought the 120r lol caught the bug lol thanks for the info mate

Fuck yeah I've been waiting for something like this to pop up. I would love to take my bob down the motorplex once i can get the 120r in it.

Should go good with a 120r in it Ryno, looking at high 10s as a start

I race mine regularly. Lowered front trough trees about inch and rear springs on lowest steting. I reckon you need it soft ishish to suck up the launch. If is low it won't lift much. If its hard there's no escape for excess energy. You either spin the tyre or lift the front. Time spent on the track will figure it out.
