Is mine tuned properly. Probably not but it’s pinked when it’s hot since the day I got it. I say ‘pinked’ because that is sort of what it sounds like: loud rattle mainly left side coming from the cylinder head manifold area but only when pulling away from standstill at about 2500 rpm. I did go round tightening stuff up thinking it was something loose but as it only does it at low revs in town I do think it’s pinking or related. Lots of reports of similar issues on the various V85TT Facebook groups I’m in, although the latest story there seems to be it’s not pinking but piston slap as the cylinders expand faster in heat. I call bollocks on that one. Above about 3k revs and it goes away anyway.
On the tuning front, I took it to J33 tuning for him to have a look - he’s local and does a great job on most bikes. Long story but he said it was too difficult/long winded, mainly as each change he made needed a TPS reset in order to clear the ensuing fault that the ECU detected. A tps reset took 20mins and as he had loads of changes to make (try out I think) the process would take days. Most of the time the bike runs absolutely fine so I’m not desperately bothered.
There’s also a more or less plug and play tuning solution developed by guzzitech in the US. You buy a “black box” that you plug into the diagnostic port on the bike. It downloads your bike’s software which you email off to guzzitech. They then send you an updated fuel map which you install via the “black box”. The black box also does the tps reset which it seems they recommend you do once a year anyway. It’s about £300 so I’m giving it some thought but need to read around it a bit more.
