I had my first experience with this today.
The situation was,..
Only about 1 gallon of gas left in the tank. Took 3.95 gal at the fill up, less then 3 miles down the road.
Petcock still on the main
, the low fuel light came on right after this happened.
I had stopped on a slight incline...maybe 15 degrees, needed the brake to stay put.
Made a right hand turn onto the highway, with alot of lean on the bike(no boards dragging).
I was rolling on the throttle good coming out of the lean, and had good revs in gears 1 thru 3 with no issues, when I slipped it into fourth, was when I noticed the miss. I didn't hit the rev
limiter in 1 thru 3. Maybe 3800 tops.
I figure between the slope at the stop sign, and the wait for traffic, combined with the low fuel. Not being on reserve yet. The right hand turn, and goosing the throttle good, I managed to starve her for fuel. No issues after switching to reserve. I don't know if the pump would have prevented this or not
Anyway, I know this is a concern for some who are pondering the mod, and this is the first time I've had an issue in 500(edit, 733 at the fill) miles.
