Downshifting Issues

Postby portugeezer » Fri Feb 17, 2012 9:06 pm



At the end of last season I started to notice that my bike would sort of stick in each gear if I downshifted at any speed but the speed you would upshift at. Are my syncros going out? If I say shift from 1st to 2nd at a certain speed each time I can only shift from 2nd to 1st at about the same speed or it doesn't click and I wind up started out in 2nd gear because it wo'nt go into 1st if I didn't downshift until I stopped. I tried some MMO in the oil but it did nothing. Took a long ride today and it seems to have gotten worse since last season. Any ideas? Thanks in advance for any advice!

Sounds like a clutch issue, have you tried to adjust it and have you checked your oil level recently? You can try moving the adjuster at the lever in or out to see if it helps. There should be about 5/8" of play if I remember right. If that doesn't do anything and your oil is okay, remove the clutch cover and adjust the play there. There should be a how to here on the site to explain how to do this or check your owner's manual for instructions. It also could be worn clutch discs or a broken spring.

I replaced my clutch cable because it had a few broken strands near the lever. It has always been hard to pull in I don't think a person with weak hands could even do it. It fully grabs when the lever is almost all the way out so i know it's pulling it to where it's definately not in gear. Is it possible to be pulling in too far? When I had the cover off to replace it I could move the slack in the cable a little each way with my finger. It rarely goes into neutral unless you shut the engine off either which is annoying at long lights. I have tried adjusting that cable every which way and it's still the same

Well neutral is something different altogether. For me, finding neutral when coasting is easy, but idling and stopped very difficult. So nothing unusual there.

Downshifting sounds strange. Do you use the clutch to up-shift? Sounds like all is well there so I do not suspect the clutch is the issue.

When you have an issue downshifting, can you at that same time up-shift? An if yes, can you then downshift?

Seems like a loading issue to me, particularly since you mentioned the lower speed needed to downshift.

The bike upshifts as smooth as glass always and I always use the clutch. If I'm doing 55mph and approaching a stop I have to pull in the clutch and slow down to about 45mph to get 4th then about 30mph to get 3rd then about 20mph to hit 2nd if I don't for even one shift the bike sticks in the gear I should have downshifted to. Like say I skip 3rd it will not hit 2nd or first no matter how many times I pull the clutch lever in or try to click the shift lever. So I have gotten used to downshifting at certain speeds and the bike works fine like that. I wish it could be fixed but I think it's really messed up

Strange and I cannot say I have an idea on what is going on. If I am at 55, I pull the clutch in and cost down to 10, then downshift in rapid succession to first, then up to neutral while still rolling if desired. So very different than what you can do on the same model bike. Hope others can help here.

I have ridden every other bike I have ever owned the same way you do Fred. This is an odd problem indeed!

I finally got the problem sorted out. It did turn out to be the clutch adjustment! I set it so it grabs fully when the lever is fully released. I left almost no additional lever movement and everything works even neutral! As I've said it takes some left hand strength most people don't have to pull that lever in! I play bass so my left hand is strong. I read that the springs that come with a new clutch are like that. It is even recommended that you mix the new and old clutch springs when you do this job! I suspect my clutch was replaced by the original owner and they used all new springs. It's a big job so once it's done you're stuck with it. A good friend of mine asked if she could ride the bike. She has been riding for decades. I said if you think you can go ahead. She said she can ride any bike. I said be my guest. She got on tried the clutch and handed me back the key! If I ever remove the engine I'm going to put in some reasonable springs but for now the bike runs great!

Glad you found success. Certainly you may have stiff springs, but. How smooth pulling is your clutch cable when disconnected from the lifter plate? Maybe that contributes more than you think. They are not bad to change out if fraying or if the housing is wearing away.

Also check that the clutch cable is routed properly. Mine had quite a sharp angle at the headstock before i re-routed it and now the clutch is a lot easier to use.

Hi everyone. I had the same problem with my gl1000 1976, four month ago. Thinking how solve it, I began to ride starting in the second gear. Unfortunately today morning the rest four gears jump failed also.
I Think I will to send repair my "cow". Do you know any official manual or some self user how has fixed this problem. Any forum or concrete information about it?.

two week later

Unfortunately after remove the from transmission cover, I could see all the parts of front gear selector and its run well. I have taken my time to change the screws, for allen screws, the joins and others.
The gear still not working and I do not dare to open the block motor, ... So my mechanic will be happy next month,...
