I'm wondering if I need to balance the throttle bodies on my 8v Griso.I have a new symptom, which has occurred quite suddenly, and I'm struggling to imagine what may have happened to cause it.The bike fires up fine, but after pulling away, is a bit sluggish. With a bit more throttle everything kicks in, and she lifts up her skirts and goes, in the usual familiar way. It feels a bit like one cylinder is taking a bit longer than the other to join in with the fun. It's not missing - I know from bitter experience what it feels like with a misfire on one side, and this isn't it.Can the throttles go out of balance in the normal course of events?
Are you running a Beetle map? That will help with that low 2-3K RPM flat spot. Doing the throttle bodies cleans it up almost entirely...probably could do it completely if one super fine tunes it.I will say however, that while both of those massively improved my Griso's response at low RPM's, there is still an ever so slight miss, but I just power thru it...however the above 2 items made a huge positive difference.Sounds like the same issue...mine is a 2015 8V...not sure what your model is.
Throttle bodies typically get out of balance over a period of time. If this change was sudden, then there may be another cause. Not saying you shouldn't balance them. They should be balanced periodically. When you got it rollerised, they should have put the latest factory map in. The very first 8V maps were horrific. As a first step, balance the TB's, then use GuzziDiag to reset the autolearning parameters.
I've got manometers. And I had Guzzidiag, but that was back in the lovely old days when I had nothing to do with Windoze, and everything was Linux based. Sadly updating my hardware means I am again a victim of Windoze 10. So I suppose I need to download it and start again.
You do know there's Linux flavours of GuzziDiag?
I'm windoze now
