gsxr forks for my 1150 efe

[Billy Ricks]

The guy with the Gixxer website got his info wrong unless maybe Euro models were different. The '90 models had the same front end as the '89, non-inverted.

 

[Anonymous]

Don't get an '88 front end, it was the shortest of the bunch. The '89 or '90 gives you extra clearance and the 1100 should be a little longer.

I don't intend to - the 88~89 refers to the rear wheel.
As for that guy having the wrong info, quite possible. I'll be on the lookout for a '91 front end.

I'll ask around for the 1100 front end as well. All these comments are highly appreciated, as they hopefully will save me from getting parts I'm unable to use

Here in Canada we got the inverted front end in 1990. A buddy of mine had one. I have his bike on my web site but you can't see the forks. This was just to stir the pot and to keep every one guessing.

I just put 1993 GSXR1100 forks on my 84 GS700E based project. They bolted straight on , all bearings were the same. All I had to do was make a new steering stop , as the 700 had one on the top of the frame neck , wheareas the 1100 has one on the bottom of the neck. It was all over in 1/2 hour and looks great !!

gsxr forks for my 1150 EFE

Finally I finished my bike and made some km. I couldn`t believe a difference in handling, stability and cornering.
The first time bike is not affected by strong sidewinds, any road irregularities and finally is super stable in turns. Encouraging me to do really crazy manoeuvres on the highway tonight, but I lived to write about it ))
Also makes 170 km/h your average cruising speed.
It also looks different - much more busines like. It needs better paint and a new seat cover, but this will be done during the next winter.

This was done to my GS 1150 EFE:

- 87 GSXR front end with an aftermarket brace, small aftermarket GSXR front fender, converted Katana 750 3`` front wheel + rotors working together with Nissin 4 pots calipers ( 1.2 Bandit ). Lots of hardware made to connect everything together. Original GS ignition switch converted to fit GSXR triple tree.
- Tubular handlebar installed on the top of triple tree instead of GSXR clippons.
- Front braided lines.
- 4.5`` rear wheel with rotor ( RF 600 ) working with original GS rear caliper, caliper hanger shortened, rear sprocket carrier adapted from Katana 750 ( making this wheel fit GS swingarm without a problem ).
- Chain and sprockets conversion from 630 to 530.
- Radial tires - BT 010 front and BT 020 rear.

I`ll try to make some pictures during the weekend and place them on my motorcycle page. Again thanx everybody on this forum helping me with this project specially Billy Ricks and Gerry.

Happy to have helped Adam. Being able to run radials makes such a difference in the handling it's hard to believe it's the same bike. Before anyone does major motor mods it only makes sense to make the bike handle as well as possible. Even without motor work the suspension mods make the bike quicker in challenging sections of road. The confidence the upgrades give makes it money well spent.

My 81 1100 with USD forks

My 81 1100 with USD forks

I used a 93 GSXR with USD forks on mine. I made a rear swingarm out of two GS1150 arms. I cut the single shock mounts off. Extended the arm and widened it to except the GSXR 5.5 rear rim. I do some drag racing and street riding and the bike goes and stops great. Draws a crowd whever I go. It has a 68" inch wheelbase and is just plain fun to ride. Swapping to more moder 36mm carbs from a GSXR (36mm) was a big performance upgrade. 155-160 mains (depending on where you live. Shim the needles. Brings new life into the GS motor.

Hey Adam,

The bike looks great!!!!

Nice job on all the mods for your brakes.

I like the way you modified the rear, It seems to be a simple thing to do to get the matching rims and rubber. I'll be looking to do the same thing myself in the future.

It really does make for a better ride after all the mods are done eh!!!

Adam,
I just checked out the link to your bike. It turned out awesome. Very nice, tight, clean package. You done good.

