Title: lets not forget the drag racers!
Post by: ineedanap on April 16, 2009, 08:36:44 PM
drag racing is racing too!  Here's a picture of me on my other bike from last year.  Taking the GS next.  Anybody put down some good times on a GS?

Well I dunno.  It's like NASCAR but without even the left turns! :tongue2:

That said when you get out there, make sure to post your 1/4 mile times!

I've hit 13.08 @ 100mph with a 1.916 60ft. I got pretty much every thing done to the bike, wiseco pistons port & polish heads full exhaust, k&n, etc. I got to tune the carbs more, after that, I will hit 12's easely.

Will keep you informed

What gearing did you have?

what gear and RPM you crossing the strip at?
Title: Re: lets not forget the drag racers!
Post by: gabordi on May 07, 2009, 07:47:03 AM
I'm running 15t front sprocket and standard rear. I did not looked at what rpm I cross the line but it is around 8k

Wow!  That's alot better than I thought a GS would do.  If you got lucky in the first sixty feet you'd be well into the 12s, even without dialing in the carbs.  NICE WORK!

Post by: brickerenator on May 07, 2009, 11:50:53 AM
That's a nice 60ft for a car, I dunno about bikes.
Title: Re: lets not forget the drag racers!
Post by: gabordi on May 07, 2009, 08:37:11 PM
Thanks! It is not so bad for bikes too I am shure that I can go low 1.8 with the power I have with lot of practice. Motorcycles usualy do 1.8-2.0 60ft even if they got liter sport bike because they don't handle the power but they can go as low as 1.6-1.7 after that they need longer swing arm.

Right now I am waiting for a new stator coil because the one I have just blew 2 weeks ago. As soon I receive it I'll go to the track to see a 12 second pass from that gs500... euhm gs554 now with the bored pistons lol.

I went and ran at bristol dragway last night, and my best time was a 14.970 at 85.73 mph with a .008 reaction time!  from there my runs hovered around the 15 second mark
Title: Re: lets not forget the drag racers!
Post by: jeremy_nash on July 24, 2009, 05:45:47 AM
bike is running lean, and I'm pretty sure its time for a valve adjustment anyway
Title: Re: lets not forget the drag racers!
Post by: ineedanap on July 24, 2009, 09:43:44 PM
Eight thousanths of a second!  Nice reaction time.  Was that your first time out or have you been doing it for awhile?
Title: Re: lets not forget the drag racers!
Post by: jeremy_nash on July 26, 2009, 07:34:08 PM
first time out, never been on a dragstrip before, on bike or car.
my first run was a .313 rt, second was .008   and red lighted on the other 4 runs.  funny thing is even though my runs
vcaried a fair bit, no 2 runs were more than 1.5 mph trap speed difference.  my main problem was getting off the line consistently, my first run was like a 16.2 then my second run was my fastest of the night, being a 14.97.  if I could launch the thing properly, and tuck, I should be in the mid 14s hopefully.  but thats only gonna come with time, and I'm in no hurry, I was the slowest bike, but I guarantee I had the most fun!
Title: Re: lets not forget the drag racers!
Post by: ineedanap on July 26, 2009, 07:50:26 PM
I had a veteran racer explain to me back in the day that the MPH is a good indication of horsepower and doesn't vary much from run to run.  He also said people their carb/injection tuning based on MPH and not ET because it gives you a good indication of what's going on with your motor.  Don't know if it's right, but sounds like it might be.

Try to talk to people at the track.  They will usually have good advise and most people are happy to help out.   A single tip on launching from a guy at the track got me from consistant 10.40's to consistant 9.90's in one outing. 

Once again, nice job.  Sounds like you picked it up much faster than I did my first time out.

thanks, and we'll see next time they have a street fight night
Title: Re: lets not forget the drag racers!
Post by: cstilt on July 27, 2009, 05:38:50 PM
It's true, he had a blast. You could see him smiling through his helmet in stands. lol  Maybe one of these days I'll get some leathers and we'll compare a stock GS to your modded one. I should be a bit slower consider you've got a pipe, jet and gear in yours I believe.  I wish I could remember what the magazines tested the quarter mile at. 13something is stuck in my mind but I'm not sure.

BTW, you guys set a heck of a pace through the twisties this weekend. I was impressed.

When is the next street fight coming up?
Title: Re: lets not forget the drag racers!
Post by: jeremy_nash on July 29, 2009, 09:12:32 PM
yeah, and we were taking it easy on account of the roads being wet.  you should see us when the roads are dry   :icon_twisted:  my 160 earns its right on the bike     :woohoo:     next streetfight will be on the 29th of august.

Low 13 seconds on a naturally aspirated GS... I'm gonna need to see some time sheets.   :cheers:

Apparently I was drinking when I said that. Cause I was so far beyond wrong it wasn't funny and I'll admitt to that. Not sure why 13s were stuck in my mind.  When MCN tested the F model it was 14.67 @ 88.3mph.  I got that from here: http://www.mcnews.com/mcn/model_eval/NinjaGScomparo07a.pdf

I apologize for being wrong.

Jeremy, that was a slow pace? lol  Maybe I need to reconsider riding with you guys.  I wouldn't have a chance.
Title: Re: lets not forget the drag racers!
Post by: jeremy_nash on July 31, 2009, 07:21:29 PM
you should be able to keep up with me without much problem.  as 500 riders we make up for the straight aways  with our cornering ability.  in the twisties, thats about our pace, but we generally ride faster on the straighter roads.

so I finally got around to scanning in my timeslips, kinda hard to read, but cant do anything about it  :technical:

If I wan't to lunch to bike as fast a possible at what RPM should I release the clutch?
Title: Re: lets not forget the drag racers!
Post by: jeremy_nash on November 02, 2009, 09:24:56 PM
my guess would be wide open, and feather off the clutch.  I was bogging pretty bad off the line, hence my pretty slow times.  neither I nor gstwins.com is responsible for any damage to your bike though.  lol

Somewhere between GSXR and TL... lulz.

Seriously though,  buy a new bike.

I'm planning on taken mine to Irwindale speedway in SoCal soon. It's only an 1/8th mile track.

What do I need to have for inspection? Do I need a full suit?

Also, did your guy's wheels come off the ground at the start? I have a the 16t spocket for now.

Any prefered rpm to launch at? or should I just experiment? Is a burn out necessary?
Title: Re: lets not forget the drag racers!
Post by: jeremy_nash on November 16, 2009, 10:07:28 PM
burnout, no traction wont b a problem, rpm's u will have to play with.  my local track requires long pants, leather jacket, leather full finger gloves, and a dot helmet.  to run 1/8th mile.  to run quarter, just add leather pants
Title: Re: lets not forget the drag racers!
Post by: GSrookie500 on November 17, 2009, 03:44:58 PM
Ok thanks a bunch :thumb:

I'm practicing my launches on the street so I don't bog off the line. Trying to lift up the front a little with stock spockets.
Title: Re: lets not forget the drag racers!
Post by: jeremy_nash on November 17, 2009, 07:55:20 PM
it's definatly possible, but you cant be shy about it!
Title: Re: lets not forget the drag racers!
Post by: black and silver twin on November 18, 2009, 10:49:47 PM
to wheelie with stock gears rev to 6000-7000rpm and dump clutch as you quickly roll to full throttle. worked for me every time, i could ride them too 10000 rpm in first, assuming i didnt spin the tire which happened frequently when the tire was cold. now that I have clip-ons even with full power mods and 15t sprocket i cant get the front off more than a foot and i can barely hold it for 2000rpm  :embarassed: i think i might go with 14t next time, that should do it

Are there any faster GS500's anywhere?
