Hello I've just got some minispares hi lo's ripspeed.
I see they've gor holes on the side .
Do I have to cover them up with tape to avoid water going in or should I leave them open?

You will find they are for lubrication I'm sure. Allows oil to be added to the threads, I can't picture the said HiLo trumpets, a while has passed since I last used a full set of the RipSpeed on a subframe build.

 

I religiously used to cover the threads of HiLo in grease before assembly. One thing you can do is use small rubber bungs to stop any ingress of water, but as long as there is oil or grease as lubrication, you should not hit any issues. Steel and aluminium don't mix very well with water

You have put a picture on while I was typing away.

 

I can see some grease there - so a good start - but you can use some rubber bungs if you like. Bleed nipple covers reversed is just an idea

It's a water drain hole on my 80's type Ripspeed hilo's.

Thanks ??

I always thought that the holes were there so you could put a screwdriver in to prevent them from turning when adjusting the threads. In the case of the front ones the water would have to get to a pretty high level for it to work as a drain

Don't know what the new ones are like but on my old allen key only adjusted ones that are pictured, the drain hole looks high externally but internally it is at the lowest point at the top of the internal screw thread.
Picture shows internal shape and why the drain hole appears so high.
