GS 1000 engine in GSXR 1100 first gen frame?

It's possible to adapt the female part of a connector which uses a spade as the male part. They're usually open on one side which will let you tweak it to fit the shouldered pin on the oil pressure sender.

Good idea!
Thanks Greg

It looks very good!
Because you mentioned Pops Yoshimura, I was reminded of all the mods he made under the valve cover to increase power and RPMs. Including: port polishing, springs, buckets and shims, timing chain idler sprocket, pistons, high lift cams, all things later incorporated as standard in the GSXR oil cooled engines.
John I don't expect you to do all those things, just curious if you were able to do any of them.
Thanks.

No I don't believe I have that kind of expertise.
I'm just an amateur mechanic really and while I'd like to have this done on my engine, I don't know who could do it around where I live.
As I'm lucky to have much more powerfull machines in my stable I'll do without.

This is what I'm planning to do in pictures.
The OEM manifold as it stands

The crush washer simulating the flat adapter that will have a smaller ID to match the exhaust pipe ID

The half moon in place that will come against the adapter

I got the header back today with adapter welded into place and in no time flat I got it back on the bike.
Looks OK to me!
In fact this header would work on any GS 1000 in my view.
Last but not least there is still access to the drain plug!
The header will be painted later of course.


Plenty of space for the 18" wheel

Still the minute interference with the bottom case fins

I just bought a complete OEM Katana 1100 exhaust for my 1127 swap into a 750 Katana. Those pipe ends look similar, and the ring clamps identical.
You just might try putting an OEM GSXR or GSXF exhaust on for a fitting test. It might work.

[John Kat]

Maybe I should have read the warning before starting this project
Sorry it's upside down...

In any case there's plenty of room to shorten the wheelbase and bring it back to OEM length if need be.

To add to the racerresque look I tried to bolt on the XR 69 engine sprocket cover I got from Ozman.
Due to the rubber chain guard it will not go in without some metal grinding.
No big issue.
I also got the GSXR 1100 K front mudguard on with some spacers to cater for the 18" wheel.

I like the look of the one line/crossover brake line too.
The fact that Ozman has spare XR69 parts is amazing.

It looks good bleeding them can be challenging.

Hmmm...i have the same set-up on 2 bikes and did not have any troubles.
My take was that there was less places for the bubbles to hide.

I agree with akckhim, it can be a major pain to bleed this kind of set-up.
My ZX 10R has a similar set-up and it drove me absolutely nuts to get the air out of the system.
I finally managed to do so with the calipers lying flat on a bench to allow the air to escape.

[akckhim]

I put this over the fender setup on the cb650 project. Was a little difficult then I unbolted the left caliper held it up straight and used hand vac and that did the trick. If I was to do it again would use the two lines from the master setup.

I got the electrics to work today but learned a few lessons underway...
As I have a GSXR 11K harness, I discovered that the connector on the RH handle switch assy is not compatible.
Not to worry as it was only a question of moving over the compatible connector from the old GSXR 11 J harness ( great fun).
A few issues later, all circuits powered up with no smoke.
Interestingly enough when the neutral cable is grounded one hears a relay?
It's the device that stops the engine from starting if you are not in neutral.
This must be a modern bike for sure!
However when I decided to hook up the throttle cable, more trouble appeared as it is not compatible with the body of the switch assy...
I have two options: eitheir buy a GSXR 1100 J throttle cable or else reuse my old GS 1000 switch assy ( and rewire the connector once more!) ?
More fun ahead!

The LH footrest parts arrived today and after approximately 2 mm of milling of the XR 69 sprocket cover, both went onto the bike easily.
The chain alignment was checked with the Profi Cat laser and yes, everything is under control!
A small issue remains as the pivot for the gear lever is not part of the footrest assy, I will have to use the std gear lever turned back to front with the inconvenience of having to shift gears the other way round..
My last bike that operated that way was a Norton Commando.
Last but not least, the diaphragm/piston assy can be removed from the carbs even when fitted to the engine.

Ref the problem of no pivot for the gear lever, have you considered removing the lower bolt that holds the footrest plate & making a custom part that provides the pivot point & fixes the plate. Could be as simple as a longer bolt, a washer & a spacer sleeve for the lever to spin on. Might need a shorter lever though. Just a thought.
