2002 Triumph Trophy1200

Welcome to the forum Rob.
You're not using that new'Buckaroo' Australian petrol are you ? lol
It's either your ignition timing that is slightly out or your carburation.
A good clean out of the carbs would be my first task.

 

Hi Rob, you're not trying to run too slow in to high a gear are you? At what revs do you normally change gear when you're going up the 'box 12,3,4, etc

 

Is the choke coming off fully ?

 

Blocked air filter?

 

Sounds like the crank position sensor is failing. If the bike runs ok when cool but starts to play up when hot and then runs ok again again when left to cool down somewhat, then it will almost certainly be the cps. This is not an unknown fault apparently.

 

Hi and welcome - agree with Steve

 

You could try looking for ignition sensor ........ part no 5 on the drawing ......

BUT ... don't pay their prices. Have a look at www.triumphparts.gbr.cc where they are MUCH cheaper. Also check out www.squaredeals-ltd.co.uk as an alternative source of bits 'n' bobs - although not, it would seem - crank position sensors! Or did I miss them??

 

isnt it in the clutch casing?

 

Small black wire exiting clutch cover at about 1 o'clock position (ish!), then running back behind the breather pipe toward the air filter box.
Don't know of a specific test to check its health, but I guess that checking the connections etc wouldn't hurt.

 

Never had to do it on mine (kiss of death there!) but it seems probably more fiddly than difficult. But you need to leave an air gap between the rotor and the pick up itself - according to Mr Haynes Book of Fairy Tales that should be 0.6 to 0.8 mm - it says here!

 

so you need feeler gauges

 

Wouldn't have helped. Cheap fix if that is the case - and one for my memory banks!
