Neutral switch/gear position switch

[wraith]

Ok all, 

Going round in circles here, been told (on here) the gsx750/1100 has a neutral/gear position switch that is 35mm diameter where the rubber seal goes but everyone I ordered has a 25mm diameter?

Can someone say the year and model that has the 35mm diameter? 

Thanks

Here is the page from Robinsons for info - part # 36 inc part numbers with superceded one also.

All air cooled 4V GSX 1100 use a 36mm one  Part No 37720-09300-000  is neutral only switch as pic 

if you want gear position then its a Gsx 1100 EFE one still same size different part no

you can cross ref the part no,s on Fowlers website "not mobile friendly"  as  a few oil boilers use the same neutral switch "it is listed as discontinued though"

I,ll have a dig but the 25mm  "ish" is used on one or more 8V GS  models

26mm 2V GS one 

I you want a 36mm Neutral Switch one then i should have one

Cheers,

I'm looking for one with the gear position. I've got a couple of the ones with just a neutral. 

I was told the the earlier gsx et has the same as the efe. But they all seem to be the 26mm ones.

[Duckndive]

Nope there all 36mm on 4V 1100 ...26mm is only on 2 V engines 

If you want gear position best to go for an EFE one find the part no on fowlers the search Eblag or Google with it

Do you know it the gsx750 have a 36mm gear position one ?

never owned  air cooled 750 .... so cant say TBH 

 

[Duckndive]

there's almost every part book on Alpha Sports 

https://alpha-sports.com/suzuki_parts.htm

Just remember that in the USA    both european  2V GS &  4V GSX air cooled models  are called   GS  in the USA

I did, and it had the gear indicator, that's why I assumed an 1100 ET did also! Obvs not it seems!

Some 1100,s did   .....and off course the 1135 EFE did ....

I will start checking out Alpha sports sit.

Forgot all about that site, I used to use it all the time for comparing parts. 

[wraith]

Looking on the Alpha site, the 750 has the same one as the GS range and the 1100et is a different part number to the ef/efe 1100

1100ET only has a neutral light   , EF/EFE has neutral light and gear position indicator 

if you have an 1100ET with a gear indicator in the clocks it most likely has had 750ET clocks fitted at some point "they used to be very cheap 2nd hand" 

1100ET clocks have a bike symbol check panel  where as 750 ones have the gear indicator and there are small wiring differences

So, to be clear, are there four switch variants in total: 26mm or 36mm either with a neutral or gear indicator function?

Correct 4 different types

Do both 26mm types fit all engines with a 26mm switch recess and likewise do both 36mm types fit all engines with a 36mm recess? If so, we need a table showing 26 and 36mm engines and models that had either basic neutral or gear indicator switches. I am interested in this because I have spare EFE gear indicator salvaged from some wrecked clocks (34 years ago ) that could go onto an oilcooled bike (26mm switch for gear indicator needed???).

Yes the switch,s fit the hole...

But for it to work correctly the hole in gearbox shaft needs to be in the same position as the donor bike..

Not all oil cooled use a 26mm switch ....

early slingshots and blandits use a 36mm switch as we used an EFE one for a Nos trigger  

and to confuse even more a lot of the modern water boiled sports bikes use 26mm switches for gear position

Yep, I was holding that one back: the aircooled and oilcooled selector mechanisms work in different directions so if for example a 26mm gear position switch (from an old four) was used on an oilcooled bike, to get it to work correctly with an OEM Suzuki gear indicator (that to my knowledge were only ever fitted to big aircooled fours and some ancient two strokes), would require at least a load of faffing about with the wiring.

[Captain Chaos]

I had an 1100 EZ/ED switch on the B12 engine, to make the EFE clocks with gear indicator work. The wires in the plug needed rearranging a bit (some logical thinking helps here) and it worked perfectly.

Mmm I thought all oil cooled used the larger 36mm ones, yet one more school day  

I wonder what the gsxr1100k is, will have to go and have a look.

[GSX1100dreamn]

I used on my 82 GSX1100 a 93 GSXR1100 W switch.

So does the gsxr1100w have all the wires for the gears?  Or am I looking at this upside down 

[Dezza]

So earlier switch from GSX1100 is 26mm and fits B12? The switch on my EFE is the larger 36mm type. Like Wraith I used to think that all GSX1100 switches were the same but that does not seem to be so.
