1997 Speed Triple Problems

Starting System Symptoms:

Weak battery symptoms:
-- Slow cranking.
-- Stops cranking suddenly on compression stroke with button pressed.
-- Starts when starter button is released at end of cranking.
Repair:
-- Charge/Test/Replace battery.
Failure Modes:
-- Loss of capacity. Appears to charge, voltage good but no reserve for starting.
-- Won't hold a charge.
-- Low voltage/cell failure.
Preventative Maintenance:
-- Check fluid levels regularly
-- Maintain full charge: Regular riding, trickle charger.

Ignition Coil failure symptoms:
-- Hard starting/misfiring during cranking.
-- Rough idle that can't be tuned out with carb adjustments and carb cleaning.
-- Idle misfire clears with new sparkplugs, returns in a few hundred miles
Repair:
-- Replace: Preferably with Nology for higher reliability than stock Gill coils.
Failure Mode:
-- Shorted turns in secondary resulting in weak spark.
Preventative Maintenance:
-- None
Testing:

Pickup Coil failure symptoms:
-- No spark at all
-- Spark quits with engine hot, returns when engine cool.
-- Note: Pickup coil failure is total. There is no random misfire spark loss.
Repair:
-- Replace pickup coil
Failure mode:
-- Thermal intermittant with long (15-30 minute) period.
Preventative Maintenance:
-- None. Get a spare.
Testing:
-- Ohms checks hot and cold.

Worn starter symptoms:
-- Sometimes won't crank until the bike is rocked in gear.
-- Excessively noisy cranking with a grinding sound.
-- Click from under seat but no cranking.
Failure Mode:
-- Brush wear progressing to commutator damage.
-- Bearing failure related to brush wear.
Repair:
-- Rebuild or replace.
Preventative Maintenance:
-- Maintan battery in peak condition.
-- Follow proper starting procedures. Neutral, clutch in.
-- Crank 5-10 seconds at a time max., switch off for twice as long before cranking again.

Worn sprag clutch symptoms:
-- Very loud rattling when cranking
-- Starter spins but engine doesn't turn
Falure Mode:
-- Breakage
Repair:
-- Replace sprag clutch
Preventative Maintenance:
-- Maintain battery in peak condition.
-- Follow proper starting procedures. Neutral, clutch in.

Worn starter solenoid:
-- Click from under seat but no cranking.
-- Won't crank after rocking bike.
-- Starter continues to run after bike starts and won't stop until the battery is disconnected.
Failure mode:
-- Internal contact damage resulting in non-conduction.
-- Internal contact damage resulting in contacts welding shut.
-- Internal damage/wear prevents solenoid core movement.
Preventative Maintenance:
-- None.
Repair:
-- Replace starter solenoid.
Testing:
-- For no cranking, short across solenoid high-power terminals. Normal operation denotes failed solenoidcontacts.

Fuel?

 

Then as smilinjack said, Crankshaft position sensor

 

If I were you I would see if your buddy can clear the fault list, as You have nothing to loose then retry starting after cycling the ignition off then back on.

A lot of those codes together look like a power disconnection with the ignition still switched on has chucked up a load of random stuff.

If you can clear them try a restart if still no joy, then re- read the codes see what you have.

 

Did the MIL light clear when the codes were erased ?

 

The sprag clutch generally gives trouble from using the starter with a battery that isn't fully charged, and I believe is very noisy in operation ( never had this problem so cant confirm ), also the sprag clutch is only used during starting so wouldn't have caused the engine to "quit".

I would suspect if the MIL stayed on then there are still uncleared codes & issues.

However it is possible that there are still error codes in the ECU that cant be read with a generic ( non specific ) code reader. So in your situation I would download a copy of TuneECU and the cable needed as the software is ECU specific and should show up any "hidden" codes.

 

Looking for help I'm rebuilding a 02 tt600 and want to go with larger pistons and crank but don't know what set I can use in the 600 casing I know I need to bore the head to fit the pistons but crank out of which other triumph I cld use anyone help

 

check valve clearances. poss they are negative on those engines.

Hi Ricardo

I would suggest that you start a new thread for your question as it will only cause confusion with answers to the OP's original issue. Especially as your motor is a 4 cyl and the OP's is a triple.
