I asked Ulis about the

I asked Ulis about the crankshaft - it is not the conrod that is longer but the crankpin. The webs are fatter on some cranks and they require a longer crank pin.
Conrods still the same length.

video clip - what do these rattles mean???

R69s engine running

I have done a very poor video which captures the sound track of our R69s engine running.

Are these rattles piston slap, little end knock, big end knock or maybe all three.

Comments and advice would be appreciated.

Why do I see long conrod sets

Why do I see long conrod sets for late model R69s?

But I do not see different pistons ( one to suit long and one to suit normal conrod length??

Does anyone know the way of telling which motors have which conrods?

Thanks in advance

Kurt Thank you for your

Kurt

Thank you for your input. It can be a bit like pulling teeth to get all the info one needs to maintain various aspects of our bikes.

I want to get a crankshaft for my R69s, so when I pull it down I can shorten up the time taken to get it all back on the road.

Thanks again.

R69s crank - long conrod Vs shorter conrod

I see there is two versions of the R69s crankshaft - one with long conrods and the other with shorter conrods. However in my parts manual I see only one R69s crankshaft complete part number - 11 21 0016066 If I assumed then that there are two different sorts of pistons - with different locations for...

in my parts manual

I haven't ordered from Meyer,

I haven't ordered from Meyer, but I went on to their online store and found items I have been unable to get from Mark Huggett. Being in Australia, shopping locally in USA sort of doesn't count, so I reckon look everywhere because what you need is what you need and different places might have much of...
