Had been riding for a couple of hours, not too hot outside, at one point I gunned it out of a turn in 3rd gear, all of sudden the engine light comes on. There was no power, just able to rev, dropped in 2nd gear, was the same. Finally put in 1st gear, it was only able to ride at 1500 RPM. I pulled over, turn the bike off completely. Waited about 2 minutes, then started bike no problem and continued on with no issues except engine light remained on about another 15km. Wondering if anyone has any idea as what it could be.
