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!
my 955i speed triple will not over it just clics under the seat new battery just fitted and all electrics work
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.
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!
I had removed all fasteners save one. This allowed the part to dangle and make contact near the collector.
