【KITACO】High Comp Piston Set (50cc Exclusive) Review

Genuine Kitaco Complete Piston Set

Along with some other parts for this mega rebuild/project bike. The pistin was shot due to not being stored correctly and was eroded in places. Not to worry, I found the right piston set pretty easily and the price was to be honest, amazing for what you actually get. The cost of shipping was really good value too which made my life a lot simpler. I did have a few other parts ready for ordering and got them all shipied together with EMS and my order arrived in 5 days. The box my order came in was well padded and nothing got any kind of damage in transit. The piston set comes with the piston, the rings, circlips and the gudgeon pin so all you have to do is fit it and away you go. The piston is weel made and I had no issues fitting the rings which had enough flex to negotiate the piston correctly. All together, very pleased with this purchase and an absolute bargain too. Thanks Webike, very happy View detail

People who want to be concerned about 50.

I have been interested in it for a long time.
This is a high-compression piston that aims to increase power by increasing the compression ratio without changing the engine displacement volume.
I assembled it with 50Engine for Spare.
I was worried so I put in High Camshaft for STD Head.

good point
It is different from NORMAL.

The Exhaust System is also NORMAL and the carburetor is still NORMAL and Large sturdy.

Easy to replace since only the piston is changed.

It is more durable than Bore up.

A bad point
● Compression will increase, so you will have to change the fuel to Regular→ High octane or it will break.

High camshaft is required; normal cam will not turn.

It will be a maneuverable spec. for those who want to use CUB, Race, 50, but want to use Yellow color Number, and so on.
I think it's a face white.
When my current 88 breaks down, I plan to load up a High-compression 50 and play with it. View detail

Installed on AA01. It was more than I imagined.

I'm a hobbyist, but I've been playing with CUBEngine for about 20 years.
It's easy to lose the CUB transversely installed engine above the waist like a plastic model.
Take it slow, it takes about 30 minutes to get to the Piston and another 40 minutes to assemble it.
With the combination of PB16 and C90Cam, the increased compression increases the slow torque and
Thanks to the Cam, the high RPMs turn well.
I think it's for people who want to pursue it as 50, and is somewhat for professionals.
It's only 50? so you won't get a torque like Bore up.
If you really want to go faster, I recommend Engine Displacement VolumeUP instead of this.
After 8,000 miles, I felt the Piston ring was worn out so I opened it up again.
Piston rings are two rings, so they are not as durable as three rings.
I replaced the new one and the low speed torque returned considerably.
It's hard to notice because it degrades a little bit, but the Piston ring degrades at about 5,000 km.
I think you should replace it.
The Piston itself was very clean with no scratches, and some of the WPC processing worked!
I think. And I have found the Piston machining accuracy to be good. View detail

Required to power up with 50cc

[1] Reason for purchase
The 50cc engine is designed to meet the regulations of the race In order to power up while sticking to the Displacement Volume, this I chose the High-compression Piston
For example, comparing MONKEY and MONKEY R, the same Engine Displacement Since Piston, which has a higher compression ratio, is used to produce power with volume We aimed to achieve the same effect
In addition, the combination of the Carburetor's large diameter and high camshaft makes it possible for you to use the Carburetor in combination with In order to achieve higher RPM and more power, we proceeded with tunings

[2] Installation
Even though the CUB-based Horizontal TypeEngine, which I've opened several times Installation was still quite a challenge
I had to replace the Carburetor and High Camshaft at the same time, which took about 5 hours It took

Still, I didn't have any trouble with the Manual and lots of information for installation
Since this is the same work as Bore up, I also prepared a torque wrench and so on

And since gasket stripping is a standard part of this kind of work, it's standard for this kind of work to be a pain in the ass Get a good Scraper! (I used KTC's in this case.) 。
You will be able to work much more efficiently

The installation of the Piston is nothing special, but be careful not to blow the Pin But it's also standard to skip it ^^^;

[3] effect
From the KICK stage 'Oh? Something's different and a higher compression ratio
The way the engine turns around is very sharp, especially in the mid to high RPM range is completely different - Circuit's Straight shakes off the OEMMeter!
I made the Carburetor large and added a High Camshaft, which I expected When it comes to street effects, it's true, but I'm not sure how much of a difference 50cc of CUB-based engines can make and fun to ride

However, because of the higher compression ratio, Gasoline goes from Regular to High Octane
It's a GS and a CUB High octane I'm a little embarrassed to say it, but I'm convinced that it's a trade-off for performance ^ ^
Of course, Gas prices will also go up a little bit, but since it is a CUB that only holds a little bit more than 3L in a full tan It doesn't feel too painful

However, the Bore up will be the better choice in terms of cosmetic value For the same price, the 75cc engine characteristic of the torque will be fatter and easier to ride I think it will be
For those with a license or a penchant for 50ccs, there is no question about it I want to View detail
