Hi This is a bit of a saga on my st 1100 pan, basically it runs ok but if I demand heavy acceleration on say an overtake there is hesitation at around 4-5k plus its almost like fuel starvation or possibly loosing a cylinder or something it fells like its holding back, but if I am gentle up through the speed range it appears fine.
I thought at first it was carbs so i managed to buy a complete set of secondhand carbs went through them and checked them out diaphragms jets etc all were good so I fitted them and took them to my local garage to balance up for me, all was fine there except it still had the same problem, it seems fine on the rev up off load when your on the stand. So my next thought was perhaps it was loosing a spark under load so I put new plugs still the same so I next put a secondhand set of coils just in case one was faulty under load but still the same. Now I am thinking that it may be a fuel feed problem and I am about to undertake stripping down the fuel system to check it all out but I thought I would bounce it off you guys to see if there are any of you out there that have had a similar problem or have any ideas as I am not sure what it could be.
Its spoiling my riding of what would otherwise be a fine bike, so over to you
Thanks
dave
