YAMAHA MR80 ระบบกันสะเทือน / โช็คหน้า / อื่นๆ
It was equipped with a 19/17 inch wheel which was larger than that of the MR50. It coped with its power by adopting a square cross-section swing arm for its monocross suspension.

Normal muffler - External system outside NORMAL installation dimensions can not be installed unless the hole of Flange is processed.
Included G / When assembling using K, Piston comes out from the upper end of Cylinder. When assembled with Takegawa 117 Head, Piston hits Head. (Crank is NORMAL)
Cylinder and Oil pump hits.
It is like this when 5FA1.
Bore up to 71 cc, so purchase it at the same time - I installed it. Because the compression ratio has not been raised, the original net STD Nut will be enough, but since there is a sense of security that you think that this one is durable, purchase - I am satisfied with the installation.
In either case, we may do some kind of processing.....
The cross sectional area is smaller than the two leaf Reed Valve, but at the maximum speed the six leaves grow longer.
The attached Inmani Rubber is not good durability Crack cracks soon.
However, unlike Mani, a man of Bolt, like KOSO Mani,
Fiber-filled Radiator hose for for Vehicle can be diverted, so I prefer this man in this shape.
Manufacture of details is a bit nuisance but Mani and 6 leaves Big Reed Valve are set and this price is bargain.
The KN Planning Bore Up Kit With Head is a good quality bore up kit. I cleaned up the porting on mine a little and skimmed a little off the head with sandpaper and a flat surface. Combined with a PWK28 carb, V force reeds and a G03 exhaust it's an awesome setup. Plenty of parts support if you pop a piston or need rings... Like I did. 57MM go!
