Default 450 FSE 2004 starting issues

Hi all,

I spent time stripping and cleaning the callipers, new seals, pads etc... Changing the bars, tyres and just getting it ready to ride.

As a matter of course I carried out a compression test it was just above 100psi, further investigation revealed it had suffered a dropped valve and they had left the piston in. The barrel looked like it had been sandpapered and the rod had about 2mm vertical movement on the pin (it had worn through the case hardening).

I've spent circa ?800 on new rod, piston, nikasil bore, gaskets, bearings etc.

I have a good spark and after checking the injector - what looks to be a good fan spray. I have now the diagnostic lead and have re-set the tps. The CO trim is see to 0. The sensors all appear to be reading correctly (guzzidiag)

The fuel is new and so is the plug. I have 2 relays on order and my next steps are to check the value clearances again.

Chris.
