Points of Attention

I used old and new with NS50F. Construction is Normal chamber of the previous term (Good coming off) , Normal cab almost NORMALSpec. is.
Long ago in RiderComics' verification article, it was the evaluation that Kitaspa was the most good Kit I bought it. At that time I remembered that it was around 8000 yen. At that time it was quite famous, it should have sold quite a bit for Light user.
I bought that kit of the time at that time and the same kit as the current one and used it. Early MODEL was cut to Large Big near the center of PistonHead, Currently the processing of Tana part of Piston has become. In terms of performance, the compression ratio is high The current worries of the detonation are also less is good.
Installation is not a problem at all. Especially it's ok with elementality without chamfering. Both old and new very accurate and high quality.
With Base & Head Gasket and Set increasing compression and changing Port timing, Because we change the exhaust port timing considerably large, the power band is considerably higher to change. I think that it will become low-speed squirrel if it is Big carburetor, Normal cab is fine. Automatic boy basically also has Normal cab If you are recommending, if you finger Large, you can use your own Head kit and so on like Components Please use it. "Rigorous focus on Balance" Because it is the attitude of, strangely here It may fail if fingering.
As the power band rises, the compression also increases, so it's normal to have a Trolley ride Feeling that you can not feel so much. But, if you give up giving me Axel, it's frightening It will accelerate. I get speed so much I can not say (Lol) It's probably the way it will be if you hit Timing this much, but Piston and Gasket I am surprised that it is only realized. If you are a Mission car like the NS50F you can use the power band which it rose effectively, With Scooter you must set firmly Hypli and Clutch, you can not survive the rotation It may just be a motivational experience. Only there needs attention.
As compression increases and packing efficiency improves, the water temperature rises in the summer. Normally, it falls within the design range of Manufacturer, so there is no problem.
There is no particular problem in durability. Both old and new seems to have durability of NORMALLevel. It can be used with confidence "Weird Piston kit". it's recommended.
