GS1150 Chassis mods

[johnnysuperbike]

This is my 85 1150. I've put some GSXR parts on it from 93,94 750. This is a great web site, very helpful. I got some ideas from people here and a few of my own. The bike handles great now, stops a heck of a lot better and feels great. Engine mods will be next, not sure if I should have the engine built or go with a GSXR 1100 engine. Any advice would be great, thanks.

Let me be the first to say "Welcome to the forum"\\/ =D>
Especially to one of the finest GS region.
New England.
We have a plethora of GS riders in the Northern New England alone.
We all would be more than happy to meet and help you out.'
Truly a great bunch of riders,both here and elsewhere.
I know advice will come.:-s :-D

I agree. Your bike looks GREAT Johnny!

Hey Johnny, Welcome.

How about a couple of better photos of your bike?

I'd say, if you have access to a GSXR 1100 engine, I'd do that .

 

[johnnysuperbike]

Ogri, thanks, I put a lot of time into the bike last winter, I'd like to show you some more pictures but not really sure how. I'm still a little green with the whole computer thing, tell me how to put more on here and I'll be glad to, you don't want to know how long it took me to figure out haw to put one picture on there. The thread starter said I'd reached the maximum amount for attachments....I think, maybe I misunderstood, can you give me a hand? Thanks! I also see most of you have a picture of your bike or bikes next to your name and other bikes you own listed, not sure how to do that either, as I also have a 72 Kawasaki H2

Use Photobucket.com to have your photos online. Then you can paste the URL into the Image dialogue box.

Nice looking GS.

I hope you are able to post bigger pics so we can all check out.

MY GOD! what is that big box on top of your headlamp? what was suzuki thinking????

 

[RifRafRacing]

Sweet 1150 john,looks like the 06 model if Suzuki ever made it.Will I see it at NEDW in april?

 

[johnnysuperbike]

Thanks Rif, I'd love to see everyone elses toys too, what is NEDW? Like I said, I'm new to this stuff.

 

[johnnysuperbike]

Fern, I'd like to show some more, bigger pics, still having a hard time with figuring out how, not real good with computers yet, I tried the photobucket thing but still can't figure out how to get the pictures here!

New England Dragway in Epping.You gotta give that bike some exercise.

I would build the 1150 motor, there are tons of aftermarket parts available for it, and it would look better and probably make more power anyhow. My 1150 had a 1129 kit G-4 cams mild head porting and rs 38 flatslide carbs. It had stock chassie, The stock tiny 130 size tire and still ran a 10.34 at 136mph in the 1/4 . with nitrous it ran 9.97 at 148. It was very streetable and after I sold it the new owner took it on may trips ( as far away as NC and piled all kinds of milage on it.

Skip, even two years ago I would have been with you 100% but it's seems this is no longer the case. Let me give you a few examples. Wiseco does not make near the selection of pistons for the GS1100s that they used to and only make a couple for the 1150. In my case, they no longer make any turbo pistons. Last year I was talking with Cliff and it sounds like they may be the only ones making aftermarket blocks, if not today, then very soon. Even some of the small parts I used to be able to buy from compaines like PMFR and Star are no longer available within the last few years. Parts that can still be purchased, like the streight cut gears for example have gone through the roof in the last years or so.

I think the writting is on the wall. There is not as high a demand for the GS parts, let alone the 1150 and the companies who make the performance parts know this. Any catalog I get now does not show GS aftermarket parts, they show Busa parts.

Just a few years ago if you went to any major pro race, compaines had GS parts on hand ready to sell you. Go to a pro race now and what do you see, Busa parts.

As far as the power, I doubt that the 1150 made much over 120HP. What's a stock 600 now days put out? Plus its much lighter. Why try to make a tank into a Corvette, when you can buy a Corvette? For that matter, just buy a Chevy, it will still outrun the tank and not cost near as much as the Vette.

All good points, I stand corrected :-D

:sad: While I know you are right, I'm in denial[-( ! I love my tank!

Thanks for the advise guys, I guess I'll have to see what the difference is between the two compared to power output and parts availability. I have a couple options for people to do the work, as I'm not an engine builder really. The chassis work was fun and not too frustrating but I've never built an engine before. I used to live in Vermont and Bob Moshinski did all my work for me then...very experienced with old Suzukis. That's what he used to race. I don't know if you guys have ever heard of him or not..."Moshinski Performance" Also, I live about an hour from Ricks Motorcycles in Plaistow,NH. I bought a few parts from them when doing the chassis work. I"m sure they'd be able to do the motor or the engine swap for me. I'll have to look into both. I'd love to get down into the low 10's or better, I only managed 11.8@115 the last time I went down. I've only tried Epping 3 times, so I guess that's probably not too bad? Sorry Rif, I felt stupid about the NEDW thing, just never seen it abbreviated. Sometimes I need things spelled out for me!

 

[lecroy]

Those are some real good numbers! How much do you and the bike weigh?

My tired old 1100 only runs in the 12.20s or so at 108 with 220 pounds of rider and gear on her. I had it in the 11.90s year before last but it was a fluke. Good wind.

 

[johnnysuperbike]

Lecroy, thanks for the advise. Are you saying go with the GSXR engine? When I made the 11.8 runs, I still had the little 140 tire out back. The engine is a stock 1100, ya..1100. Long story short, I had an 81 1100E, Bob Moshinski had the 1150 with the engine yanked out for some guy for a sprintcar..too bad, he put the package together for me back in 95. The engine has a stage 3 jet kit, K&N filters and a Propipe, back then I had a Kerker megaphone. I'm thinking I could probably do a little better now with the 180 on the ground. Also, I weigh 210, the bike weighed 515 with about a half a tank on the track scales. The engine also has 43,000 miles on it, still runs OK but definetely a little tired. I guess what I'm looking for is reliability more than anything. The bike has been the most reliable thing I've ever owned. I just want some more punch out of it and still be able to go on 200 mile rides.

I would stay with a GS over the older GSXR engines if that was the only choice I had. I own a 94 GSXR that I bought new. You don't see these many of them at the track for a reason. The GS crank was hard to beat.

If I were building something new, it would be based on a newer Busa engine. They have finally found a home at the track and parts are out there for them.
