Cable clutch and lockup ??

[latheboy]

Well hallo, 

I have fitted an 1100 coil spring clutch to my 750 and have a cable clutch.

Everything is going good but I'd like a lockup on it.

Has anyone done a lockup with a cable from a 750 actuated on the clutch cover? 

I know I'll need a MTC spacer but it's the longer rack pin I'm not sure about.. 

Is there a longer one out of a different model or do I have to make one? 

Thanks.

Is it turbo build if not you don't need lock up.

Never seen lock up done with 750 actuator it would have to be some special to work.

[latheboy]

Yes turbo. 

That's why the 1100 clutch cause the aluminum basket isnt up to the challenge.

Quick shout out to the mod who moved this for me. thanks.

Thanks @Reinhoud

I've never seen one so didn't think they were made by anyone..

 

[jonny1bump]

Something I've learnt too.

Seriously? You weren't aware of probably the most used motor in drag racing used a lock up! This is the engine it was first used on. If you need an extended rack for a 750 it's likely to be DIY!

I think he wants a lock-up clutch for an engine based on that from an oil-cooled 750 slingshot but with a clutch basket from a GSXR 1100. The link above is for a clutch kit for an air-cooled engine, which obviously will not fit an oil-cooled engine. If this is incorrect then please ignore .

[Gixer1460]

I get what the OP wants, it was the errant reference to the GSX engine I found weird! Just because it has a cable clutch operation doesn't mean 'its' extended rack would fit or work. If it was me, i'd use (and I did x2) a hydraulic clutch (for which lock-ups are available) - its not as if you have to be subtle when a turbo is involved!

Making a one off, hardened and ground extended rack for a hybrid 750/1100/cable/lock-up will likely cost what the whole clutch is costing - just sayin'

What do you mean with the rack?

You are joking right? I'm sorry I'm not up to speed with all the dragbike history to date. 

 

I have a full machine shop at my disposal and it is a quite simple part to make.

I just wanted to save myself some time and see if anyone had done. 

Thanks anyway mate.

Picture to show the difference between standard rack and lockup one also gsx1100efe lockup clutch next to a  gsxr1100k lockup clutch.

See Clive's post above A lock-up adds height over the clutch so the cover needs a spacer which then requires an extended rack piece to maintain clutch operation.

Spacer picture on my efe I also extended the actuator arm abit. 

[jonny1bump]

Clive you really have got everything haven't you.

[latheboy]

That spacer looks a bit thinner than a gsxr one. Don't know if the rack would be long enough for what I want to do.

Thought so, wasn't sure.

That's all in that kit

[Gsxrsam]

The rack extensions are 60-70 quid... spacer is about an inch thick.
