My young blokes 2008 Fatbob has been parked up approx 6 months has always had starting issues.. recently replaced starter clutch in starter and haven't been able to get her running.. 

starter motor condition . ie armature bush's,are they worm ,allowing the motor to pole and draw excessive current,will be similar to a battery" loosing charge" while cranking ?

Cheers Bruce.. do you mean the bushes in the solenoid..

not in the solenoid [ no bushes in there ] ..the bush's/bearings in the starter body that support the armature shaft.

Ok..gotcha so what am I looking for exactly there? Obvious wear?

ok,i'll take a step back,the armature is supported by roller bearings [ not bushes] so i'd be surpised if they have given out [ unless it has done an extreme amount of cranking over time ]but if they have failed[ one or both] there would be radial [ side ] movement of the armature,the starter wil need to be dismantled to check this........but before going there,i would suggest carrying out a starter amp draw test and the best/quickest way to do this is with an induction amp meter,no dismantling to do....just access to the starter positve lead and crank for a short time with the plug leads disconnected. for an '07 dyna the draw should be 180-200 amps while cranking, i'd imagine an '08 would be the same.....but before all that make sure all lead connections are clean and secure,positve and negative.i may be way off the mark,but time will tell i suppose.good luck in the search.another alternative is try a substitute starter...the one that every one has in their back pocket...lol.

Hahaha yeah just happen to have one in my sock drawer 😆

i'm a JD tech and most days its the appropriate spanner in one hand and a lap top in the other......when i started on tractors [ grey fergies ] they only had 2 metres of wire... today its 50 metres or more,does ones head in at times. old is good.

Mate works on Learjets. Nearly 9km of wiring and around $18,000 just for the harness alone. That's alot of tubing just to carry around some smoke.

bugger that..i get lost just looking in the cab.

Gotta LOVE that MilSpec aircraft cabling though!  I run it on the FXR and its a dream to use.
