High speed crap out
On a ride last week my Xs11 died for not reason... or I thought. Turned out that the recitfier went bad. The shop put in a new rectifer but now I have a differant problem.... At low speed the bike runs fine. Even winding it up tight, but when I get on the highway and punch it the moter sees to loose all power. basically it's running only on a couple of cylenderes. When I lket off the throttle a little it some times backfires. I live in southern Utah and it's hot but I don't think its a vapor lock issue. I was wondering if it could be a coil? Help please.

Sounds suspiciously like you have a bad pickupcoil wire. Under the left engine cover.

Thanks guys. I pulled on the wires of the pick up coil and there was no differance. It runs fine at our normal highway speed ... 55 - 60 mph. It's when I get it on the freeway where I need to punch it up to 75 - 80 mph. It will all of a sudden backfire if I let off on it even a little, then it acts like I fuel starved or something. Thought maybe even maybe the coils.SICKO!!

Might have a blocked gas tank cap vent... But usually the bike will die because it becomes vapor locked. You can check it by riding it with the cap open, go give it a wack on the freeway and see if it happens again. Otherwise the symptoms fit for broken puck-up wires...
Did you try flexing the wires under the cover while the bike was at idle?'79 XS11 F

As BA80 stated, you STILL have a bad pick-up wire under that left cover. Can't just pull on them quickly and call it good to go, have to use both hands so u can pull in inch incriments to see if plastic sheaving stretches like gum to find a break.Originally posted by WMarshy View Post81H Venturer1100 "The Bentley" (on steroids) 97 Yamaha YZ250(age reducer) 92 Honda ST1100 "Twisty"(touring rocket) Age is relative to the number of seconds counted 'airing' out an 85ft. table-top.Comment
