Sorry , But Yet another suspension topic,

[freddy871]

On reading all reviews back to front and sideways ,   I did a fork oil change but not being a guru feel i need help.. removed my stock oil and loaded up with Silkolene RSF 10wt which in scheme of things has a lot more viscosity.

Stock is apparently around 15 cSt @ 40C, I went with rsf 10wt which is 47 cSt @ 40C. now thinking maybe went a little too much and if going thicker has a severe adverse effect. Thinking now of dropping to Silkolene RSF 5wt which is 27 cSt @ 40C.

To be honest just grabbing at straws as really want some smoothness. Only way i can get something close  to suitable is by backing out preload fully and one click back on rebound, even then its far from compliant. now im no real heavy weight at 92kg.

Be good for opinions from those that know??? or is it time for me to bite bullet and spend some serious dosh to get this thing travelling right.

The fundamental issue with the forks is that the compression damping is too harsh as the oil does not flow freely enough. Also, the front is undersprung. (Ref Maxton view).

Heavier oil will make it worse.

Reducing front preload makes no difference, it just reduces front ride height by the amount the adjusters are screwed out.

You can only fiddle with the rebound but that doesn’t really alter the feel over bumps.

The Maxton fix, for £450ish is to change the shim stack to allow the oil to flow more freely, change the oil and fit heavier springs to support the front end under braking.

They set the rebound to suit but you can fiddle if you want.

The rear shock just moves better with thinner, high quality oil and lighter seals that reduce internal friction.
It too has reduced comp damping and a heavier spring.

The Honda shock is a robust sturdily made thing that will last but is not rebuildable and is a bit unsophisticated.

That’s all I know, hope it helps a little.

Thanks for the update, looks like I need to put some money aside for a trip to maxton or similar

I have shared this several times, but the HyperPro springs I installed in the forks and on the shock completely transformed this bike.  It is absolutely planted when riding very spirited on pavement or dirt and it is way, way better when loaded and 2-up.

Couldn't agree more. Probably not as good as Maxton, but I'm happy with the result.

What i read here about Maxton is a made to spec set and that is compared to the out of the box set from Hyperpro.
Hyperpro also offers this option but not really convenient when you're not living in the Netherlands just as it is not a real option to go by at Maxton.
Remember that the settings you get with de Hyperpro streetbox are not already set and that those settings are just a baseline. You need to tweak it to your weight and likings.
Don't know about the UK but i can go to the factory in Werkendam or one of the official dealers to have the suspension set up for free after i installed the streetbox myself.
