Think i might need advice i bought the complete four spring clutch but what i didnt get is a thrust washer like they have on the Triumph T120`s that fits against the adaptor for the roller bearings.
Do they have one on this conversion.

HI Peter,
The "normal" 4 spring clutch does not have the A65 type thrust washer
It will only fit the SRM shaft adaptor
I am not aware if any other manufacturers have copied this ?

That`s put my mind at rest its not an SRM clutch adaptor,
Ive been watching Triumph clutch baskets being replaced on you tube , 3 and 4 spring Triumph clutches have thrust washers that`s what made me think i should have one.

thanks for quick reply

So far so good
Have decided on one tooth more on the engine sprocket 22T all lined up and enough slack in the chain to connect it all up.
I did find that the adjustment of the primary chain was hit and miss, as soon as i tightened the gearbox at the bottom mounting the chain went tight,
I had the bottom mounting pretty tight at the end to stop this happening.

Has anyone bought and used the SRM alloy clutch pressure plate with the roller bearing on the end of the push rod.

Is it worth £70

 Moto Guzzi Big Twins use a similar arrangement, tophat ~€40, radial thrust bearing ~€10...

Yes, and yes, a well made piece of kit that works very well. John

I have the complete SRM 4 spring clutch kit with said pressure plate

It's well made and fits / works well....IMHO worth the money

FYI
Some clever bloke on the forum recently posted a modification using a standard 4 spring pressure plate like yours and a Suzuki radial needle roller lift bearing at the end of the push rod
http://www.a7a10.net/forum/index.php?topic=9505.msg68877#msg68877
Not suggesting you modify your new unit but interesting way of achieving the same as the SRM pressure plate

SOP to fit somthing like that to all clutches I work on.
Some I have been forced to make mself as back then the Devimead ( now SRM ) kit was only available for A65's.
Now days you can get an alloy pressure plate for just about everything and the top hat lifter is std on everything that comes out of Japan, Italy & probably China.
So you can usually find something at a bike beakers that will fit or can be maodified to fit.'Just the top hat & bearing alone make a massive difference as the plate is forced to lift reasonably square.
Combined with the alloy plate you end up with a 2 finger clutch as you can back off the springs a long way now te plate is lifting and pressing in square.

Well what can i say
Thanks you  all the help on deciding how to make the Rocket better.
The extra tooth engine sprocket allows me to cruise at 3000 revs at a speed of 60 mph and it pulls sweetly through the gears loads of top end speed left.
The 4 spring clutch with the SRM pressure plate is so slick
It allows me to select neutral when ever i want too. Just like a modern clutch,
Just glad i binned the six spring clutch.

Cant stop riding the bike lol.
62 years old and it goes like a Rocket

Thanks for the reply.
I did until the HT lead came loose on the mag pick-up it came unscrewed,
Do i stop or get home on one, not knowing what had happened.
On one didn't want to stop motor it did happen when i was overtaking, bit scary.
old bikes who would have them.

Still grinning.
I decided it will be at Stafford show April.
