8V idle should be a bit higher, 1250 +/- 50. Nobody has buggered about with the throttle stop screw have they? It has been tuned correctly?

hmm reading the idle speed from the dashand maybe reading it wrong as its in 250rpm segments i will check with actual speed with guzzidiag to be sure, no the throttle stop hasn't been touched. It was tuned after being recently rollerised. Will take a good look at everything tomorrow. Thanks for all the advice and help. Its the last little niggle about this bike to sort...at the moment anyway !!

Did you confirm your valve clearances were 0.1 & 0.15mm (4 & 6 thou)?

Ok problem solved! Had time to lift the tank today to inspect the stepper and look what i found!!!

Looks like the previous owner had fitted what i believe to be a stepper shut off valve?? For some unknown reason this was hidden out of reach under the tank ....Why..??? who knows??? Maybe to try and solve a problem he had?? I did have to replace the throttle position sensor weeks into owning so maybe he thought he had a problem with the stepper. As soon as i removed the extra plumbing and tap and started the bike, idle rpm rose to about 1400rpm then gradually came down to around 1200 rpm. cheers
The plastic tap had a very small aperture and had collected a little oil so i guess this was restricting air flow, also the pipe looked a little kinked the way it had been fitted. I had lifted the tank before months back and didnt really notice this extra plumbing, which is now in the bin! So I then balanced the throttle bodies, reset tps and trims and all seems great. Lets see what happens when its cold, but im confident this is now sorted! Thanks to everyone for their input in this thread the bike is now niggle free!!!! just in time for some sunshine too!
