Engine missing is a vast subject and calls for number of things to examine. What are the problem symptoms? Is it concerned with one or more of the following?
- Rough idle, stalls or misses.
- Engine hesitates/ poor acceleration.
- Engine diesels (runs after ignition switch is turned off).
- Muffler explosion (after fire) on deceleration only.
- Engine backfires.
- Engine rattles at idle speed only.
- Engine rattles at all speeds.
Please mention if there is some other symptom.
Thanks.

So i've recently run into a problem where the bike


If it was a two cycle I'd say it was clogged exhaust ports. But you have a pretty exotic bike. So I guess it's a timing issue dealing with the exhaust Ox sensors.

94 chevy k5 blazer works fine cold problem is that when it worms up it stalls backfires into the exauhst and losses power and turns off


Most of the time if it was a fuel pump it wouldnt start at all.Sounds like a tps problem.If there is a check engine light on, it would probably be cheaper to pay someone to scan it, instead of guessing and buying
sensor after sensor.Some of them are quite expensive.
Hope i was of some help

Sudden loss of power, Backfiring, starts then stalls


Your timing belt could be broken. You want to have this checked as soon as possible to prevent any further engine problems.
