Well I got a little disappointed when I opened the Polini variator kit. The varator seems to be correct, but the belt is way too short. The spring looks like it is correct as well. Got some other parts aso, and I will come back to that later.
What do you think of this engine? Should I buy it and put it in the 50 chassis? The only fault is that the kick is weldet to the shaft. (This according to the owner)
I did "modded" my new airbox today. I just opened the inlet from 17mm to 21mm. I don't know if this will gain so much power, but it "feels" real good to have done it.
Here is a picture that shows what I have removed from the 1 halfe motor casting. More to come....
