Paralever Driveshaft

Has anyone had experience with these?

http://www.ebay.com/itm/BMW-Motorcyc...item20c01f8d8c

And if so ... what's the good /bad, etc? I have a new driveshaft in my 91, but it will eventually fail, and just doing a bit o' research.

As always, Thanks in Advance ...

There is a facebook group about his Airhead Club in Australia ... and anyway the guy is a hoot (good thing!). He doesn't have a lot of literature about it, but he claims that they last about 200 Km, and then you 'wack' in a new set of CV joints and new rubber kush cartridges, and you're good for another 200 Km. At half the cost of a new shaft (installed) ... it might be the way to go.

Facebook Club: http://www.facebook.com/#!/groups/Ai...0563518021073/

I have no idea about shipping ... and I have no idea if it's real ... but it seems like a great thing if it is ...

There's a whole other thread on this unit from last summer - suggest you go there and start reading.

The BeemerShop is supposed to have exclusive rights to distribution of these 'shafts in the US. Looks like Ted is charging a fair price for them.

I've also got one in right now. Seems to be holding up fair well.

I think we have seen one shredded here on ADVR but that doesn't mean they all do that.

That wasn't one of these. That was one of the HPM rebuilt units. From what I remember, the suspected cause of the failure was contamination of the cush drive by the leaks from the final drive. This failure was very rare - he puts out a good product.

Yeah, mine's out of phase right now (check out the angle of the u-joint at the front that bolts to the tranny on the right).

Smoother, eh? That'd be a plus in addition to some peace-of-mind as this shaft is going on 60K (the one on the left crapped out at ~30K).

They can be found in Europe also !
The thing is to know if they last , at least longer than the original ! Mine was gone at 30000 km. The second one is still good , so far....
How many miles on your aftermarket ?

Thanks, I thought they were one and the same. Are they designed different? Since the final drive input seals leak on a very regular basis, I hope they are fairly oil resistant.

So what am I supposd to see here?Is the four bolt flange on the end supposed to line up with the universal.

If Stagehand gives the aftermarket driveshft the thumbs up given the way he beats the living daylights out of his GSPD then it should be fine for bikes ridden by the average rider.

The original driveshaft on my GS looked much like the one on the right but worse. My whole swingarm was filled with Hypoid when I got it and the rubber was swollen and oozing out of the shaft. The shaft was also about a 1/4 turn out of phase. I'm running an HPM now which is filled with a firmer (polyurethane) material that is similar to skateboard wheels. My output shaft and FD have all been resealed, but I hope it is more oil resistant regardless.
