Think I saw this bike at Brooklands a few weeks ago, from a distance it had me flummoxed. The chap who was showing it was very knowledgeable and brought it home to me just how little I know about them. Ref gs into gsxr frame as was the original question I say thank God someone does or we lose the talent involved. Viv OSS.

Many thanks, I'll have a look at mine and see if that matches.

Does anyone know if GS750 & 550 seat hinges are significantly different? I have a 2/4 seat on my '78 750 that sits about 3/4" higher than the tail piece. The hinges don't seem to be available other than with a new seat on CMSNL & I can't see how else a gap that big could be caused. The seat is marked as fitting 550 & 750 but does say "Minor adjustments may be needed" Thanks.

Is this it?

I've done the sticker bit & tried a gps speedo but want it looking OE & roughly acurrate, I'm not sure if the amount of dirt I found between the magnetic drive wheel & the driven wheel would make it lose traction & hence read slow. I'll scrub it all clean & see what happens. Thanks for the replies.

I've got it apart trying to find out why it's 5mph slow and there's no damping in the needle. Other than a bit of dirt I can't see anything broken or not working, have any of you gentlemen had success servicing one of these? Thanks.

This is how I did it & it works 100% although not the cheapest way to get a GPI installed: The above part number is a 36mm switch & fits but it is designed for a selector drum that rotates the opposite way to the GSX1100 & it has no reistor fitted for what is now the 3rd gear position. I opened it up & soldered in a 15kohm resistor as in the pic & then fitted a Healtech GIpro from a DRZ400 that uses the same selector drum rotation direction as the GSX. There's a bit of wire relocation involved which I'm happy to share if anyone wants to go down the same route but the GPI works instantly & accurately.

Does anyone know if a later gsxr 600/750/1000/1300 uses a 36mm switch with resistors? A Healtech GPI can work with them.

Mine look the same length, oh well back to the drawing board. Thanks for your help.

Finally, it's a rh thread 2mm bolt.

Great thanks, I'll go and measure mine :-)

Many thanks :-)

Does anyone have a workshop manual to hand & can let me know the fork oil level for an 81 Kat 1100? Thanks.

Good question! Don't know

Can anyone measure the tiny trip meter reset knob retaining screw for me? It seems to be unavailable from Fowlers etc but it's just a tinly little screw so should be easy to buy if I know what size it is. Thanks.
