Too Much "Slop" between Accel and Decel

[Bigincher]

From my vantage point, the compensator parts look to be in real good shape. It's a simple design that's been around since the mid-'50s, and I've never seen anything like them 'jumping the cogs'. Worst thing that happens is they get gummed up from non-lubrication, or the spring breaks. No, I think that's barking up the wrong tree....

Hi Ken

The Cams are always in contact with each other..
I'm not sure what I said for it to sound diff..

Yeah, I suppose that's why they're there,, to dampen..
Like I said, I do not feel any diff when I run the 127". with a C-S or the others without C-S's..

I'm still racking my brain over this ratcheting sound at Full-Boogie..
I do not believe it's anything "jumping" anything..
If there really is any extra slop, or is he just noticing what's alway been there,, and/or does it have anything to do with this ratchet sound..

Developed into a kinda fun and interesting thread huh, at Unc's exspense..

To my way of thinking, if this mysterious 'ratcheting sound' is directly related to the drive train, you'd feel it as much as hear it.....

I keep going back to the primary chain......

Frisco, Ken and Big

Thanks for your time in this....

The compensator is probly ok and definately not jumping........ rear belt is probly not jumping either ...

I really hope it is not inside the tranny, it didnt have much metal on the magnet, and all the gears looked real good.

That leaves the clutch... I took it out and put it back as a unit and didnt look into it.

Soooo.... I will take it back out, (the clutch basket) and look into it for signs of something.

The chattering/rathcet sound is only at full on throttle, and as you all know, hanging on, watching the road etc AND listnening for where that is coming from is real fun. It may well be the clutch. I thought it was there before I scattered the original clutch, and then again after the indy shop replaced it under warentee.
I paid $50 more for them to upgrade to kevlar on the new clutch pack. They said there was no nuthin' left on the plates when they took it apart... all the friction ,material had exploded and ended up splattered on the inside of the primary cover... all the guys at the shop wanted to know what the heck I was doing when it let go. All I could say was..... "about 135"
Some puke in a bmw thought he wanted a race.....I spanked him hard until the clutch let go...then I had to hang my head... let him go on by, after he caught back up...........I coasted for almost a mile or more to the next exit on the freeway... and rolled all the way to a coffee shop, into a parking place... didnt even hafta push it.

anyway;
If I just go ahead and buy a new clutch, what would you all recomend? Now ya know my riding syle.
I will get out my parts book and look at them tonight.

Oh yeah! I feel it all thru the entire bike... handle bars.. seat... foot pegs...
a little more on the left than the right...

I wish I had thought of it... Big, you could have taken it for a blast over in Dixon! then you would have first hand knowledge.... but that day I was in the cruise mode and not riding that hard.

Not every day you would hear... Hay! wanna ride my bike and beat the crap out of it???

I appreciate any and all help here... I was measuring the ''lift'' of the comp sprocket... I probly shoulda said that when I posted the fuzzy pictures.... so that's a ''oops sorry'' on my part .....
I dont have a new comp-sprocket to compare, but after looking at this one and pictures in the book... it is like Frisco says... pertty dern good shape...

Could it be the clutch shuddering?
I have never had a bike clutch shudder... like my old chevy back in high school... start to let out the clutch and have the foot pedal start jumping and the truck dancing the same jig, till ya give it enuff gass to git er moving.

This bike is smooth as silk at take off, but I suppose at full-on throttle it could be shuddering? (anuther word to desribe the ''sound'')
Like the dragsters at half track start to shudder and they gotta back out of it?? only I just keep on it till it's time to shift.

Hi Unc

I cannot say if it's the clutch shuddering/chattering/ratcheting..
I only brought up the clutch because you changed the word to "chattering" and that's kinda a clutch prob sound/feeling and very much as you described with the old truck..
I had a chattering/shuddering clutch many years ago, it was nothing like your ratcheting noise though..
It only manifest itself at take-off.. A wee tweaking cured it..
You're throwing us curves here Unc.. Is it Ratcheting or Chattering or Shuddering or maybe shaking, bumping or banging..???

If it was me, I definately wouldn't just go out and buy a new clutch,, heck,, you don't even know what the prob is yet,,, calm down..

NOW----
I want to correct something I said..
A couple nights ago I assembled my early 80's C-S, which is much like yours, onto a motor-shaft and was holding it in my hands..
I was rotating the motor-shaft and C-S in my right hand while holding the spring pack in my left..
I observed how the sliding cam would get to a certain point on the splines and would start to spin while sitting in the spring pack which is just like your spring pack..
I was shocked that I was Not aware of this movement cuz I am pretty familiar with these things, How could I not know about this.?
I then posted about this "spinning" a few posts back..

OK, has anybody guessed my mistake.?
I'll wait and let our detectives catch my flaw..
I've revealed everything you need to know..
