Hi,

Has anyone had any experiences with the NEB or ABSAF crank, just as a replacement for the original standard crank?

I was looking at building a 2nd engine into original GS cases / barrel I have acquired. smile

Many thanks

Mike.


Mike.

Swan used a Pearson crank in his Goldie build.

My crank came from Steve Tonkin, many years ago, though remained unused until 2 years ago. I suspect, but could be wrong, that my crank was actually an NEB. It it a very nice piece of work, with a modern rod and big-end.

It is balanced per original spec's and vibration is certainly no worse than I would expect. As for reliability: hard to tell, as it's done only 900 miles.

I also bought an NEB belt drive kit from Steve around the same time, which is also still unused (I went with a Phil Pearson clutch and chain setup in the end). I have spoke to both Steve T and Bob Newby about the belt drive and both have been most helpful. It is a quality bit of kit too, and even came with a clutch holding tool.

Mike: I bought an ABSAF crank for my ZB34GS as per the photo below but have yet to use it. It seems to be very nicely made. I gave him the weight of my piston for balancing purposes.

A local pal bought a complete standard GS engine from ABSAF and he is very pleased with it after about 3000 miles.

Although I have not bought a crank from Phil Pearson, the bits I have purchased from him are just beautiful.

From a recent enquiry I know for certain that ABSAF will ship an engine in about 5 weeks from ordering. I would think a crank would be much quicker.

That looks very much like my (presumably) NEB crank, though mine doesn't have the flats adjacent to the big end.

Phil P's cranks are works of art. He wasn't doing them when I bought mine, or that would have been my preference. He reckons the oval versions (which he also makes) are the best, but I don't think he likes making them! All his cranks are numbered, like limited edition artworks!

Ran a NEB crank in mine for several years, rev it to 8K, no problems at all.

With big rev in mine I'm more worried about how the cases handle it! And they're NOS!

I am waiting for my Pearson crank I ordered in December his work is in high demand so I figure must be good. He told me was doing a batch in April I don't know if they are all spoken for.
