Help 1980 XS650 Special II
This has been a long project. The bike starts and idals ok but stumbles and backfires when throttle is increased.
Recently replaced stator,battery, coils, wires, plugs, regulator, fuze box, and brushes.
Bike was running well.Drove it on a 400 mile (5.5 hour ride in 80 degree heat) Engine got real hot in traffic. Half thru trip the engine started backfireing on acceleration and stumbling. Also noted loss ofpower when signal was turned on.
Came home from trip and replaced plugs and inline gas filter. Bike ran ok for 20 min and started again. Took of carbs and looked for dirt. cleaned carbs and reassmeled. Bike is still doing. Looked at the forum and two things looked simular. Blocked jets and advance rod sticking. Not sure where the advance rod is. Dont know what else to check in carbs. Need help Thanks.
