Three years after first getting my GS (1100) it's stopped working as well as it used too and despite trawling this site for potential fixes I'm all out of (affordable) ideas and my budget to fix it seems only to get smaller.
My problem started last year when out on a short run my bike started to lose power after about ten miles, I continued after topping up with petrol but by the time I'd done 20 miles the power was right down. I was visiting friends and was there for a couple of hours before completing the return journey which pretty much went the same way, from cold it was ok but after having completed the 20 miles home I could barely pull away from the lights.
I've tried many things and on occassions it's seemed better but it ain't right!
I've changed the TPS (brand new), tried a different coil, HT leads, ECU (second hand and untested) and plugs (brand new-also untested!!), I've checked the tappets (OK), compression (7 bar rising to 8, same on both cyls) and throttle balance (OK when cold but a slight difference-about 1/2 inch-when hot), the injectors look OK but when cranked doesn't give a fine spray (?), the throttle cable is seated but does run real badly on the frequent occasions I forget to put it back correctly, also checked the fuel ( no water) and fuel filter (new fitted), the coating/paint on the inside of the tank was breaking up and peeling away so I removed all that was loose and cleaned up the gauze fuel pick up, there was a problem with the off-side injector wiring, but I've replaced that by grafting on a new section, I've even changed all the relays.
For those who have got this far, thanks, I would of given up before the end of the first paragraph. I'd be grateful for any further advice, especially if it gets my bike going again.
If theres not much in the way of things to check, suggestions as to who to take it to somewhere not to distant from Aylesbury, (that's in Bucks) would be a great help.
