Now the days are getting cooler I have noticed that my coolant temp has started to drop below what I would like.

So I have made some radiator covers to bring the coolant temp back up to a better level.
They only took 10mins to make, (kind of self evident ), out of an old inner tube. They can be easily removed, without tools, as and when required.

I tested them today, the air temp was 14c-16c (57f-60f) and successfully increased my coolant temp, keeping it at between 74c-80c (165f-176f) whilst riding.

There is still a reasonable cooling effect from just the air flow over the engine, this is more noticeable when riding downhill.

When stationary, at these air temps, the fans are still able to draw enough cool air through the radiators to reduce the coolant temp and stop the engine overheating.
