Reelrazor I was wondering why you did not use thin jamnuts against the large nut welded on these dogbones ?

You wouldn't need to. Since the dogbones only unscrew from one direction there is no way for them to turn while they are on the bike.

Correct.

The individual pieces are 'trapped' by the pivot bolts thru each end.

I was thinking more about the play in the threads working and wearing from the lateral loading and unloading of the suspension.

Why do you lower your bikes? Is it to make up for an aftermarket shock or for handling or just for looks? FZR's seem like they're already really low to me. I was on tip-toe to reach the ground with both feet on my CBR600 of the same year but I sit on this thing like it's a park bench. Maybe I should check if a PO lowered it.

Most people are using custom dogbones to raise the tail back up after the install of a newer R6 shock.

BTW, Stock dogbones are 6mm (1/4" is 6.4mm) mild steel that is stamped out for a few cents and there is still gong to be a massive safety factor on those. I'm pretty sure that the dogbones used on the R6, that the R6 swap shock comes from, is the same thickness or only slightly thicker but aluminium. With the adjustable dogbones how about making a set like this? One end is left hand thread and the other is right. This allows for minute adjustments and the dog bones don't have to be removed to do it.

Bueno, yo con lo que ustedes llaman huesos de perro, no me la jugaría. Es famosa la anécdota hace ya muchos años, que el piloto probador de la Benelli Jarno de 125 cc casi se mató en la prueba para una revista al romperse una bieleta de esa parte del chasis, o sea que....Si yo me quisiera hacer algo regulable haría los extremos con bieletas articuladas macho roscadas de 10 mm y unidas a un tubo roscado en ambos extremos a 10 m.m. pero NO un tubo cualquiera sino tubo de acero si puede ser de cromo molibdeno, con lo cual girando el tubo y luego bloqueando con dos tuercas a cada lado del tubo obtienes la altura deseada. Me horrorizo sólo de pensar que se pueda romper esa pieza en marcha. :yikes:

Hi
this will have to be translated by Google for you to make sense of it.
Ducati has been using alloy dog bones of the adjustable type for years, I know because i used to cut them in half to adapt them for racing floating brake systems on older style bikes where the original system would actually lock the suspension under heavy braking in a corner when you have your knee down and you need aworking suspension so the rear contact patch does not break free of the track surface.
see half way down the page at :-

Hi,
este tendrá que ser traducido por Google para que usted pueda hacer sentido de ella.
Ducati ha estado usando huesos de aleación de perro del tipo ajustable desde hace años, lo sé porque yo les reduce a la mitad para su adaptación para las carreras de sistemas flotantes de freno en las motos de estilo antiguo en el sistema original en realidad bloquear la suspensión al frenar con fuerza en un esquina cuando se tiene la rodilla hacia abajo y que necesita una suspensión de trabajo por lo que la superficie de contacto posterior no se desprende del conjunto de la superficie de la pista.

Hola, bueno yo he tenido que cambiar los huesos de perro de mi Yam fzr 600, no porque se rompan, pero con los kilómetros los agujeros que van unidos a la bieleta de suspensión, se van haciendo más grandes y la suspensión coge holgura. En mi Yam, estaban casi cuadrados. Conviene revisar.

Hola bien mío tiene 18 mil millas con ellos y hasta ahora no llevan, pero luego el dueño anterior y que son conocidos por hacer controles periódicos de seguridad y mantenimiento regular. Contacto ReelRazor o ThatKid en este Foro para los reemplazos. Cosa que usted podría utilizar aleación T6 de grado o de acero inoxidable si le gusta cosas brillantes.
