Taking into consideration I put a new SRM complete clutch assembly in last summer and it sat throughout the winter months I am wondering if the oil has got between the plates and is causing drag. It seems to be a shame to pull the chain case off again, but needs must. Just thinking out loud ( on the keyboard ).

G'day JWO.
That's possible but i would think SRM use friction plates that are resistant to oil like modern wet sump bikes. But in saying that my XT500 only gets ridden a few times a year and after a few months rest the clutch is gummed up that much I have to start it in gear and ride for a mile with the hand lever pulled in till it frees.
I keep looking back at your 2nd post " The whole box was cleaned and inspected last year." and wonder about that.
Cheers

Stripped the SRM clutch and bathed it all in petrol. Was not really covered in oil. Re-assembled and took it out. Same problem, could not select first after going up the gears. On this clutch I had to shorten the push rod to accommodate the clutch pusher / top hat bearing. SRM advised adjusting the top hat by taking up all the slack and then turn back a full turn before locking. Going against their advice I took up the slack and turned it back 1/4 of a turn ?. It worked and I now have a fully functional clutch and selects all gears with ease. I am obviously pleased but would like to know why this happened when it was fine when I built it last year. I have only done 5 miles since restoration if that helps. Thank you for helping me with a non A Series bike.

G'day JWO.
Did you clock the pressure plate lift with a dial indicator or similar. Even with the SRM top hat pusher the springs need to be adjusted to give even lift.
Great your getting somewhere.

It all looks even and works nicely. All buttoned up and new oil, now have a lovely gear-change in all gears. Thanks for replies.

Followed SRM instructions at first, didn't work. Took up the slack by 3/4 turn on pressure plate. So in fact is now a 1/4 of their recommendation. Rang a guy at SRM, was helpful and told me to leave it as it is. Possibly took about 5 mm too much off of the push rod. ? Enjoyed the thread  *eek*