 

[Anonymous]

Thanks guys. I`m happy you liked it.
As a next step I`ll try to install Race Tech Gold Valve Emulators to be closer to your league in front end performance. Somehow my stock rear shock still works properly.
I still cant believe how good this bike started to behave - before I was holding it in line, now I can hold to it - it just rides like on rails, no matter whats going on.
It was really interesting what BigT81GS wrote about GSXR carbs and head on 1150 engine. My question is if you lose some low end with this carbs alone / with carbs and head compared to original ?
I do not race and in real life on bumpy Toronto streets this punch from 2000 rpm feels really usefull.

Unfortunatly all the commentaries are in polish.

 

[Gerry]

I think the cost involved in the gsxr head, top oiler and carbs would be a little rich for me for something that your not sure of the amount of horsepower gain. It sounds good and probably works well but for the street--------I would go with the smoothbores. They take a little bit to get used to but deliver the bottom end grunt you are looking for.

Reading between the lines (Polish ) in your blast from the past link it would seem your involvement in motorcycles has been very interesting. Great pictures, I'm sure it would be a great read.

Gerry

 

[Billy Ricks]

I think the perception you lose a little bottom end, and I'm guilty of thinking it too, is because the topend gets so strong with smoothbores. Topend is so good you get this feeling that the bottom isn't great. You just rip through the gears. The difference between CV's and smoothbores is like the difference between your stock suspension and the Gixxer stuff. Most of the time in twisty stuff I don't even use the gearbox. If you're careful how you roll the throttle it will pull from low rpm's. If you just want to do one mod to increase engine performance smoothbores are the way to go.

BTW, if I were going to have a GSXR head I'd have the rest of the motor sitting under it. I've though about doing the head conversion before, but I think I'd rather stuff a GSXR 750 or 1100 air cooled motor in the frame.

*** And what do you mean by this ???

Adam M.

 

[Gerry]

What I meant was that the smoothbore carbs work differently than the others. When you give it a big shot of gas (were talking big here) at low rpms they can bog a little and when you give it gas it has to burn all the gas that is shot in there before the rev's come down.

These carbs add something like 6-10 hp and for me anyways the bike pulls real hard after they were mounted. I mean you start to honk on it and go through the gears and before you know it your doing 180 KM and as you said that is an easy speed to ride at.

Hope this helps

- 4.5`` rear wheel with rotor ( RF 600 ) working with original GS rear caliper, caliper hanger shortened, rear sprocket carrier adapted from Katana 750 ( making this wheel fit GS swingarm without a problem ).
- Chain and sprockets conversion from 630 to 530.
- Radial tires - BT 010 front and BT 020 rear.

Adam M.

Hey Adam,

I was wondering if you could help me out here. I plan to start to look for parts to change the rear rim on my bike. I don't know if I will do it this year but I would like to get started on looking for parts (good deals).

What year rear wheel, sprocket carrier and rotor did you use? And any advice you could give me on the conversion.

Thanks in advance

 

[Anonymous]

The cheappest wheel I was able to find was rear RF 600. I got it with sprocket and carrier, but as a set it was pretty wide for my application.
Because I already had a 3.5 Katana rim with carrier, I put together Katana carrier and RF rim. This was much slimer package.
It was available to set a wheel in the proper position in my own swingarm, with caliper in propoer position on the rotor and with rear torqe link clearing my new 160 mm wide tire without any modification.
Only problem was small RF rear rotor - my original caliper was hanging too high. This was solved by shortening my original caliper bracket.
This and making of new spacers was only real work done on this conversion.
Aha, I had to trim a little ands of bolts attaching sprocket to its carrier - they were touching inner part of the swingarm. Another thing touching was a chain to bolts keeping footpeg in place, but only because my footpeg bracket was broken and later welded together.
By the way the RF wheel is an exact copy of 4.5 GSXR wheel, but these wheels were normally much more expensive on EBay.

Hey Adam,

Thanks for the info, I guess I'll start by looking for a rear 4.5" rim and see what comes with it and work from there.

When you say RF wheel I assume that is a kat model and is any three spoke 4.5x17" rim.

e-bay here I come

 

[Doze]

Actually Gerry, the RF models were not Katana's. They were an early to mid 90's sport tourer that came in two flavors; 600cc and 900cc's.
Doze. :wink:
