Nice.  What mods do you have done to it and what times are you running on it?

I bet those knee sliders came in real useful during your runs.

Mods done by PO:

K&N pods
Rejet
Street stuff removed
Progressive springs in forks
Aftermarket shocks

I added a superbike-style handlebar

Running 15's. Best is a 15.3. worst is a 15.9

Well...The dragstrip is part of the roadcourse at IRP. In fact, our pit spot was right on part of the roadcourse.

Cool.  I wonder how the magazines say they get in the 13's in the 1/4 mile with stock bikes when everyone I have heard of on here with modded bikes are in the 15's?

Not to put down on anyone on here, but I was just curious.  That page with all of the different numbers from several bike mag reviews that ha been posted on here had almost every run down in the 13 second area.

2 reasons:

Rider
Correction factor.

The mags use an experienced rider and allow multiple passes. The rider is typically experienced at this test and can usually get very good numbers.

Also, the mags use a correction factor against the actual time. The correction factor adjusts for temperature and altitude. As air warms and/or is higher in altitude, the less dense it is. The less dense, the less mass of O2 gets in the engine, the less O2, the less power. So, if my pass of 15.6 is at 1,000 feet ASL and at 90 deg F my corrected time would be approximately 7% faster or 14.5 secs.

Hope that helps. There is a better explanation in the Aug '03 issue of Motorcyclist

OK.  I didn't know the 13's were "corrected" times.  I live in south Louisiana, about 6 feet above sea level.  I need to wait till a cool front comes through in November to get the best times, I suppose.  

I went to the NMCA finals in Memphis a few years ago.  A cold front came through on Sunday and everyone was breaking out of their brackets by almost a whole second when it got cooler all of a sudden.

Add to that gearing and tires.  Going from street gears to "deep" gears and slicks can cut a second and a half off a car's time.  I'd imagine the same is true for bikes.

GREAT PIC, GREG!!!

Remeber it harder to run 13's when you have to start when a light tells you. When a mag tests a bike, timing starts when the bike first moves, not when a christmas tree drops its lights. I have run a 13.9 on my GS, and so can you.  :cheers:

Isn`t it a good old 450 and not 500 and that can make a big difference... or am I missing something here  :roll:
Those about 14sec times in mags are for 500cc GS and not for 450cc one I suppose?

Toenis,

Yes, I was racing a 450. Yes, mag times are for the 500. HP difference between 450 and 500 is minimal but would probably affect times somewhat.

I was using my times to help illustrate the example of corrected vs actual and was making no claim as to what a 450 can do in the right hands.

The GS450 was the bike that got me into four strokes...

When I got my permit I was racing a Suzuki GT380 (two stroke triple) and had never considered a "non-two stroke".  I used to ride around with this group of guys on the weekends and two of them had GS450's with Supertrapps.  Those bikes were so cool man...  I loved em'.

When I saw my GS500E and recognized the motor I knew the bike would be solid and capable so I bought it.  Haven't been let down since.
