Im about to put the trans in, but before I do I need some clarification. I have the twindisc that came with the new master cyl. It came with no literiture at all.
I have heard from some that 0.050 needs to be removed from the pivot ball. the way bruce's car creeps is a testament to this( you also need a hammer to get it into reverse sometimes, or just shut it off) But bruce's is one of the first twin discs and didn't come with the new master.
I have heard from others that the new master alleviates the problem Via a differnt bore size. Since California isn't awake yet, does anyone have a definitive answer for me?
I just used a pivot ball machined .050. Mine works great. It also came with the adjustable master cylinder, but I thought I would try it with just the machined pivot ball and stock master cylinder. Now I have a back up master cylinder when my stock one wears out.

If you purchased the twin recently and got the Mcleod master cylinder with the kit. Then machining .050" from the pivot ball is no longer necessary. This is what Red at Mcleod told me when I got the last two street twins at the first of this year. Both were for LT1 engines.
Alrighty, I'll take your word for it. IN ThAT CAse he heh ehe hehe eheh I get to Put the REST TOGeHTHER!! AAKAAHHHH (runs out of the house in frantic excitment/sheer lunacy. Neighbors run and hide)
On the previous generation Street Twins the pivot ball did have to be machined .050"; from what I've heard (and Tom's backing it up) is that this no longer needs to be done when their adj. master cylinder is used. But, just to be on the safe side call McLeod and talk with George; additionally get him to FAX you installation instructions, they should've been included with your setup. They are VERY adamant about ALL facets of their instructions being followed to the "t;" do it and you'll never have an issue that McLeod will not rectify. Since they are so adamant about it that's what surprises me about no instructions being included. So call 'em and get 'em.

Remove the counter weight on the flywheel. Your motor is internal balanced and you need to remove the counterweight. You will have vibration problem if the weight is not removed.
