I had similar cut off issues when hitting bigger bumps (m900). it turns out the battery was too tall and its positive was hitting the underside of the tank, blowing the main fuse. new fuse & it fired right up & ran just fine.
Ride the bike to work two days last week. Day one, hit two bumps and the engine quit and was able to pull off freeway. Lights were on. Shut bike off and then on and it restarted. Figured my foot hit the gear shifter (was in 6th @ 60+ mph) and that is what caused the engine to quit. Had a similar experience with my Harley.
Day two, hit the same bumps again and nade sure foot was not under the gear shifter...engine died again.
Concern was rose considerably as now the LED head- & tailights both blew their fuses. Looked for bare/broken wires and did not find any.
Rode home with no lights. The bike surged, going 60+ then felt like it was dying and then back to speed.
Looked over bike on weekend, no broken wires and grounds were tight.
LED lights still blow fuses and tail smelled like it was burnt.
OEM head- & tailight work after new fuses installed.
Ran bike for ~ 30 miles and all seemed ok. No surges. Ran it Sunday night and close to home it surged again before the engine died 2 blocks from home.
What problems do I have (will be looking at over weekend again)? Seems electrical to me...maybe regularator/rectifier? Looking for solutions. Thanks.
