Motor is definitely spinning fast, but got a new top speed today:
Setup: 70cc Athena reed kit, 19 mm phbg, estoril (no mods)
what gps is that? is it cheap?
Not gps, digital bike speedo. Uses a magnet pickup on spoke and you input the circumference of the wheel. Verified against radar at 45mph.
Thats quite good for that particular setup if its unported. That kit has potential to go faster, but it takes a fair bit of grinding to do so.
The only mods to the kit itself were to the piston, cut a large window on the intake side skirt.
Also has a high compression head, and a dmp stuffed crank.
Gearing is 18x45
