I went out fo a short 10 mile ride crested over a little hump in the road going just quick enough to take the weight off the front tire. Maybe 70 in top gear and she just died like you hit the kill switch or something she started right up but it just seemed odd. I usually hit the hump at 100 in 3rd and pack the front wheel alittle ways. I have bit of fear when it comes to purposely trying to tear up my bike, tires, a$$ ect.especially my a$$.
