Hi all,
I have a 2000 Speedfight 2 50cc which I bought used. I have installed the:
Eco kit POLINI Peugeot Buxy/
Art.-Nr. P2415102
With the 7 gram rollers. At the time of installation I did not do the clutch spring (blue and white came with the kit) because I did not have a clutch holding tool.
The performance increase was nice - from 38mph to about 49 on the scoot speedo. I’ve just installed the:
Racing exhaust „Handmade ZX“
Art.-Nr. L4571
Again, without installing the little red springs that go inside the clutch because of lack of a tool. The perfomance „decrease“ was remarkable. Sloooooooow takeoff and sloooooow acceleration - roughly the same top end on a flat LONG road…but no torque to get it there going up any sort of incline.
I understand installing both the springs from the Exhaust as well as one of the springs of the Eco kit will rectify this and get my scoot about where I want it to be.
The 1st question: The eco kit came with a white and a blue tension spring. The installation guide indicates the white spring will increase it by 7%, the blue one by 15% → as I’m likely to have to pay to get these springs installed…I would like to do it just once, so I am looking for the best advice on which spring to use???
Last question… I do not understand what a „gear up“ kit is/does and whether I would really benefit from one on my setup?
I have no intention of messing with the carb (unless you folks think it’s required), neither do I intend to do a 70cc kit. What I was after when I started was just to increase the speed to around 50mph tops with a nice takeoff speed and good acceleration with sufficient torque to not suffer going up moderate hills.
All help/suggestions are appreciated! Thanks in advance.
Ben
