Hello all,
Almost 3,000km ago I bought this 125cc scooter, compared to other scooters and motorbikes I owned, this one is nearly perfect. Currently I work and live in Beijing, China. The local government created a lot of restrictions for the two wheelers, for example biggest _legal_ motorbike engine you can find here is 250cc, while biggest scooter is only 150cc. Having a car in this city is a pain in the "back", even with OK gas prices.
My scooter does surprisingly well, I can easily maintain a speed of 95-100kph (uphill 90-95) (checked with friend's car, and my speedometer is showing about 5% faster), and have enough acceleration. The
problem for me is the small acceleration drop between 40 to 50kph.
It's a Suzuki scooter with Japanese parts assembled in China. This scooter have a lot of different names, like Vecstar, AN125, VS125 and mine: HS125T or Neptune (HaiWangXing - 海王星 in Chinese)
Here's what I know about the version I own:
Length x Width x Height 1910 x 685 x 1095 mm
Wheel Base 1300 mm
Net Weight 129 kg
Ground clerance 120 mm
Displacement 124 ml
Bore x Stroke 52 x 58.6 mm
Compression Ration 10.2:1
Maximum Power 6.7kw / 12 hp @ 7500rpm/min
Spurk Plug NGK CR6E
And I'm not sure about the following:
Carburetor Main Jet: 95
CVT Belt 760 18.9 30
Carburation: Mikuni BS26SS
What I wanted to do first was check exhaust pipe but it was not restricted, so I decided next will be the spark plug - but it's in perfect brown old-yellowish sand color, so now I'm thinking about installing free-flow air box (k&n?).
The only problem is I can't recognize some of the parts/cables/tubes going to/from the current air box and other places. So this is where I need your help
The other problems are: I'm working on the bike under my apartment building and the bike is very hard to open up (to reach carb) and so far I'm not even sure I can reach cylinder...
Below are the images with
numbers on those things I don't recognize.
Thanks!
