I built it when I was doing Race at NSF.
The price was low, the overall power was high, and I was satisfied with the Large change. There were no particular problems.

good budget upgrade

This kit is a good budget upgrade kit compared to the stock displacement. It also can be used with the stock cylinder head without clearance issues.

First time Bore Up Kit

Purchase for OEM 100cc power shortage.
It is a product that can be powered up quickly and cheaply at the price.
We asked to install Motorcycle shop, but it was quite hard to fit the Piston ring. It seems that Piston ring diameter is slightly harder than Piston.

Spec. Perhaps, though, Piston has been playing in Cylinder all the while.
We used about 10000 km, but the noise increase Large and Oil rise etc etc. There was no trouble, it ran in No Trouble till the day to remove it.

Do not defeat Grom

XR 100 MOTARD, but when running with Grom, the difference between 25 cc Torque is large, and the difference between Large and TopGEAR is released. With this, I decided to turn 115 cc.
115 CCKit comes from each company. Takekawa, KITACO used well so far, so I tried using SHIFT UP this time. Although the price was uneasy because it was cheap, the Kit delivered was also polite Packing, also included IntakePacking, Exhaust Gasket All in one was.
Piston who was most concerned, but was tackling the weight reduction with the fashionable ShortSkirt, only a few grams Up with OEM weight. I thought that this could be expected. The thickness of Sleeve is about 1. There are only 3 mm and OEM half, but since 100 Engine was originally the only Sleeve thick, 115 companies will be able to leave each company's thickness to this extent. I am a bit worried about durability.
I am a bit worried about making Oil Ring. It was my first time to incorporate Oil Ring.
Piston assembles after chamfering with water-resistance paper. Because Sleeve is thin, I only care about the incorporation of Cylinder while reducing Ring.
If you are familiar with the APE Engine Engine well, it is usual accustomed work.
Oh yeah, we can not do Bore up work unless you drop APE Engine out of the car body..
Incorporating 115 Kit, incorporate Reinforced Camshaft Chain, Reinforced ClutchSet as well.
YOSHIMURACam + 115cc + I think that the power of PC20 is what it is, KICK, but I do have trouble starting to see if the setting of carburetor is not met. It finally started, but it is too dark totally useless. Main jet, Jet needle Changing the number of stages a few times, Finally Setting goes out.
Acceleration can clearly feel 15% Up. I did not want to open fully without accustoming, but I wanted to see the Carburetor setting in the high speed range, so reaching 100 km comfortably turning it up.
The GEAR ratio is F15, R32, which is slightly higher than the OEM, but if you match Axel well with low GEAR, the Front will float with just Axel, but if you are enjoying Front up, the enhanced Drive chain of 420SR I got stretched.
Engine which has considerably increased power than NORMAL seems to put a burden on the driving system. I am also having durability worries and I will not stop browsing too much.

[Webike Monitor] Since the Cylinder and the Piston had become full of cracks by for the first time in [ a head ] although the Bore up kit of the
DAYTONA was used, it exchanged for the product made from the cheapest SHIFT UP.I think that Cost-performance nature is very high.Although it can say to every external article, since the skirt part of a Piston is short, the Katha Katha sound by for the first time in [ a head ] is worrisome at the time of an Idling.It seems great difference [ neither the engine performance nor durability / any Manufacturer ] if a Plating cylinder is removed.
