Believe its a k motor v711 code. Got the bugger off now though

[Swiss Toni]

I’ll have a look for a K manual for you.

1100 k has a coil spring clutch..not a diaphragm one 

[Jdeac]

What's a v711 code then???

I believe I'm ready to split. Removed all bolts and put them in some empty cases. There is a few sneaky ones. For the ones that don't know

[Jdeac]

Watch out for this little bugger in the neutral switch aswell

My understanding is that  V711 is GSX-R1100.  
 

[Jdeac]

Correct but I'm unsure what year. 

[Jdeac]

Can't remember which member said about this. But pics for whoever needs them. Small nut on the 1 bolt

[Jdeac]

Like this

[Jdeac]

Left and right selector forks to the output shaft. Middle to the clutch

[Jdeac]

Lift off. Watch out for the crank shells. 2 have stayed in the centre of the crank. Others in the lower case

[clivegto]

Haynes manual is very helpful, ti's what I followed the first time I stripped the bottom end. 

Ooppse missed the second page lol.

This is what I'm seeing. This is all being done because the bike is jumping out of 2nd gear. With @davecaraon the other end of what's app

[Jdeac]

Selectors

[Captain Chaos]

I once had an 1100L (1990) with V711 engine

[Jdeac]

I'm sure when I brought the bike dan said it was an 1100 k model. With the better cams

[Gixer1460]

Those dogs deffo need an undercut - not surprised it's jumping out of 2nd as it gets mucho abuse!

[Jdeac]

Not wanting to confuse myself as this is my first time @Gixer1460 what does that entail? I see one side is cut in a little. Be it the good side. Compared to the not so good.

1 side up shift other down shift.

Air shifter being used

Cost wise and benefit where would I be??

[Gixer1460]

Undercutting helps the dogs 'lock in' when under power and most OEM gears have a degree of undercut but when racing it can be insufficient. An engine builder / transmission shop should be able to do the work which is fairly precise to match angles between gears and around the dogs so they all contact at same time. That dog ring does seem somewhat battered / worn out. I'm not strong into gearboxes - to many iddy biddy pieces so I leave it to peeps who know better!

[clivegto]

I had the same problem with one of my engines jumping out of 2nd gear it was the dogs that were rounded of on 2nd and 5th gears. I replaced them with new Suzuki ones. I belive the gsxr1100m/n and B12 ones are slightly undercut as new.

As the K had the better "IMO" coil spring clutch   so from the pics you posted i,d say its an 1100L motor ...

Normal 2nd and 5th carnage ........The Gears on later M , N models had a better undercut on the gears ...

You can mix and match gear,s from all the 1127 & 1157 motors "well i have" i think the water boilers use the same box as well 

It's worth checking on robinsons site as the gears sometimes pop up on sale...and i've bought good complete gearbox,s of ebog for not much $$  

 

 

[inmate]

Thanks for this info @DuckndiveI asked the question in this forum earlier. Maybe I can make up a decent gearbox from used gears with new bearings.

[Jdeac]

@Duckndiveb12 stuff work?? Not seeing alot ox boxes for sale

i,ve got a mixture of B12 gears and GSXR bits in mine...

one of the B12 bearings is different and there are minor input shaft differences "length" but they can all be made to work 

Frankenstein's guide covers most of it
