clutch, stalling

Post by wyly »

On the first ride of the day regardless how long I warm up the engine when I shift into 1st the bike lurches forward and stalls even with the clutch fully pulled in. With the clutch still pulled in I can start it immediately and then it's good to go and for the rest of the day and the problem doesn't repeat. :?

It seems to be a simple problem is there a simple solution. Am I not warming the engine enough?

Sounds like the plates might be sticking.
Even though it is "first ride of the day" had the bike been sitting for a couple weeks.?

first ride since December actually, but it did the same last September when I was riding everyday.

How much free play do you have at the lever, what oil do you use and where is the idle speed set?

Imagine you have a flat part, put a drop of oil on it, and place another flat part on it. Now press the two together, and try to pull them apart. Same thing is happening with your clutch. Before starting, put the bike in gear, pull in the clutch and roll the bike back and forth a bit. Doesn't take much to un-stick the plates.

Either garage is too small or we have too many bikes. Or Momma's car needs to go outside.

Yes, clutch plates maybe sticking and also could be clutch adjustment, on the center nut and cable as well

Another 'kind' way to sort this out is to put the bike on the main stand, start it up and put it in gear. Pull the clutch in and the rear wheel will still be spinning. Then gently and progressively stand on the rear brake while having some throttle on. It will then break loose with no shock into the transmission.

I always start the x in the garage and roll it out into the drive, about 20-25ft.

checked cable right where it should be, I'll have a look at the center nut next.

I'll try that tomorrow.

I would adjust it at that center nut anyway. If that doesn't work, try by giving your cable more slack.
If none of that maybe it is really stuck. I've heard of that happening but after sitting for very long time. My bike sat this winter almost two months without start and clutch plates did not get stuck.

Many of these clutches stick after sitting a while, but usually not just overnight. Adjust per the manual, as has been mentioned. I replaced my '79's clutch a few years ago with 100% stock Honda components and it sticks after sitting (a year or so!) also. No big deal really, just make sure your bike is pointed the right way if it doesn't break loose and you miss the brake for some reason.

CLUNK, lurch, stall, (sigh) re-start, good to go.

My 80 did this. Now while the bike is warming up I pull in on the clutch lever and release it a couple of times prior to putting it in gear. It seems to help. No more stalling. I do this while applying the front brake though, just in case!
