At times, my Wolverine has a hard time upshifting to the next gear. This issue usually happens when going from 1st to 2nd or 2nd to third. Once the machine has been ridden a bit(a few hundred feet) and warmed up, the problem goes away. I have a feeling once the gearbox and oil warm up, things work properly.

Will adjusting the clutch freeplay hellp this issue at all?

 

Mine does the same thing (2004). I don't think it is anything to worry about. I have tried to adjust the clutch free play and it didn't help. Once you ride it a few hundred feet it is fine. I am more concerned about the rattles in the engine when it is warm but have been told it is normal for an air cooled Yamaha engine. Adjusting the valve clearance doesn't help. The dealer told me that sometimes the clutch will rattle. Haven't found the source yet.

 

Ok, cool. I won't bother messing with the clutch. What weight oil are you running? I'm running 10w-40.

I like those mudflaps you installed on your machine. That looks like a pretty straight forward project.

 

Thanks. I've got to replace the right hand mud flap as I put a large stick through it a couple of weekends ago!

I'm running 10w-40 Amsoil (full synthetic).

Took the Wolvey out for a short ride tonight. Shifted fine from 1st to 2nd, then didn't want to shift into third! After running for a short while the shifting smothed out. Just a quirk.

 

What did you use for the flaps? A regular automotive flap cut down?

Same issue I had the other day! Went into second, but had trouble going into third. Do you notice the issue gets worse in the winter or stays about the same?

 

I'm interested in those mud flaps also, other than some carb issues that is that is the only problem I've had with my wolverine, getting so much mud on my boots that I can barely lift them off the footpegs....

 

If I remember correctly I used truck flaps purchased from Advanced Auto. They do keep alot of mud off your boots.
I was po'ed that Yamaha stopped selling the overfenders for the Wolverine. I know that Moose makes a some but they need to be trimmed down some. The Yamaha flaps looked just right.

The shifting issue does seem to get worse in colder temps.

Also, go ahead and check the free play on the clutch. I set mine when it was fairly new and am planning on doing it again now that I have some hours on it (70).

 

Thanks. I'll look into the freeplay. Seems like a pretty easy adjustment.

 

Sorry to bump an old thread guys....

I went riding Friday. High temp was about 45F. In the morning, it was probably in the upper 30's/low 40's. I'm running Castrol motorcycle oil, 10w-40...NON synthetic. I just changed the oil last week, this was my first ride with a fresh oil change and new filter.

Shifting was OK, but I had a heck of a time getting the machine to shift out of reverse in the morning; even after it was warmed up. I had a back up a few times, but it would not shift out of reverse when I wanted it to. Usually, backing up another few feet solved the problem. In the afternoon, I had no problems at all. Shifting out of reverse happened as it was supposed to.

I'm going to adjust the free play tomorrow. I'm open to any suggestions though.

 

One thing it could be is if you are using the wrong weight oil for winter weather. The oil is so thick that the clutch is dragging/sticking. That would explain why the problem goes away after the motor heats the oil. Just an idea.



-- I forgot to keep reading.. I just noticed that you already tried oil.
