a jump in revs from 5k to 6.5-7k

[Rob S.]

I looked at it, and at the 2:57-ish slip (you called it a 'jump'), I could not clearly see if any of your left fingers were touching the clutch lever. Can you see, or recall?

Did adjusting, or over adjusting the cable make any difference?

Next time, can you eliminate the music?

If this is a pushrod clutch adjustment is easy to mess up
It requires changes at both the perch and the pushrod end

It looks like your engagement point is too far in.
Bite should probably occur with lever closer to the bar.

The pushrod end is fiddley a small turn in on the screw is quite a significant change. Unlike th perch

There is a clear set of instructions in the 83-86 550 manual.

clutch was not pulled in at all at that mark, yeah sorry bout the music lol

im hoping i can just adjust the clutch and fix this, havent tried it at all.

When I saw the problem, you had backed off the throttle then nailed it again, next time when you just held it wide open it didn't seem to slip. Mine have never done like that, if you crank the throttle open at say 2500 rpm, & hold it there, when it gets to the point it's going to slip it will slip. I'm trying to imagine what the backing off then nailing it has to do with it...One thing is for sure "your clutch is slipping".

it doesnt seem to happen everytime thats why i was trying to get it to happen with things ive done in the past that would get it to act up, when i go to pass people and give it hard throttle it would do that, and also when i run through the gears like i did in the very beginning it usually would slip once i got into second.

im hoping an adjustment could help fix this issue as it doesnt seem to happen to frequent but it is enough to where i will back off of the bike a bit to make sure i dont cause it to slip.

could it be related to anything other than the clutch? its only happened twice, and those two times have been recent but when i went to downshift into first the bike would not go into first, eventually it did but it took a few attempts to do so, id hear the grinding when it wouldnt go, never had the bike pop out of gear or anything else odd but i figured id add this.

grinded when going into first again afterschool and when warmed up, still have to adjust clutch hoping it fixes the issue, noticed the slipping happened alot more this morning while it was about 45 degrees outside

Clutch slippage?

Cipher's observation would indicate that it is slipping because it is not adjusted properly.

And yes, when it’s cold out you will see it shift a little harder at first. I will usually get the revs up a little higher before shifting to help it. Once the oil has warmed up, your shifts will be easier.

But i also can’t believe I’m saying mid-40s is all that cold too

Its appalling that th OP would not make an effort to do such a simple thing.
Driving it in this state is dangerous to himself and others
It is damaging the clutch and plates even further.

Ten minute job max

But the obtuse are obtuse for a reason.

 

[timebombprod]

I knew that it needed to be adjusted...I never said I wasn't going to do it because it obviously needs to be done, I just gave an update as to what was going on yesterday morning, it's been slipping for a while so it probably needs work either way.

I adjusted the clutch from the bar end today and I am able to get an earlier engagement point but my wheel tends to spin on the service stand when the clutch is fully pulled in, and another thing... I'll just post the video.

clutch is now fixed and i learned that the only reason anything manual stalls is because the weight on the moving wheels, glad i fixed it thanks again.

 

[rphillips]

Congrats on getting it sorted out, well done.

thanks lol, it was going on for a while so i didnt see it as a must finish now thing, i did adjust it the wrong way the first time and it would slip every single time i gave it more throttle than riding like im in my neighberhood, when i got it back to where it was it would still slip basically just as frequent but it wasnt at the right adjustment there in the first place, finally got it fixed once i got home after school and it has slipped a tiny bit twice going real hard on the throttle so i just gave it a tiny bit more adjustment and now it should be perfect, i believe it was a bit cold when it did slip those two times since then but still i had room to play with.

the good part is i only had to adjust from the bar side

also learned clutch-less shifting right after, very fun; aslong as its being done right it doesnt hurt anything. wondering how much my 0-60 will improve from this. i also finally hit the speedo limit (and a little more) and now my speedo bounces all over the place sometimes, went ahead and took the cable off from the gauge side, lubricated it and put it back in ensuring it sat correctly, checked the cables for bindings and it was good and i also routed it a little different to give it the least friction it could get. havent rode since then but hopefully it helped, if not well i guess thats what the forum is for.

Clutch-less shifting can be fun. When you're in a company truck and your passenger didn't know such a thing was possible. Or you're riding an old motorcycle and you're carrying something with your left hand.

But save it for when your linkage breaks and you've got to get home. You've already been having clutch troubles for quite some time now, why ask for trouble?

it doesnt damage anything aslong as you do the shift correctly right? i just plan on doing it for going fast although it seems to be easier than normal upshifting as you already do blip the throttle, its just one less step. ill get over the fun of it soon and just use it for going fast lol.

You've heard about 'quick shifters' (which are on all modern superbikes)? They kill the ignition momentarily for full throttle shifts.

As I recall, smooth, clutch-less shifts, whether on a bike, car or truck, occurred only if you hit the sweet spot: a little throttle, a little pressure on the shifter, and when you hit that spot, the shifter just moves, and the gears change. NOT at full throttle, not for racing.

You don't have a quick shifter on your bike. Neither do you have the older version, an 'air' shifter. Stop pretending that you do.

Ian, If you're "blipping" the throttle on up-shifts, you're doing it wrong, whether you're using the clutch or not. On up-shifts, you need to roll off the throttle, to un-load the transmission, to allow a smooth gear change. The guy in the video says as much. Doing this shouldn't hurt anything, but why chance it. Your 650 shaftie is no drag-bike speed demon, stop pretending that it wants to be.

On down-shifting, where rev matching is important to allow the smooth gear change downward, "blipping" the throttle is prescribed. However, doing this without the clutch disengaged, results in increased speed, when the whole reason you were downshifting in the first place was to decrease your speed. If your reason for dropping down a gear is to get more torque/acceleration with the intent to pass a vehicle in front of you more quickly, then maybe a clutchless downshift could shave a 1/10th of second off your downshift time. Not worth the trouble, in my opinion.

The guy in the video, I'm sure, is not recommending doing this on a 40 year-old bike, with sketchy past, that still doesn't run quite right.

All just my opinions, Ian. I really do appreciate your efforts to improve this bike, your understanding of it, and your riding skills.

I might be using the word blip wrong, I mean what he says in the video, when I think blip I just think of a quick motion of letting off the throttle and going right back on once the shift is done.

Don't worry I'm riding pretty normal on it right now, the clutch less shifting is just for fun but I should just focus on riding right now lol.

I figured he's not talking about old bikes but these bikes are pretty modern in my opinion as far as the characteristics go, other than being efi and having a million sensors they got everything going for them.

I am gonna need to get a faster bike at some point but I really want to hang onto this one and at some point bore it out and throw an intake on just to get some more power going, I have a bunch of fun on it.

Then yes, you are using the term incorrectly:

[FONT=&quot][FONT=&quot]Blip the throttle[/FONT]


[/FONT]
[FONT=&quot]
Blip the throttle means that after the clutch lever is pulled in, the throttle is quickly opened without slowing the engine RPMs after lowering the gear and releasing the clutch back. In other words, throttle blipping is clutch in, blip the throttle, lower the gear and clutch out to match (approx.)

And, to me, your desire to "...at some point bore it out and throw an intake on just to get some more power going" would be a waste of time and money. But, to each, their own. I have no doubt you are having fun. Keep on keepin' on.
