【POSH】Big Bore Piston Air Valve Cap Review

Repeat

Previously purchased items transplanted to CBR
I installed this one on a 92 Grom.
SealRubber is available for peace of mind.
I tried to make it a casual Accent.
It is also a good size for the cap of a light car.
I may also Repeat for Vehicle.
I thought it would be nice to be able to rotate it between Groms, CBRs, and light cars in different colors. It would be possible to use them in different colors.
Maybe it can be used in a standard car according to JIS standards, but I haven't tried it yet.
If it had been a little less expensive, it would have received a perfect score. View detail

One point of Wheel

Easy one point on the wheel and big bore piston shape.
However, there is a problem.
The valve part is made of yellow copper (copper alloy gold) and this product is made of aluminum alloy gold, which means that the screws are made of different types of gold. This will damage the screw threads of the Valve in the worst case.
One of the measures to prevent this is to apply silicone grease to the capscrew cap to protect it from electrical corrosion, considering that the O-ring is attached to the back side of the air valve cap.

Silicone grease must be applied, otherwise it will not stick. This will make it easy to achieve one point on the wheel. View detail

I like the casual PistonDesign!

[How is it used?
NORMAL's Material:I bought it for dress-up purposes because PlasticCap looks cheap.

Was the one you received as per Image?
It was as per Image, but the weight is light, solid and durable.

Was the installation difficult?
It is easy because it is a Bolt On mounted photo.

How was your experience with it?
There have been no air leaks or other problems to date.
The design is Level, which you don't notice unless you look closely, but unlike the Mischief design, it blends in.

[Included Parts:were they on?
There is no other.

[Was there anything that disappointed you?
I was worried about the color, Plating, but the paint seemed to peel off easily, so I am glad I went with Silver.

I am glad we chose POSH because there are other products with a similar design, but the accuracy does not seem to be very good, for example, there is a difference between the image and the actual product. View detail

Plating is …

Plating comes off
2) More expensive than the old Type
3．It was good that the design of the old Type was simple

So, the old Type (900 yen excluding tax) is the winner
No cheap plating parts, should have gone with Silver … View detail

Very beautiful Piston

I looked for a lot of Valve caps, but I decided to go with the Piston shape because it's a two-cylinder
The color is hard to choose, but Simple Silver is the best choice for the Piston shape Recommendation
It doesn't improve performance, but I'm happy with Fashion
