Got my GRiSO back from its first service and it runs much better. One issue I had was the pressurized gas tank, lots of air whooshing out when the cap was opened, several times it included a spray of gas. The mech found a pinched tube the second time he looked. They also gave it the 2230G802 map and balanced the intakes + a TPS reset and all the other stuff. It no longer surges and hesitates between 3,000 and 4,000 RPMs, I can feel a very slight dip at 2,500 but its minimal. Very nice to ride around town now, it was torture before!
The only thing they couldn't fix was the speedo sensor, when it comes in they will take care of it.
I normally approach dealers with great trepidation, but I am finding that Pro Italia in Glendale, CA has been super. All promises kept so far...
