Decades of restoring old bikes to new/near new has created some bad habits that still remain, or maybe I've just always been a bit anal about things. I still collect likely to fail and consumable parts after I buy a bike...bulbs, gaskets and seals, plugs, filters, rebuild kits at first, then items I have had to replace during restorations in the past. Got a lot of ST ideas from reading about maintenance issues from this site...thanks guys....which helped immensely when I refurbished our 1991.
Since we are discussing fuel system here, I'll focus on that. I followed Uncle Phil's advice on aftermarket fuel pumps and submersible hoses and found spares. While looking for these, I found a new fuel pump assembly on Ebay someone was selling (buy it now price) for way under half the retail....and jumped right on it. Long story a bit longer....ST1100's (and ST1300's) are all old bikes now so unpleasant surprises will be on the increase with time and mileage. If you can afford the space and money, build up an 'emergency' stock of your own.....if you intend to keep them a bit. There's always a market for left over spares after you pass a bike on.....even Cushman, which surprised the heck out of me.
