Title: Suzuki clutch
Post by: IVO on 25.02. 2019 13:46
Hi All,
I'm a newby here with the A10 disease and am looking for some one who is doing the Suzuki clutch mod. I'm in Perth and am wondering if Colin Tie still doing it or is some one else doing that type of clutch mod? After 35 years it has to go!

Cheers,
Ivo

Hopefully orabanda will see your post soon. He is the one that would know over there.

Now get over to Intro's https://www.a7a10.net/forum/index.php?board=13.0 and tell us how you got this disease.

Hi Ivo,
Colin isn't making any more clutches; he has sold his lathe.
I only make them for my own needs, but can give you some info / tips if you want to do your own thing.
Alternatively, the Triumph 4 spring works well.

Thanks for the speedy reply men.
I generally try do my own thing but that's not always been successful ( message to self here ) hence the need to seek advice! Are there any things  to beware of when purchasing one ? Just been looking at the SRM one.

I have the SRM clutch in my A10

Good quality kit that operates well

I would have thought that a clutch for a vintage Suzuki would not be such a cost effective option these days, but then the one from SRM ain’t cheap I know.

Hi Cyclobutch and All,
The attraction of Suzuki and other modern clutches is that they can be bought very cheaply from breakers and eBay
I bought a box of GS550 clutches for £50   *smile*
A blank sprocket probably another £20-30 , a bearing £10-15, and a 4 spring shaft adaptor £40-50 and some time machining and fabricating

All that said I still have not gotten round to completing the conversions I have bits for*sad2*

It is most important to get the shaft adaptor machined 110 % true to the gearbox shaft taper
I used a spare gearbox mainshaft clocked up ina 4 jaw chuck to centre up the adaptor
I also have a splined mainshaft from a plunger box and a GS550 clutch centre spline opened up to suit

Hi all,
Is the GS 500 clutch the same as the GS 550 clutch in its suitability for a conversion? They seem to be more locally available.

The GS500 is the better choice; easier to adapt.

I'm going to have a go at doing a suzuki clutch adaption orabanda, are you able to give any tips ? I have access to a lathe and can machine but will need to get the centre hub splined. I assume you use a standard 4 spring adaptor? Hopefully one of the local wreckers will have a suitable donor clutch.

Hi Ivo,
You might find them easier  & cheaper on ebay.
Send a PM and I will provide my contact details.
Where are you in Perth? I am in Maida Vale.

HI Ivo,

I got Colin's last Suzuki clutch conversion kit, in 2017. Thanks, Orabanda - for your help, about it, again. It works, still, like a dream. So, the concept is good - much superior clutch design..

Hi Richard,

I'm planing to convert a Suzuki clutch for my A10! Maybe you can help as I have some questions! Do you use the 4 spring chainwheel and how do you fix the bearing?
