super tenere 750 missing/backfiring

[jaff]

got a 1994 super tenere 750. has been missing terribly/losing power going up hill. changed plugs 5 months ago, went fine, but slowly gets back to square one. backfires when coming down hill/change down a gear., and struggles to get up hills - and misses badly and basically sounds more like chitty bang bang than a bike!.just changed plugs again and checked air filters, and it's going well again. old(ish) plugs were black and sooty. changing the plugs and getting to air filters has been the pinnacle of my mechanical career so far, and any suggetsions on what the problem could be would be greatly appreciated!

I'd go for the good old carbs, whip them out strip a clean, refer to manual for setting up they might be running rich if all your plugs are black and sooty, if this doesnt seem to work try checking your HT leads for any damage could mean a new set if the plugs aren't being supplied the spark they need, last but not least it could even be the coil not putting out the spark in the first place.

A nice bit of sunday afternoon tinkering for you there.

Hi

Sounds like its running rich - so check and reset carbs as a first - also check timing as well.
