【Freak's PIT】SR Negative Pressure Gasoline Cock OH Kit Review

For the Fuel Cock Overhaul.

I'm currently using a KEDO Cook, but before that I used an OEM overhaul. This is the Parts that I was able to take care of at that time.
It's not a bad idea to buy a Cook as it will deteriorate over time.


good point
It is an Exclusive Design, so it comes with it except for some years.

The packaging is made of paper, which was a concern with OEM.:You can use it repeatedly because it is made of plastic.

I've been using it for about 5 years.

A bad point
●Installation is a pain. The best is definitely to take Gasoline completely from Tank and take Tank out from Frame.


It's also very durable, so once you overhaul it, you can use it for 4 or 5 years, so I think it's cosmetically sound.
It's a good part because it improves the weak points of OEM such as packing. View detail

It doesn't fit!

’85 Doesn't fit as a 1jr OHKit, the Diaphragm will somehow come on! Four-analogue Rubber parts can be used, OthersCookO-Ring shape is wrong, Tank attachment O-Ring too skinny and buried in the groove & hellip;
Only the Diaphragm without OEM Parts could be used somehow, but there seems to be some time lag to stop the flow of Gasoline because there is no hole for negative pressure release. View detail

I think it's probably Large sturdy.

Gasoline leaked from the fuel cock on my 20+ year old SR400 as it was seeping out, so I replaced it.
Since there is no diaphragm in Yamaha OEM Parts, I bought an Overhaul kit from Freaks Pit and replaced it.
As I expected, the diaphragm was torn.
For the time being, Gasoline was put in 5?Gasoline and saw how it looked, but it seems to be Large sturdy. View detail

It is a product that picks people.

Gasoline slightly from Fuel Cock
Because it was blurred, ordering and disassembling and exchanging.

I would like to tell SR members
Also in service manual
Because the negative pressure packing part is not listed
It may be better for those with some knowledge. Or remember well after Rose

I acknowledge my own shortage of Kill
After assembly, before Gasoline replaced
Because it does not stop at the ON position
I ordered OEMCookAssy.
I appreciate it with the Instruction Manual.

Overhaul of Fuel Cock Overhaul

As aged deterioration caused leakage from Fuel Cock, leakage was from the part without Manufacturer 's Single Item supplement, so we were considering ASSY exchanges unavoidably, so we found this item so we purchased it immediately.
Disassemble by removing Cook - Because it becomes an exchange, handling of Gasoline (Of course it is not allowed to ignite the fire) I think to Level's work which can be done without difficulty by replacing it with care.
Only Hexagonal Wrench and Phillips Screwdriver are necessary tools. It is even better if you have Brakes cleaner for cleaning and RubberGrease to apply to Rubber packing classes.
Although it may not be necessary if it possesses an exploded diagram etc, there is no attachment of Handling Instruction Manual, so it is recommended to arrange parts to be disassembled in order to replace Smooth To do.
I felt that the resin Washer was also attached to Product Contents and it was kind.
Note) Rust on the screw head (Especially Plus screw) If it is occurring you should work carefully so as not to crush the head. View detail
