Accelerates fine, stalled at 35 mph today, started after 2 minutes, Tried to tighten batt cables, still no good, Triumph claims VIN not recalled, PS also Can smell fuel odor and sulfur smell . Started about 2000 miles ago, used different gas and gas additives.Any ideas? Thanks.

First of all, welcome to the forum.

Can you expand on "starts bucking while crusing at all speeds"

If that's on a constant throttle setting, when it otherwise behaves fine when accelerating, then that sounds like your primary tps is out of whack or just knackered.
 
Welcome! any dodgy idle probs?like when stopped at a junction? ( that's TPS)
Otherwise, mebbe check the sparks. Coils mebbe?
 
Could be way off the mark but the smell of Sulpher is usually a dry or arking battery cooking itself.

At normal/consistant speed the dead battery might be burning off all your power and the alternator can't supply enough power to the ECU to function properly.
When you accelerate you get extra power and it runs ok.

Like I said, I could be way off the mark but that's where I'd start.

Ive had a sulpher smell inside my landcruser for the last day or so.After reading that I went and checked the batteries and the aux battery is so hot it is painful to touch.
Last week, the temp warning signal/gauge ,which is plugged into the aux battery,started playing up by going off with a cold engine.
Plugged it into the main battery and its ok.

Sorry for the hijack
 
Thank you all. Idles ok, but when increasing RPM's , with no load, There is definite missing, not smooth at all. Thank you.

Yes, when crusing at 55MPH, or any speed when not accelerating, the bike cuts in/out like a loose plug wire, loose batt connection. As soon as I open the throttle, she accelerates fine. It gets so bad,You want both hands on the handle bar at all times! Thank you.
 


That really sounds like the primary tps is out of adjustment or completely shot to me - exactly the symptoms I've had (twice) when mine went.

Before you go fitting another one, though, you ought to check your vacuum tubes for leaks, and clean the crank sensor.

Whether this sympton has anything to do with the sulphurous/fuel smell is another matter entirely - that is outside of my experience.
