Hello again all, i decided to start a new thread but will refer to my previous thread (on the same page as this) because it has all of what Ive tried up to now.
I'm am getting very high co unburnt fuel readings, smells so rich too on tick-over, lumpy to pull away, black around the exhausts and plugs black but firing good.
A friend asked me if it has a two stage injection system, i do not know this.
Ive come to a brick wall, would really appreciate some fresh ideas.
Thanks. Dave
 
A power commanda has been suggested but I'd rather find out what the problem is, rather than patching it with an after market product and spending an extra few hundred pounds on it, after all suzuki spend millions of pounds developing these bikes to run smooth with low 'ish' emissions.
Could a faulty throttle position sensor cause over fueling?
Dave.
