【Workshop Kitamura】Clutch Retainer Kit Review

Used for TY250

I used it on my Yamaha TY250S.

Normal clutch inevitably feels slightly slippery and
When I was thinking about what I could do about it, I found out about this product and bought it.

The clutch spring was also replaced with a 4mm longer one, and this product was also assembled.
We did not include the included Washer.
I didn't feel it was particularly heavy or anything.

I connected the clutch as before and the engine suddenly stalled.
Clutch has a nice on/off feel to it.
Of course, there is zero sense of Clutch sliding! 。 Large Satisfied

Kobo Kitamura Clutch RetainerKit KITA-Y12-01

[How is it used?

Was the one you received as per Image?
The product and Quality was exactly what I expected.
Was the installation difficult?
It's not difficult if you have a Kill. If you follow the Manual for each of those vehicles, you'll be Large strong.
How was your experience with it?
It came with 12 Shims, but I installed them without Shims this time. Clutch operation became a little heavier, but not too much. The distance between the lever and the clutch is obviously shortened. In other words, it is possible to meet with short stroke. The symptom of slipping at high rpm is also eased and it became like Reinforced Clutch.
[Included Parts:were they on?
12 Shims for adjustment, with 3 levels of adjustment
[Was there anything that disappointed you?
None at all

Clutch drastic change

I was wondering if I could do something about my carburetorSR clutch which is said to be heavy, and found this.
It is MAJOR to put in the clutch spring of the fI car, but because my SR is tuned so much and has more power than NORMAL, I had been hesitant to change the spring because I was worried about the durability.
The number of Washer between Retainer and Spring can adjust the strength of Clutch, and the recommendation is 2 or more. I made it to the number of sheets.
It's not only lighter, but it's also a lot quicker than the OEM clutches. I like the Feeling Ring very much, but it may be a little confusing until you get used to it because it is completely different from the way the OEM Clutch breaks. If the OEM Clutch's Stroke is 10, this one is shorter at about 6. (Of course, the Stroke of the half-craze will also be shorter.)
Clutch work is much better and shift is much better. Also, this may be just my SR, but I can say that the slight vibration from the engine has been reduced. (Because it is Front cowlSpec., the swing of Screen became Small.)
I think it's a really effective Parts for the Gold price! View detail

It feels good to hold the Clutch lever ~.

I bought a Clutch spring retainer from Koubou Kitamura.
Yamaha's RZ250R also fits, so I installed it.
When I held the Clutch lever, it was very smooth.
When I dropped the GEAR by one step while driving, the connection softened the Shock.
Cutting and connecting the Clutch is very sharp.
I niggle the Clutch lever for no reason. [Laughs] View detail

It's a spastic cut and the lightness is adjustable.

[How is it used?
I am playing with Enduro on YZ250, and I am not good at speed type, so I often play hard type.
In addition, I was worried about it because I often run Narita, Katsunuma, Whiteui and other courses that require clutch work in practice.
I've never baked Clutch work before and I'm not bad at it, but I'm just not good at Front up, so I bought this one.

Was the one you received as per Image?
As per Image, I increased the number of Washer 12 to 18 which can adjust the Clutch pre-road.

Was the installation difficult?
I replaced it while it was on the MotorcycleLift because my back was hurting, but I think it would be easier to install it in a sideways position.
It is Washer for pre-road adjustment of Clutch Spring, but I was told by Mr. Kitamura that 3 pieces are good for YZ250 and 2 pieces are good for YZ250X. Because my YZ250 uses the Clutch Spring of YZ250X, I made two pieces.

How was your experience with it?
I installed it before the race and ran it on the track, but it was so different that I was confused.
MeatPoint and the way we connect has changed.
I'm sorry for the onomatopoeia, but it's like a quick snap and a quick connection…lol

[Included Parts:were they on?
Sticker comes with it. The cat is cute.

[Was there anything that disappointed you?
None!

You shouldn't do it right before the Race because the Fee Ring changes too much. Do it before going to practice lol.
Also, when I installed it, I loosened the bolt half a turn from tightening and grabbed the Clutch lever a few times to center it and then tightened it. It's just my feeling. View detail
