Your Chinese Dual sport picture thread

I post new topic about this bike, I though this thread should only show up the bike.
Apologize for this.

• The 163FML engine featured a single-cylinder, four-stroke design.
• Total piston displacement of the engine was 197 cc.

• Featured a five-speed, constant mesh transmission and a chain final drive.

Engine Performance

• The 163FML engine had 16.76 horsepower at 8,500 rpm and 11.1 foot-pounds of torque at 7,000 rpm.
• Due to the modest engine size, the top speed was a timid 75 mph.
• The idle speed for the 163LFM was 1,500 rpm

I will pick up the bike around Sep 5/2011 with the register plate. Prior to this, I have to do some home work.
I was thinking on the cosmatic and performance, i.e.
-New allloy rim (I may get from Honda AX1) with dual purpose tire (Similar to BMW GS)
-Alu swing arm
-Rear shock with sub tank
-520 chain with 15/42 sprocket (May be 428 heavy duty high strength)
-Let see how the clutch respond, if not will change clutch plate/clutch metal plate to Honda brand.

With new final drive, I have to do some modify on the VE (Velumetric Efficiency) to have a better performance.
I was thinking to increase compression ratio to 9.5 to 10 : 1
Change the fuel system by using new Carb from Keihin PE74 that belong to Honda NSR150
and change main jet to around 120 and slow jet to 32
Fuel using will be E10 and E20. I may tune the fuel to use with E85 in the later stage.****
As I am living at the sea level, I have to re-tune fuel (Carb) anyway. Change carb is the most easiest way to me.

I want to have a higher touque and HP, but I want to limit the high rev to 8500 rpm.
This will save the engine life. Later stage to have a bigger forge pistol and do some large valve.

I was thinking to hit 130 Km/hrs@8000 rpm with this mod and final drive as below chart speed.
Last before I forget, Engine oil is the most important to me. I will use 100% Synthatic from Valoline
15W-40 API-SL. I use this oil for all my motors. (FullPressureTurbo Engine, motorcycles)

Thanks for reading
