Fox vs good quality aftermarket oil

[jugheaddave]

Hi

 

Any know issues with using a good quality motorcycle shock oil in the damper side (of the correct weight) vs original fox oil to service my shock

 

I understand float fluid is float fluid, but I am talking about the other side?

 

 

Thanks

 

Have a nice day.

There are no issues with using good motorcycle oil. In fact, Fox gets its oil from one of the oil OEMs - Lefty can tell you which.

 

Further, Fox uses 7wt and motorcycle oil companies only make 5 and 15 wt (from what I can source).  Use 5wt in the damper. At the very worse, the effect will be a slightly different setting on the damper. If your favourite position was at 2 O'clock, it will now be at 3 O'clock. That is, if you can really feel the difference.

 

 

As for the float fluid - just use thick gear oil. Use any of the hypoid products from Castrol etc. 80W90. If you don't feel like buying 500ml of yet another bottle that willl gather dust in your garage, chuck some of the damper oil onto the air piston. The only difference is that it will work through to the bottom a bit quicker and you have to top it up more frequently. Rox actually specifies damper oil for its piston fluid.

 

The branded Fox oil is ridiculously expensive - something like five times the price of that same product on the shelves under the original name.

Hi

 

I managed to find 1l of belray motorcycle 7wt oil for just under R100-00.

 

Any one have a link on a guide to servicing a 08 F100Rl.

The Oil used by Fox is Torco RSF Medium and Heavy. Often these are blended at 60/40 to achieve the 7.5wt.

 

as mentioned in the big Oil discussion in the Tech Q&A, viscosity does not blend linearly so Log-log rules need to e applied to calculate the final viscosity of a blend

YAMALUBE less than 100 bucks for 500ml and I know many Technical guru's use it, at laney shops. Get it from your Yamaha dealership

thanks guys.

 

I bought my seal yesterday, and got some float fluid.

 

Anyone got a link to a decent guide??

Self-taught myself off this site some time ago. I see it has just been updated, just choose the relevant model and click ahead.

There is a reasonable guide on the Realworldcycling.com website.  I saw it there a week ago. Search around a bit, it is in an obscure place IIRC.

If there is a thread on how to mix suspension fluid I will appreciate it.

Just beg Lefty to explain it again!! Or do an extensive search on the Tech site...it's been covered quite well some time ago...
