This is exactly what I did !!!!

But I really want to use my Ransom Machine Works AL cover. But I need to have about 1mm machined out of the inside in order to clear the old S3 weight. Just need to find me a local machine shop.

Now why did you lay that pretty thing in the dirt??

I wouldn't take any off the weight without having a shop do it or if you have experience. These are balanced from the factory and it wouldn't take much to un-balance it with a home made file job. Then your looking at more serious issues like blowing crank bearings. The nut wouldn't be so much of an issue to take a little off.

The flywheel weight is made out of mild steel or a soft alloy.It mills very easily.As far as doing the work in place it depends on skill ,tools and comfort level.
If you want to get technical machining wise,milling the weight down a little in place on the axis it actually spins on will be more precise weight distribution wise then milling it down on a lathe and bolting it on,keeping in mind you are simply cleaning it up a bit as opposed to true tooling work.Its easy,we have done it alot.Not for clearance purposes but to get the weight exactly how we want it.

Agree. I only took a little bit off the nut as I did not want to install 4 gaskets....

Its tricky,no doubt.Some sketch hoping you don't get you or the tool sucked up into the case,or your face or maybe into the wall or maybe a random person.We also drill to shave weight.Taking the corner off is easy enough,and will not change the balance at all.The nut can be taken down in a different manner.

Stu,have you any idea how much thread you have left before you reach the bottom where the flywheel seats on the crank.And how much material you have left in the flywheel.Might be easier to take down the recessed area where the nut and washer seat against the flywheel.

Kill two birds with one stone,after looking at the pictures seems you guys are getting between 1/2 and 3/4 thread on that nut with some nut sticking out past the face of the flywheel.Follow?

I figured it wouldn't be right if this topic wasn't on the board at least once a day.... :-)

Thank you for the input and ideas I am gone this weekend but will get back to you on Sunday with some dimensions

That's kinda funny,considering the love I have for this weight.

Theres gonna be a "how to weight your clutch basket" thread coming soon.Im fishin all the time but when I get a chance to build this 200 engine Ill be putting some weight in the basket,and have some pictures and blow by blows and such.Its very effective on the small bore woods racers when done properly.

I finally had time to get a photo today... I don't know that this looks any different, but I still don't think that it touches the inside of the stator cover at all....

If it's touching you want to look at the outboard side where the flywheel nut is.
