Heat Radiation Fin

It looks very clean and the silver shine matches the SR400! I think the silver shine is also suitable for the SR400!
You'll need a Glasses Wrench, but it's easy to install
(The size of the original Nut and the Nut that came with Heat Radiation Fin are different

It's more of a heat dissipation effect than a cooling effect, but I think it's helping to dissipate heat because it's getting hotter
I don't use the Oil Temperature Meter, so how well it works is a mystery to me I feel that the heat dissipation is better than NORMAL

At the same time we installed Heat Radiation Fin of the 1st stage and the 2nd stage. Installation is easy, but it is regrettable that Torque of Nut tightening was not described in Instruction Manual. After installation, the high-pitched sound is mixed in Machine noise of the running Engine. I feel that comfortable vibrations have increased slightly. If you run on the same Route as usual the oil temperature is 5 to 10 degrees lower. I am looking forward to next summer..

Looks cool.

In the picture, both the Heat Radiation Fin and the first tier have the BORE ACE Logo, but in reality, there is nothing and it looks cheap.
I don't think it absorbs enough heat to feel the effect either.
It seems a bit high in terms of Gold amount.

Installation is easy. I run the same Route at the usual temperature and the oil temperature is 5 to 10 degrees lower. We installed Heat Radiation Fin attached to Cylinder head at the same time, so we can not identify which effect it is. What is mysterious is that the machine noise of the running engine after installation is a sharp sound. I understood well that there is a cooling effect, but because the price is high, Cospa made the star 3. It is regrettable that Torque is not stated in installation Instruction Manual. To

I wanted to manage the oil temperature of SR 400 in some way.
I tried it at a temperature of 29 degrees Celsius, at a high speed of 60 kilometers and a 30 km downstairs.
As usual it is oil temperature 95 ℃ ~ 105 ℃, but after wearing it is roughly 90 ℃ ~ 100 ℃.
It will change with such Small Parts ~.
Oil temperature is 【Go down】 Instead, I can not rise. Feeling.
After running, it was getting hot enough to touch with bare hands w
He will dissipate heat well.
