IKK Cylinder kit 177 Racing YZF R125 - MT125 V1-V2
The IKK cylinder kit has a 62mm bore, offering a displacement close to 180cc, and it will fit perfectly on your Minarelli LC 125 4T high engine (YZF R125 2008-2018 and MT125 2014-2019).
To complete the assembly, the original cylinder head must be kept because of the original valve imprints on the piston, but it will be necessary to carry out the usual checks in metrology for squish and valve/piston gap, in case you put a tree Has Racing cam type Fasstek C3 or UMA R3.
The cylinder benefits from a ceramic treatment in order to offer better resistance in all possible engine speeds, and from a forged piston with a dome having a surface treatment to resist knocking. With an adequate intake and electronic engine configuration, it is possible to approach 18 HP!
The IKK kit comes complete with cylinder, piston, rings, rods and pin.
Please note: you must purchase an additional set of seals in connection with the cylinder which will be offered to you as an option.
LAB Fast125 Tech Tips:
We recommend adding a Racing oil pump and fitting a new timing chain. (see also chain guide pads)
It is possible depending on the version of the engine that the cylinder requires a Manual FST timing chain tensioner, for this please look at our photo in comparison with the one that is already mounted on your machine.
For the replacement of your cylinder you will need to provide for the dismantling of your cylinder head and the ancillary connections.
Before reassembling your high engine, we advise you to check your squish and the valve/cylinder head/piston gap with your camshaft and to torque tighten the 4 cylinder head screws, the tightening of which is 22Nm, and for the 2 screws water pump side at 10Nm.
For motorcycles with high mileage, we recommend that you purchase a water pump repair kit and cylinder head screws!
We also recommend that you put an adequate injector in relation to the engine capacity and well-proportioned intake accessories (throttle body, air box fitting, air filter, fuel pressure regulator, etc.)!
We advise you to put a Powertronic programmable ECU in order to refine your engine tuning.
A forged connecting rod or a crankshaft with forged connecting rod and recommended for engine reliability!
