Hi, my name is Burak from Turkey.
I am 30 and i am living in Istanbul. I have Suzuki DL650 and Kymco Agility City 200i.
I need some information tuning the scooter.
I've done some research about stroker crankshafts, BBK, variators and ex. I found what i need about transmission. Agility City 200i fits Dr.Pulley 181401 series but i am confused about the engine type.
This engine 163 cc, 60mm bore and 57,8 mm stroke, same like GY6 engines but i am not sure about that does either the taidas 3,5 mm stroker or hoca 2,5 mm stroker fits this engine.
There are a lot of information about 157QMJ, 152QMI ex, but this engine series KF40AA.
Can you help about me.
Thanks

SylvreKat thanks your welcome. Actually i want to increase the compression ratio and tune the whole transmission system. Variator, clutch, clutch bell, torque drive, aluminum half pulley, torque spring. In this case i think i got most efficient power tranfer from crankshaft to rear tyre. If i can increase the compression engine will be more powerfull and quick throttle response.

apparently nobody here has an answer. if haven't figured it out by now i would try calling your supplier. occasionally you'll get a knowledgeable employee. if scooter elements was still around he would have info and parts for you.
what happen to him?

I'm not familiar with that engine . I really don't know if the parts for the basic gy6 will fit or not ? Sorry bud wish I could help. I did a little research but I could find a clear answer.

When it comes to the variators . it seems as if the agility 200i and the 150 gy6 variators are interchangeable. I'll see if I can find out about the top end kits.

Thanks a lot for your helps. My scooter is www.kymco.com/product/overview.asp?MotorCTID=DDF33213-B58A-4371-9271-D3E58AEF2C95In this site's part catalogue the crankshaft oem part no 13000-KFB7-405, as you can see actually 13000-KFB7-405 same as 13000-KFB7-900, it's only have extra KEY WOODRUFF (90701-HFB6-C00). 13000-KFB7-900 is 150 cc GY6 kymco engine's crankshaft oem no. I asked kymco dealer in Turkey about this sutiation, they dont have enough information, said that only the cylinder is same as GY6 57 mm spacing. So if i want to buy a BBK there is no problem but i want to buy a stroker. Because compression ratio is too low. what the 9.5:1. I am not use this scooter 400.000 km, who needs low compression ratio like this. 12:1 or 12.5:1 acceptable ratios maybe occurs more vibrations but it is not problem over 3000 rpm. Finally if i wont find any solution i think i shave cylinders head maybe 1 mm. I want to tell why i am doing this. There is no problem accelerate from 0 to  km/h, after that suddenly power is gone and 105 km/h end of the track. On downhill 110 km/h. On km/h i only twist quarter throttle, on 100 km/h maybe half throttle but i give all there is no speed, rpm is rising but speed not. So consumption is high around 3 liters one person 80 km/h, two people 3.3 liters same speed, on full throttle over 4 liters. |

geh3333 yes it is fuel injected. To be honest, I would not worry about the stroke . I'd get a nice 63+ mm bbk and a nice free flow exhaust " if it doesn't already have one " and a free flow uni filter. I'd also check on taller final drive gears. Since that baby is efi , you will be running in the 70's for sure " on straight runs " maybe even close to 80mph! A good CVT tuning with the taller gears , free flow air fuel system and the bbk ! |

Does it also have an oil cooler ? |

No, it has forced air cooling.

If your rpm is going up with full throttle and speed is not increasing you have slipping in the transmission ,,, either the belt is slipping badly or the clutch is or the variator is not closing all the way so the belt is not going up as far as it can
