Title: Acceleration?
Post by: steve on January 02, 2005, 02:59:17 PM
Hello,
i was just wondering what sort of acceleration and max speed the 2004 GS500F would give for a 6 foot, 85kg man?
any figures would be a good help.
thanks, and happy new year

Cool.
Srinath.

I've gotten my GS up to just over 110 no problems at all. I have an '01 with a decent amount of engine modes (Jets, Pods, Full Exhaust, Ignition Advancer, etc.). Im 6'2 220lbs (not sure about Kg conversion). At times if i yank the throttle it almost feels like it will throw me off (or it could just be my own stupidity). Anyways, if its acceleration your worried about, you can put a new front sprocket on there which will dramatically increase lower end power, if may decrease your top end, but not noticably plus with engine mods you can make up for the top end loss. Hopefully that made some sense :). Have a good one.

Did the 110mph include the optomistic speedo?

I was tucked in going down a hill with a long straight stretch of I77 and the speedo suggested 113 once... It might have really been 100... The bike was stock and I weigh about 200lbs without my gear and had a 15lb backpack strapped to the seat behind me... It felt like the 500f had a little more to give but I really enjoy my drivers license and backed off after a mile or so...   Keep it in the 80's and you'll love it...

I have a '04 500F and I am 6'2" about 180...

Acceleration - not much to say here...

Top Speed - I have gotten it up close to 120 with full tuck and no cars creating wind, but it starts to wobble real bad.

it shouldn't wobble...i've gone over 110mph many times...it never once wobbled.  :dunno:
Title: No wobble?
Post by: addison on January 02, 2005, 06:43:07 PM
I am a newbie rider and I don't think I have learned not to use the death grip when riding so I get the wobbles. That is the only thing I can think of if others don't wobble at higher speeds. Could tire balancing cause it, kinda like on cars?

yea, too much pressure on the bars ain't good...also make sure tire pressure is correct...

I've kept a tabulation of the test results from all the GS500/E/F tests I've found that have been published in the MC magazines since 1989.  The results have been pretty consistant except the tests for the 2001 and later model bikes show a drop performance.

Besides the major carb change that started in 2001, there appears to be a new intake camshaft number for 2001 and later and a new exhaust camshaft number for 2004 and later models.  1989 thru 2000 camshafts were all the same according to parts fiches.

I have a 97 GS500E that's all stock except for a 15T front sprocket and a 02 GS500 that's all stock including the 16T front sprocket.  The 02 feels much stronger all around than the 97 and pulls at lower rpms than the 97.  The 02 is a delight to ride compared to the 97 because of the improved flexibility of the engine.

Neither of the bikes has been rejetted and the 97 is a pain in the butt to ride in very cold weather, never seeming to warm up completely.  No problem with the 02 in the cold weather, it's off choke in a couple blocks and pulling easily without the balkiness of the 97. I ride year around here in NE OH and it was about 35F when I went out yesterday.

Here's the test results I've recorded:

Let me know if you can't open it.  I recently went back and added the test results for the EX500 just below the GS500 results in the cases where the GS data came from a comparo test between the two.

i've had my bike accelerate from 0-76.37 mph in 9.0 seconds when i was drag racing...

my bike has a heavy 150 rear tire and i weigh about 210 lbs with my gear and the best 1/4 mile time i got was 14.2 @ 92 mph

Link should open my Public folder that has 2 rack pics, 2 tire logs, and the GS500 tests.  Wouldn't work for me a couple times, but seems to be working again.  Maybe Yahoo problem?

Huh ... you think they yanked out the mondo duration cams the 89-00 had and put in smaller duration and higher lift ... Someone wanna try swapping  camshafts ... or will that make for too close valve piston clearances ...
Cool.

GSJack, the later link works but shows only the rack pictures, if you e-mail it to me I can post it from a different server than yahoo's...

Sent you e-mail with my GS500 test data collection attached.  Maybe you can display it.  The last link I posted here shows 5 items and appearantly only 2 are showing for you and manofthefield, the rack pics that are in .jpg form.  The GS500 tests and the tire logs are in .txt form.  That may be my problem.  Will try to convert them to jpg.

I had no problem using both forms with AOL, but am using SBC Yahoo DSL now.  Different setup.  :dunno:

Srinath, there is so much difference in my 2 bikes that it has to be more than the carb change.  They must have retuned the cams for better mid-range at the sacrifice of a little off the top end.  Anyhow, I like the new setup much better.

If I ride the 97 for a few days it seems like the same old bike I enjoyed for 5 years and then when I get back on the 02 again it is so much better I don't want to use the 97 anymore.  I'll keep the 97 for backup, but it won't get much more use.

I've drag-raced Danny on his 01, and it's been about equal.

He's got Jardine full exhaust, Kevlar clutch, 140/80 rear tire, K&N pods, rejetted for Reno, we're 3K feet below there, V&H advancer and with the jetting in there now has a big flat spot in the middle of the range, and doesn't pull hard till 8K when it yanks pretty well.  Stock gearing on both bikes.

I've got and 00 with drilled stock exhaust, stock air filter, rejetted (can't remember what though) and a 150/60 rear tire.

He's got 12K miles on his, I've got 8600.

Both bikes have recently undergone oil changes to 10W40 Yamalube semisynth, along with Suzook filters, less than 500 miles on valve adjustments and properly adjusted pressures/chain tension.

I believe he weighs around 230, I'm at 185-190.

Just thought it'd be an interesting comparo.

Thanks for posting this TR.  Looks like you printed my data sheet and then scanned it so it could be taken to a photo program to work on.  I used to do it that way till I discovered I could upload the .txt form to my AOL FTP space and link it.   Appears this won't work with the Yahoo Briefcase setup but I'll still persue it since it's so much easier to update the data sheets if kept in the txt form.

i'm about 170 lbs, 5'10"..... on a gs500f - not jetted yet, just a k&n drop in filter. no engine mods.

i've taken it a few times more than i wanted over 100+mph...blame it on juvenile behavior on my part.

with the throttle all the way down, on 6th gear, it tops at about 118 on the speedo.  that's with me ducking down under the wind shield.  :dunno:

acceleration wise, this bike pulls on 1st, 2nd and 3rd gear below 70mph.  anything above that, its a slow acceleration compared to a car.

You're welcome Jack. I didn't print/scan the sheet, just opened the file and ScreenPrinted and pasted on a JPG file, in two steps because my monitor only supports 800x600 mode, and uploaded it to my ISP webspace, that's it! And sure you're right about updateing, I didn't try to link it in text form.

What called my attention is the EX500 going from 60-80 in only 5+ seconds, against GS's 8+ seconds, otherwise figures look quite even.
