Help identify this clutch

[lecroy]

Here is another shot from the rear of three baskets. Top is a beefed up GS1150 basket. Right is the beefed up stock GS1100 basket with the weled in tangs. Left is one of the MTC parts.

Notice that the MTC part is welded up. The is because I had John do this one for me, not MTC.

My other MTC basket is not welded and the backing plate is a little different design.

I had one from Star at one time that was also billet. This one had STAR welded into the backing plate. I may still have that thing tucked away. This one is also a natural color.

Forgive the poor edit on your photo Bruce but you should get the idea. Those radii details would be extremely difficult to duplicate by machining a block of billet.

[Nessism]

The ones I have are very smooth with no casting marks. They all appear to have been shot peened or something on the inside. The two I have from MTC are both plated. The Falicon one I have is a natural color. All have SC gears. MTC with MTC gear and Falicon with Falicon gears. My friends sliders are all MTC. These are all coated black. My MTCs are not sliders and both are a very dark green color.

The MTCs are in the two engines right now but I took a closeup of the Falicon for you looking at the inside so you could see the texture. Hope this helps.

Yours could be billet, I can't tell from the pictures.

This photo looks like a casting too. Those curved radii would be very hard to produce through machining.

[lecroy]

You would have to call them to see what they use to cut them. The gears I have that are billet have much tighter curves than the baskets. Sharp edges and high stress don't get along.

I looked over my pictures to see if I had anything that showed the inside of the MTC with that sort of close-up. Nada. Maybe this weekend I can take the camera to the shop. I am sure the slider is cut the same as the normal one. We will have some on the shelf, easy to get to.

Jay would be a good source for this info but I don't know if he has the time or knows how to use a digital camera to get a close up of some of their work. How about it Jay?

[Big Jay]

When I said a casting, I was referring to the one on the orange chair. The one in the first photo is a forged basket. From the looks of the back, we may have built it.

I finally got my little cushion installed behind the clutch, but I may have another issue?

I noticed that this basket is a bit taller around the outside parameter than the stock one. It comes very close to the casing. I have about 1mm clearance. It still seems to fit just fine, and I don't see how there can be any play in the basket, but wanted to post these pics and get your comments. These first two pics are the aftermarket basket:





and this is the stock one:




Not much clearance in the stock one either, but more than the aftermarket one. It looks like I could shave a bit off the casing if I need to. Does anyone forsee any problems?

[lecroy]

Looks fine to me.

The baskets will have play in them. Well, at least with mine, you have to shim them to get the right gap. But nothing like what your showing.

You did a nice job with the goob. I never take my time cleaning it up and always too much on. It looks good!

mystery clutch

i ran across the same clutch in a yoshi engine of 1978 vintage it has 5 heavy springs and is welded as yours is . i would take a pic but it is in the bike and performs very well .as are the rest of the yosh goodies like the hi volume oil pump cams and head.
the disks and steels were the same as yours . might it be a yoshi hipo part from the boys at suzuki.

What are high volume oil pump cams?

What are high volume oil pump cams?

I believe that should read "high volume oil pump, cams, and head"

But that's just me...

It's the NEW English; leave out all the caps, spaces between words in the proper place, and punctuation marks.

If you ever take the cover off, shoot me a pic. And thanks to the info.

I trimmed a tiny bit off the inside of the case to give it some more room in case it does move a little. I only had about 1mm of room, now I have about 5mm.

Hey Bruce, nice basket you got there. I ran an MTC forged basket for an 1100 in my GS1000 drag bike back in the day, and it was so tall I had to trim the basket down just to fit in the cases. I cut the case back as far as I felt comfortable with first.....Anyway, rule of thumb is to have twice the thread depth (in aluminum) as the bolt diameter for a good grip. Be very careful when you tighten that one center bolt at the front as mine always leaked a little oil there as I was afraid to tighten the bolt much, and there is not enough room to install a heli-coil...Been there and done that...A dab of sealer may help.......Billy

Good job Bruce! Looks good.
If I had some time off I'd love a road trip to help ya. I bet we could get that puppy together in a day.
Teamwork.

[first timer]

Couldn't you just run a gs1100 basket that is trimed down, say about 3/8" or if you were tricky with a cnc machine make a spacer?
