Like a dumbass, i forgot to tighten one of my spring caps, and the thing blew off while the bike was running and took the post with it.
Just want to make sure, its a $150 part, just need to replace the whole hub unit right?
Remove the plates, unlock that bolt, and swap.?
Yup gotta replace the hub. pull the plates out carefully and stack them in order. Use an impact gun on that nut for removal if you have access to one. They can be a bit stubborn. You can run with only four springs (I too have broken a post off in the past) clutch never slipped on me for the hundreds of miles I ran it with 4 springs but YMMV. (I broke one post off and took the spring opposite to it off for "balance")
Wo, what? You just forgot to tighten 1 and that happened? I've heard of people running with only 4 and having absolutely no problems... Or were you already running with 4?
I run all six, i just had 1 that i didnt completely tighten down, and over the course of 400miles today, the bolt slipped and i lost the cap, spring, bolt, and post somewhere on the brooklyn bridge, litterally 10 mins from home. I was lucky that i was only idling at the time and i noticed something hit my ankle pretty hard. Had i been on the highway on the way home, it might of jammed and the engine might have sieized and without anyway to disengage and would result in probably me crashing. :P got away with this one.
I push the bike to the side and made sure the other 5 were good to go, and they were fine. ill post up pics tomorrow of the carnage, just wanted to sleep easy on the fact that its a simple replace and a lesson learned. ( i had torn my bike apart and that was the only thing that i forgot. [bang] atleast it wasnt something that might of caused more damage.
Sorry about your hub, but glad to hear that you're OK.
thanks!

You're looking to sell your 5-spoke Speedymoto clutch cover?
nah, its the kukri gold plate. Apparently speedymoto pressure plates wont work with the desmotimes light weight piece.
however, when the posts snapped it took a piece of the clutch plate with it, it looks like it was dropped on the concrete.
droolling over this thing. Titanium posts that are replaceable.

When I saw your post, I immediatly thought of the moto piece. Sure it's $60 more than the desmo unit....the desmo unit is a complete failure though being the first time you drop it the chunk is junk.
i concur, ill run it with 4 springs until paypal sends me one of those 10% off coupons and drop the cashmonies on this baby. that 1lb of rotating mass there will probably free up some hp, i wonder if it will be noticeable.
Damn....when the hell does PP send 10% off coupons!
every now and then theyll send me a 10% (up to $100 off) coupon. and it sucks cause 1/2 the time i have nothing i want to buy. :( the code they give you is only good for your email account though..
I have a faded red Kukri pressure plate.

Can anyone guess why the reflection on some points of the Powder Coated Clutch cover is red? [evil]
You're bleeding?
i am completely confused by most of this thread.
isn't that how most of my threads are? ;D
Let me give you the rundown
1) Clutch post snaps from stupid mistake
2) I just saved a bunch of money from switching to progressive (actually only $12 bucks)
3) Pictures of my clutch posts being snapped off
Oh and the red is ducati 749s in my garage. [evil] unfortunely not mine :( and also with a bent posts on its slipper clutch.
4) confusion continues
dam I was gonna say red 999. I was close
i'm just really surprised the post snapped off!
Order from VeeTwo directly, and you'll save a ton of money. Just a headsup.

i checked their website and tried to request a quote their servers all fubar and giving me error messeages so i just sent a direct email.
also 1USD = 1.384AUD so yea i should be saving a significant bunch if shipping and tax wont offset it.
I thought about how common it is to break a posts....and this is just a freak accident, and if i go down, i doubt id snap a post since i have the thicker pressure plate + clutch cover. and yea, im suprised it just snapped off. it would be one thing if it bent. i guess thats what happens when the bike is on lol
I'd run with 4 springs and watch Ebay for a replacement hub although (as pointed out above) many people like and leave it with only 4 springs. Whenever your clutch is apart, shuffle the pack and deglaze the drive plates.
I think it is more likely that you over torqued one of the bolts and cracked the post. Then while it was running the post broke off losing the spring, reatiner, and bolt. If the bolt fell out first, there is no way the post would get broken off.
+1. There'd be no stress nor any contact to the post. Its skinny enough that it won't contact the holes of the pressure plate really, even under "play" of a worn basket.
And the 4-spring clutch works great on my 900, never slipped, and i've got thousands of mile on it, rain and shine.
I've seen the aftermath on two bikes when a bolt come loose.
They slowly back out until the spring retainer catches on the cover, then it snaps the post off.
I don't think you could put enough torque on the 5mm bolt to snap the post.
Lots of folks have tried, and all that happened is they snapped the head off of the bolt.
oh. the cover. there's the missing piece that makes it make sense.

Makes sense. I was thinking no cover since the parts fell out.

ahhhhhhhh. i can finally visualize it now; it's all making sense. i'm stupid. thanks Speeddog.
speeddog has it correct. if i was running with out a clutch cover then it would of just popped offm but it got caught and took the post with it.
i usually just finger tight all of them then tap each one with two fingers to make sure its snug, but i guess i missed one, :(
funny thing happened, as my friend was driving back from school, i stopped by the site where my clutch post snapped and pull over. i spend about 5 minutes looking for my part....
it was laying on the sidewalk, it looks like it was untouched by cars too (well, the damage looks lke it was caused when it snapped off) how cool is that? or how sad is it to see that nyc is really teh dirtiest city in the country.

emailed the guy, i need to know if its the same one desmo times is selling for $275!!! and this is with a basket! not sure if the basket is steel or aluminum, if its aluminum, its practically worthless to me as id wear it in out in no time.
edit:
Hub = 515 grams
Basket = 440 grams
paging taft. taft, paging taft. is this light weight enough? lol
If you found the post, weld it back on. If not, please send to me, I weld 'em on and give them to some of the local kids (and myself).
Will let you know as when the new one comes in (in a few months, since my huge stack of singles is going towards a new compressor). the only issue is, your going to have to rethread it. but im sure thats not a big issue for you
I find it funny that the one you didn't tighten was the marked one to tell you where to line up your pressure plate. I always start with that one. The little line compels me to. [cheeky]
