Shift Return Spring Failure Poll

[Greg Field]

I know where they are: Kentucky. What special prize do I win?

$100.00 ! Wow! You are good.

Are you on the show "Psychic Shift Spring Locater" ?

 

 

 

 

p.s. I'm glad there's still some humor after a winter of oil temp. sensor and recesion responsibility arguements.

I'm in the "if it aint broke dont touch it" camp! lol all these shift spring stories are enough to make a guy paranoid. Its still better than having a new 8valve Griso with a bum engine.

It's only really special guys that have both! boo hoo

oh yeah, and the single plate Scura clutch too.

 

Expect to hear more from me in the future.

Hey, why not having a proofen Guru bend one for you or better this forum? To get the most out of it he must make limited runs of them. 150 for the first lot. Then, a year later another and final 100 of these then already legendary bullet and nuclear bomb proof "XY-springs".

The idea behind that is that some buy a bunch of them, others buy none, and of course all the newcomers can only read of them in the archives. So you very quickly come up with a 2 classes forum society: those who are multiple equiped and those beging and crying for getting one of them.

 

Try it, it's fun! At least for the third group

Mine's never broken and now has 25,000 miles. I've been thinking I should change it out pre-emptively.

40,000 miles on mine

CRAP and double crap. When you say updated spring, you mean the one with a wider circumference coil? So the bigger coil broke, even on a 15mm boss?

CRAP and double crap.

 

I just installed the "updated" Guzzi spring last night. I assume that's the one with the larger diameter coil? The spring that broke in my driveway yesterday was a Cannon Racecraft spring that I installed 7k miles ago. When I installed it ground down the boss on the pawl to 15mm.

 

Here's the broken Racecraft spring next to the new Guzzi spring:

 

Here's the pawl boss that I ground down to 15mm from 16mm (.590" = 15mm):

 

The good news is I had a great ride today and the shifting was better than ever with the Motobits kit I installed over the winter.

It seems that the "updated" spring broke on me yesterday  .  I haven't pulled it apart to verify that it's the pawl spring but the symptoms are the same as the last two times that I went through this.  I got almost 20k miles out of this one.

 

From now on I'm just going to change this spring about every 10k miles so I don't get stranded.  Since I keep my bike in my basement during the winter It'll give me something to do on some winter night  .

2002 lemans 35,000 and still working fine.  I put Red Line oil in the gearbox early on

Someone on this site installed a pull-type spring to hold the pawl up against the shift drum. It looks like "the fix". If mine fails , I am going that route.

First time I see this poll!
However I miss the option "Never" (That's 35.000 kms +)

[Tom M]

Maybe I shift too much?

 

Sculler2x, I've been using Redline shockproof heavy in the gearbox since I bought the bike.  It won't help the pawl spring.

 

Gene, I might look into that secondary or alternate spring.

 

Great sig line there Jaap!

65.000 km+ on the original spring from factory on my '99 V11 Sport.
