Cmon man!...474 lbs 110hp but dosn't run 10s?????????????????????????????

Redman- Hello! I Congrats on retirement! Sounds like your enjoying it. Ive been plagued with spinal injuries and surgeries. Discs bulge without warning and surgury ensues. S o my last 3 summer riding seasons have been cut short. Awesome your doing well.

Jedz- that Triumph is a beautiful bike. Really strikes that 60s British look. I admit the torque and sound of a parallel twin is very fun. I had a restored semi street tracker XS650 and it was very enjoyable for enjoyable country cruising. And- as I have mentioned the Triumphs do a fantastic job of making the engine the visual centerpiece.

Griffin you potsed a fantastic write up. That is what I was looking for! I learned alot from this. I have saved your post and printed to paper. These things need to be known. I read the 3 way shootout of the 1100s and the GS had usable linear torque where the others had Power coming on much later RPM engines.


My 80 XS650 I fixed up.

We posted new posts at the same time. See the post I just did right before yours, comparing all four years' GS1100E models.

Funny how almost 40 years later, the magazines' 1/4 mile testing is still starting arguments.

Very interesting, back in the day I was riding an "80" 1100E, & the fastest stock bike around my area. Every yr. my buddy & I would study the dealer shop manuals, to find the new tweaking the factory had done to the big 16V GS engines. There were very few changes, that we could find, thru these 4 yrs. The opening on the air box changed most every year, Cams, cam timing, valves, valve seats, jets, all were the same, till mid "82", when they changed the ex. cam profile slightly & beefed up the end of the crankshaft. There were 2 "82" GS1000SZ Katana's sold in my area, we quickly found they both were about the same in the 1/4 mi. as most 1100's. We started trying to figure how this was happening & discovered the valve seats on the Katans's were cut on a different angle than the 1100's valve seats, & the Katana air box had a little rubber boot (snorkle) installed, Oh yeah, I think the "82" Katana was the first that came with a foam pre filter (or sock) over the main air filter. Were there other changes I've forgot or never knew about for the big 16V engines? Also wondering about those HP & torque charts, slightly different cam timing settings, a degree or two, from the factory could account for the slight HP & torque readings on the chart, even if the actual specs hadn't been changed.

Very interesting dyno graphs. I gotta believe the Japanese designers had a ball designing these inline 4 big displacement bikes. The bikes designed for use in Japan were not big powerful musclebikes- and giving the designers and engineers permission to go wild for the American market had to be awesome.

Damn good readings guys.

Norm awesome idea to keep the fuel flowing to all the bowls... I read that and laughed. Awesome idea.

Back in '92 i had a '83 cb1100f that was a wreck turned into a small slick wheelie bar bike. v/h sidewinder, cams and 29 smoothbores. Ran best of 10.19 a bunch of times. Currently my son has a '04 gsxr1000 with a stock motor, sidewinder and billet oil pan so it can be as low as possible, six inch longer swingarm with DOT slick with no wheeliebar, multi stage lockup clutch. 9.48 best so far. The 1000 is much easier to ride and is more consistant. My '83 gs750es with an '89 gsx750f motor runs 11.90's in street legal trim, stock motor with pipe and jetting with a DOT slick. All 3 have (had) air shifters.

All very interesting info and good on you for competing on the track!
Just wondered why you never put GSXR cams in the GSXF 750 engine?

 

[Guest]

I have a set i'm saving for the 1052 motor that i'm gathering parts for. BTW one of my sons' street bikes is a '90 gsx600f that we put a 1127 in this past summer.

 

[rphillips]

From a 600 to an 1127, ain't that a lot? It seems you would be able to watch the pistons, going up & down, from the outside.

I am not a drag racER, but I love to drag race. Even all by my self. Love the pull, and the thrill of hitting 130 or so in a few seconds, lol. I ride a '95 GSXR750W these days, and love it. It's a little rough on my old back, and hands, but it is so nimble, and freakin' fast. This past spring I had gotten stuck behind a group of cars across 2 lanes for a few miles. when I finally got a chance to get passed them, I was at about 120. Looking ahead of me, there was no other traffic for as far as I could see. So... In full tuck, she tops out at exactly 160 with stock gearing. My ol' GS will be back again someday, I do so dearly miss it. Until then, you couldn't PUNCH the grin off my face after getting off my 750W. Plan to take her out to U.S. 41 drag strip next summer, and get a few passes in. I like numbers. I also like smoking modern litre bikes through a couple gears. They start to close the gap when I hit about 110, lol.

WOW!!! I'm with you, cept I don't risk my drivers license.
Michigan cops are sent out to collect revenue from speeders, they stalk all the best highways on weekend mornings, but they're too busy when the highways are busy so that's the best time to play with top speeds.
Those mid-90s GSXRs are very cool!!!

 

[Spyder]

We ride into southern Michigan often, but usually, keep the aggressive riding down up there. The roads are just to bad. Highways aren't too bad, but we do see a lot of cops out and about. There are a lot of nice scenic curvy roads up there but in such bad shape it's literally painful to ride them, much less ride aggressively. I try to keep my hooliganism closer to home. You get to learn where the safe spots are on any given day and time, ya know? I love my '95 GSXR. All the younger kids that ride with us on MUCH newer sport bikes can't believe they have a hard time keeping up with ME, lol. And I'm the oldest one in the group ! ! !

Well, FWI the twisty roads can be found in the hilly grape growing area, LaPorte, Buchanan, Baroda, Berrien Springs, Niles and St. Joe.
I have a few favorite loops around, between and through those towns.

We swapped the whole motor. Only drawback is that you have to lower it down to get the valve cover off, luckily its a shim style so once a year or so...

We are in the Niles, and St. Joe area periodically. Earlier this year I was up there, and the roads were terrible. The patches that patched the patch that patched the patches have pot holes in them, lol. It was very disappointing. The ride to Silver Beach Pizza isn't bad. I plan to take a couple rides up along the lake shore next season. My group tells me its a really nice scenic ride.

The road crew did their training here.

Hey Spyder you sound like your skilled at launching and drag racing. I am not but I do love the sound and thrill when I max the throttle and go thru the gears on my 1100E. And enjoy seeing a bikes max potential in the 1/4 because even though I cannot duplicate a pros time I still like to see full potential. I started this post and I would love to see a pro or even a highly skilled amateur run the new 900RS.

You'll want to hit M-22 along the west side of the state along the Lake Michigan shoreline, it's a pretty decent road maintenance wise with lot's of curves and hills.

Right, and mo-fasta mo-betta!

 

[Spyder]

HA HAA ! ! ! Well, I am most definitely no pro. In fact, I am likely still barely novice class, lol. Don't really know how good my reaction time would be, as I haven't had a bike at the strip, yet. I just love the thrill of getting past 100 as fast as my bike is capable of getting me there. I do love carving up the twisted roads as well, but that gets pretty sketchy here in the midwest, with all the critters, and unexpected road debris. For the most part, I hate "leading" through the fun roads. Unfortunately, I don't commonly ride with anyone willing to dig into them the way some of my local(ish) GS brethren will. I had the time of my life down in Brown County a handful of years ago. Can't wait to get my GSXR down there. I'm just an old adrenaline junkie, always looking for my next fix.

I don't remember that last time I saw a pot hole. I believe they are extinct in my area. lol Unfortunately, road debris, gravel and sand are common. eh eh
