Another year - another clutch!
The VTX clutch really SUX! Last year, after using the MTC clutch, the dealer convinced me to use the stock plates with Barnett springs, it was OK for about a month....
Now I have a 10-disc Force-One to try (installing now)
Note the cooked disks (right is outer disks). As I recall, someone mentioned a lack of lubrication....

i replaced mt stock clutch with a mtc with shims now for the last year when the bike is cold and put it into gear it bangs into gear,i think i should take out the shims,how long did your clutch last
Might it be the OIL? and is it for a wet clutch?
No matter the case sorry about your luck.
There are a few things that will cause a clutch to fail; wrong oil, no shims on an MTC, factory clutch is a POS etc. MTC's bang when cold because the plates stick together. If you rock the bike in gear it'll break them loose ahead of time or start in neutral and work the clutch lever a few times to get oil in there and they'll seperate. The MTC or Barnett are good clutches if installed correctly. You won't like the 10 disc clutch

Shimmed according to MTC (called them). Is there a reason for 2-3 discs to be blue?
Lasted 900 miles. I believe I used 3 or 4 shims per spring (I was told by MTC what to use) and Bare agreed
Agreed here. I replaced mine stock with MTC a couple months ago and I used the light shims. Figured they were to be used for a reason. I'm very pleased with how mine grabs. You DO need to break them loose first for sure.There are a few things that will cause a clutch to fail; wrong oil, no shims on an MTC, factory clutch is a POS etc. MTC's bang when cold because the plates stick together.

I got a 07 f was just reading the new mtc dont needs shims or am i wrong
Blue steel discs is usually from slippage. I forgot to list that some folks had issues with levers not fully returning and allowing clutch to slip. I've installed a bunch, prolly 15-20 and never had an issue except sticking plates.
For the F guy, I just installed 2 in the last week and they had shims in the kits. I usually shim to .095 or more and also use stronger bolts

I got out the stronger bolts dont dont kn how or what shims to really use
I'm at work otherwise I could measure and tell you which ones I normally use. I want to say I use 2 thick and 1 thin on each post before installing the springs.

Blue
+1 the blue is from slippage. I would be very curious about the pressure plate stroke your getting (getting a clean disconnect). Also look the drum over really close for a spot to bind the friction. If the plates were in the right order it is weird that the stack slipped in the middle.

I am getting ready to order a new clutch and have decided on the MTC but what steels should be used with it?
Steels
I'd go with the Honda steels. They are well made and have the dimples for oil.

Jon:
The stack height of the removed clutch is 44.50mm (1.751"). What is standard?
I had a perfect disengage (no creeping at all, easy neutreal).slipped in 2-3-4-5 gears
Replaced fluid (vacuum flushed).
Jon, is it normal that the slave cylinder pushes out on it's on? I pushed it back in (was a bit hard) and it came out in a minute again. I would've expected it to stay in (slave that pushes the pressure plate)
TY
It was advised to me to use a shim. I didn't want to over do it so I used the light shims. The stock sucked with no shims and honda springs so I figured with the stronger springs and light shims that came with the MTC would put me at a "happy medium."
You put the shims on the inside or outside of the springs?
Are you sure you don't have your master cylinder too full of fluid? If you do, the longer you ride the fluid heats up and if it has no place to expand to it will start to apply pressure to the clutch.
As far as the bluing on your center steels it has to be lack of oil. All steels are in the same slots in the clutch pack and can't slip independent of the other ones. Same goes for the friction disc's, except that they are in the opposite slots.

After installing all the discs, install the cover plate, then slide the shims on each post. Then install springs, washers and bolts. TOrque to 108 inch pounds

The pushrod will creep out without anything to hold it. Once assembled re-bleed the system. I don't have the stack height but might have time when I get home at midnight to measure it. It shouldn't have slipped at all. Something is wrong somewhere. What levers do you have?

That's an interesting observation. I know when I changed my clutch and brake master cylinders they were filled up all the way with the original fluid and I got them refilled as much as I could with the bars turned like the manual says and the master cylinders as level as possible. Anybody ever hear of this?? Now I'm slightly paranoid that I may wear my clutch prematurely.
I was thinking maybe the inner plates burned due to lack of oil. I've seen the procedure for drilling the clutch basket to get more oil to the inner plates. Maybe the op drilled his. Maybe it was a case of low quality discs.
That's what I thought. I'm glad this came up. A friend of mine put his on the outside with the washers. He hasn't had any problems YET. Do you think he could?
At 5000 miles on stock clutch 05 ???
Jon,
I'm at 5000 miles on stock clutch, 05 F seems to be running/shifting ok.
I ride conservitive, When / at what milage might I expect to try and get on your
schedule for clutch service / other needed service.
You come highly reccommended - Can you PM me your contact into for service - Thanks
Ain't nothing but a thing ---- minimal 2up comfort mods
Mustang seating, National Cycle switchbld, Bub's, Aeromach 6" risers, sissybar/rack/mutazu bags
Kuryakyn drivers swept swingwing & passenger swept pegs
05 1800F spec 3 - a little less cool, a whole lot more comfort.............
It'll work either way

Ahh good deal.
I saw something about drilling, but no I did not do it.
Interesting point because:
All friction plates and all steel plates will rotate at the same speed (but if there is slipping, there wll be a speed difference between the steel/friction plates but as a whole group), for the steel plates to turn dark, it means that they were subject to more heat and that implies that while the clutch was slipping, those disks had greater grip, maybe due to less oil...
Interesting that those are the disks in the part of the basket that had no exposed notches/grooves. Time for the dremel maybe... let me go see the basket... BRB
I've seen them fail at less than 8k miles and seen them run for over 50K miles. It depends on the rider. My was slipping at 8K. PM Sent

If I were you I would swap out the stock springs for heavier ones at my next oil change. My stock clutch just started slipping at 9000 miles on my 07 F. Now that it started slipping I will be replacing EVERYTHING with MTC. If I had put in heavier springs when I put the pipes on I would probably have had no worries for many mile to come and only had to buy a set of springs.
I measured a new set of MTC and good steel plates, 1.763

When u talk about shims u talking stock springs. The new mtc clutch comes with better springs. Ever with the heavy duty new springs still shim. Cause the new kir says new and inproved or something to that effect.
