    I'm new to the triumph 955i. In this case it's in my 2002 Sprint ST. The bike has been dormant for several years. After doing a valve check and putting it back together. It seems to spin over slow. The battery is new and charged. The battery passed a load test. While I have cleaned the harness ground. I have not checked the starter lead. Is there a known slow start or am I overlooking something obvious.

    Check the voltage at the starter vs the voltage at the + battery post while cranking the engine or put a multimeter (set to DC volts) across the + batt terminal and the + terminal on the starter motor to get the voltage drop. Less than 0.5 v is acceptable.

    I'm satisfied with the voltage to the starter. It spins over much like the Bonneville. The ST has moved to a no start. The three amigos air/fuel/spark are now under investigation. The fuel pump primes and builds pressure. The air is moving. I guess it is time to look closer to the ignition system. Not to mention the 250 plus safety switches....LOL!

    Update. I scanned for trouble codes and P0230/P1231 popped up. The wp 3 wire connector that is triangular had a severely damaged wire. It appears the injectors were not doing their part. I'm pretty sure this is a self-inflicted wound. Time to put it back together and get it a try.

    The damaged wire/connector is the throttle position sensor. The damage is on the harness side of the connection. It looks like rodents have made a meal. I would like to believe this was the only mouse meal. Experience suggests it is the first of many. Time will tell.

    It's a runner! Found two bare spots on the injector harness. The harness that I've looked at hundreds of times. Both spots near the connector that plugs into the idle adjustor thingy. I had a second injector harness. I see a test ride in my future.

    First impression of test riding the ST. I really like the 955i engine. The throttle is less than ideal. After some adjusting and lubing it seemed a little better. I like how it settled into a nice idle 1100 rpm. There is a lot to like about the ST. Mind you it was a short 5-mile ride.

    The ST is on its way to being buttoned up. Everything is working and several test rides later, all seems well. I even set the clock. Today I go out and fire it up. Cranks and starts without a hitch. The clock stopped working and the bulb in the fuel gauge expired. The old girl just wanted more attention, I guess. LOL

    If anyone enjoys trivia....I have a bit for you. Having accepted that the clock had left the building. I moved on to bringing the heated grips back from the dead. I managed to ground the heated grip switch and killed the 10amp fuse. Luckily while looking for a new fuse. I found a Miller Highlife in the fridge. I replaced the fuse and the grips now heat. Oh and the clock came back to life too. Triumph appears to have fused the clock and grips together. :neutral:

    Not sure how I manage to create extra work. Before I set off on a completed project. I Proform 20 or so start and function test. I like to see it repeat before using. I received the last couple of pieces of body work. I need to paint 4 panels before final assembly. Starting the ST and waiting for it to come up to temperature. I laid out the body work next to the bike. Missing the lower right bottom fairing/belly pan. I walked back in the garage in search. I noticed an odd odor coming from outside. I fitted the bodywork the day before to tweak everything. I failed to remove the missing part. It is now a melted mess of plastic. I quit for the day and enjoyed a couple Miller Highlife. Life is good!

    How come it melted if it was fitted in the right position?

    I had removed all fasteners save one. This allowed the part to dangle and make contact near the collector.
