I recently picked up this 1994 Funduro- I really like it! it's really fun to ride and the thump from the single cyclinder is really addictive.


Tire Fuel tank Wheel Sky Vehicle

I have a couple of issues: the clutch is slipping at the moment, it's at its worse when accelerating hard up through the gearbox. After a little while of motorway cruising without using the clutch it seems a bit better and doesn't slip when, for example, accelerating hard in 4th. Since it's worse after lots of shifting, it makes me think that it's maybe when the plates separate and get covered in oil that it's worse. That makes me wonder if an oil change would help? Wishful thinking perhaps.

If it does come to needing a new clutch, I notice that a lot of the kits have uprated springs which I'm not too keen on. Can anyone recommend a decent and cheap kit?

Finally, I have read about the front sprocket and the design of the circlip, hence I have ordered a new circlip with my oil change bits from Motorworks. How does this sprocket seem? Too much wear on the splines to be comfortable?

I would change the oil, a previous owner may have put in friction modified oil. That is not designed for wet clutches.
The wear on the countershaft can really only be seen when the sprocket is taken off. There is supposed to be an O ring on the inside of the sprocket, it may be missing on your bike. It goes in a groove on the countershaft.
I have a short article here on what I did to my bike to get rid of the circlip problem.
My friend who I bought the bike off had the front sprocket fall off one time. When I got the bike the circlip would regularly bend as the sprocket moved in and out. So I drilled , tapped and fitted a stud into the countershaft to allow a nut to hold the sprocket on.
BMW became aware that the circlip was a dud idea and changed to a threaded countershaft and nut in 1997.
Good luck
Pete

I assume you've already checked for proper free play in clutch cable.! Someone may have put a full synthetic oil in there causing an issue with your clutch. A couple oil changes with regular dino oil might solve it.

For a '94, that bike really looks like new, man.
I recently acquired a 97 and just like yourself, I instantly fell in love with it. That "old thumper" that kicks a** when you twist that hrottle,
the looks, the seating position... it's just an amazing bike. After riding bikes for 30 odd years and having had many different types of machines, I was like "where have you been all these years ?"
It's a great motor and it just lets you know when it is time to shift up , and more importantly when to shift down as it begins to protest when you "gas it" :)

Enjoy that beauty, and take good care of it. As a co-worker of mine once said : "white is a fast colour" :) And it looks really good in white.

Try doing a few subsequent oil changes about 100-150 miles apart with the proper oil and I hope that helps sort out the problem.

Good luck and RIDE SAFELY

Hi and my first post on this forum as I am thinking of buying a 1995 Funduro. Did you document or video the procedure for curing the circlip problem by drilling and tapping to add a nut?

Apart from the circlip and head bearings they seem virtually un breakable.

Cheers

EDIT: I see now after reading again that I should find it on here, thanks
