*Specification changes when purchasing a complete engine
・It is not possible to change the specification of the engine other than the engine specification set by SP Takegawa.
*This product cannot be installed on Monkey (injection vehicle).
*Always use high-octane gasoline as fuel.(Knocking or other drubbing may result in an accident.)
*When installing a 124cc / 138cc complete engine: Since the engine length is longer and the stock front forks, top bridge and steering stem interfere with the tires, the front end needs to be modified.For monkeys and gorillas, we recommend installing SP Takegawa's various front fork kits at the same time.
・When installing 138cc on a vehicle equipped with aΦ30 front fork kit: Specified steering wheel & top bridge set (Part No: 06-02-0015).
・In the case of SP Takegawa's 2 piece front fork kit (for 10 inch): It cannot be installed at the same time as the DOHC 4V+R138cc because the fender interferes with the bed.

*Complete engine recommended parts
・Need to change to big bore carburetor
With the change to the DOHC 4V+D cylinder head and the increase in displacement, the Big Bore Carburetor Kit that maximizes the performance of the engine must be purchased separately.
SP Takegawa's carburetor kit includes the carburetor, special manifold (insulator), and high throttle set (FCR / TMR downdraft only).
You can choose from four types of carburetors: MIKUNI VM26, KEIHIN PE28, KEIHIN FCR downdraft, and MIKUNI TMR downdraft.
・Need to change to SP Takegawa exhaust which has excellent exhaust efficiency
In order to get the best performance out of the engine, it is necessary to change to an exhaust with excellent exhaust efficiency.
In case of DOHC 4V+D cylinder head, it is necessary to purchase SP Takegawa's special exhaust for DOHC 4V+D.(Bomber Exhaust / Hyper Street Exhaust / Racing Exhaust)

*Precautions and recommended parts when purchasing a complete engine
・No engine oil is included.The engine oil must be purchased separately and filled by the customer.
・The kick starter arm is not included.The kick starter arm made by another manufacturer may interfere with the clutch cover, so it is recommended to use SP Takegawa's forged steel kick starter arm (chrome plated part number: 02-08-0052) is recommended.
・In order to get the best performance out of the complete engine, the recommended bog bore carburetor and exhaust are required.
・Since the overall length of the engine is different between the stock engine and the complete engine, it is necessary to change the body from the stock body to the one recommended by SP Takegawa.

*When you purchase a complete engine, you may be asked to fill out a pledge form.
*There may be changes in product specifications due to the manufacturer's reasons.

* Please note in advance that cancellation and/or return of this product cannot be accepted once the order has been placed.
