Description
This is a pre-assembled lower back engine kit that allows you to change from a secondary kick arm system to a primary kick arm system for the Monkey and Gorilla engines.
You can convert your current SP Takegawa cylinder heads with auto-decomp (except Desmodromic Twin Cam 4V) and 124cc kits to the primary type by assembling them to this half combo kit.
This service is available for those who have already purchased or are currently installing various types of cylinder heads and displacements on their vehicles.
■Details (attached mission: S Touring 5 speed)
This is a pre-assembled lower back engine kit that allows you to change from a secondary kick arm system to a primary kick arm system for the Monkey and Gorilla engines.
You can convert your current SP Takegawa cylinder heads with auto-decomp (except Desmodromic Twin Cam 4V) and 124cc kits to the primary type by assembling them to this half combo kit.
The half combo kit is assembled by SP Takegawa mechanic with proper control of each parts.The primary type kick starter system with parts list allows the engine to be started by disengaging the clutch no matter what gear it is in, and is recommended for racing use where a quick engine start is required when restarting.
In addition, in the case of the primary type kick, it is transmitted to the drive gear without going through the transmission, thus reducing the load on the transmission when starting the engine.
[Half Combo Kit Features]
Newly designed SP Takegawa original reinforced crankcase
SP Takegawa's original reinforced crankcase is a high quality crankcase specially designed to increase the rigidity and detail of the crankcase.
The oil pump is a crankshaft direct drive oil pump.
Compared with the chain drive type reinforced oil pump, the discharge volume is about twice as large.
In order to reduce the internal pressure of the crank case of the large displacement engine, the inner diameter of the breather pipe is 6mm instead of the stock 4mm.
The crankcase body is equipped with an oil jet mechanism that constantly sprays oil directly onto the small end of the connecting rod and the backside of the piston for lubrication and cooling.
The transmission bearing is equipped with a special bearing hold plate for big torque.
■Reinforced clutch
The reinforced clutch uses 5 discs to eliminate clutch slippage that occurs in high power engines.
Wet special clutch only, magnesium die-cast cover.
The clutch cover used for the wet clutch is a patented clutch cover that allows for the installation of a thermostat.
Overcooling can be prevented by installing a thermostat unit (sold separately).
Furthermore, an oil outlet is provided to allow oil to be taken out to the oil cooler.
■Stroke-up crankshaft
Special bearings with a larger inner diameter for the journal bearings of the stroked crankshaft are used to accommodate high power engines.
The shaft diameter of the journal section, where the stress of the crankshaft is concentrated, is 22mm to improve strength and durability.In addition, the crankshaft has been given a special surface treatment to further increase durability.
■TAF 5-speed cross transmission (S Touring 5-speed)
The TAF 5-speed cross-transmission offers high durability and excellent operability.
[gear ratios]
First gear: 2.357
Second gear: 1.611
Three speed: 1.190
Four speed: 0.958
Five speed: 0.807
■SP Takegawa original aluminum die-cast generator cover.
Separate type drive sprocket cover is adopted, and sprocket can be replaced by removing only the sprocket cover without removing the generator cover.
■Kit Configuration
The kit is for primary type only.
Reinforced crankcase, cross transmission, wet special clutch, magnesium die-cast clutch cover and crankshaft for each displacement are assembled.
Also included is a 910mm clutch cable, 1000mm breather hose and 2 clips.
