I always pull in the clutch during every stop when I downshift... panic stop or the normal kind...

I'm confused. In the original post you said you would have bent your crankshaft had it not been welded due to a panic stop. Is there something I'm missing?

The thing that really gets to me is during that one( ok maybe 2-3 times) a year that I HAPPEN to move the shift lever the wrong way, I end up spilling my beer all over the tank!!!!! question is, will welding the crank help this?

I think more about my primary during an accidental downshift than my crankshaft. That poor tensioner must be a lot tougher than it looks, to be able to take such stress when you let out the clutch in a lower gear like that. The crankshaft seems so robust compared to the primary tensioner.

The more I read about "twinkies" the more I'm convinced to keep my 27 year old Shovelhead FXR

Scurvy..I killed my last 2 crankshafts with hard downshifting...Not braking...

What are the initial symptoms of a bent or crank? Can you tell w/o havng to go in there an check the runout?

I am curios why you are down shifting so hard, are you down shifting 2 or 3 gears at a time?

tireater · January 23, 2009, 07:08:41 AM

On the St Bob...I was pulling 3 Ducati's up 154 when I passed a cop going the other way...I was doing over 90 in a 55...
So I sped up and found a nice private drive way to hide in a couple miles later...Stopping from 100 killed the C.S. ... downshifting...
I always ride fast and can't imagine not downshifting unless I am putting between red lights....

Jeffd · January 23, 2009, 09:52:15 AM

Not to be critical but try using your clutch and front brake. Front brake will slow you down way faster than dropping down a couple of gears and dumping the clutch.

tireater · January 23, 2009, 10:05:12 AM

I don't drop it a couple gears and pop the clutch...I down shift and use motor braking on the back wheel...
On my last panic stop I locked up the front wheel a couple times while motorbraking...
I ride a supermoto too fast...One finger on the front brake and motorbrake with the back wheel...
You keep the rpm's up and almost use no brakes...esp. no rear brake...
We mostly ride twistys fast around here...I can't imagine doing that w/o constant up and down shifting...
Just braking while pulling in the clutch will let the motor fall out of the powerband ...
This puts you in a bad position to power out of a situation...or a turn...

I was going to ask the same question that Jeffd asked but he got there first. Your explanation is very clear and I find myself occasionally ridding in a similar fashion but a little less on the edge than it sounds like you ride but with all due respect......maybe you should consider another brand/style of bike for that kind of riding. HDs just aren't made to be riddin like a supermoto without expectations of gernading once in a while.

tireater · January 23, 2009, 10:49:16 AM

I ride them, break them, fix them...repeat...You don't hear me complaining...It's a hobby...not just a couple bikes...

tireater · January 23, 2009, 10:56:08 AM

I have been told I should switch my motors to wing nuts...as often as I have them apart....

blk-betty · January 23, 2009, 11:49:53 AM

Well Ok then, sounds like you have a good grasp of the situation.

Have fun, sure sounds like your style of riding is fun. Lol, if I lived closer to the twisties I'd probalby be doing something similar myself.

I suggest Dzus fasteners.If you waste another crank you may want to change your username to "crankeater".
BTW,I enjoy reading your posts!
