I bought the Griso with a Staintune fitted and then soon after fitted the Lavizzari and then the PC-V and autotune.
I was happy with the improvements made by the PC-V but there were still some issues with jerky on/off throttle, a feeling of something just not right and recently the problem with the motor pinging.
On the weekend i changed back to the Staintune to see what difference it would make, and the changes were quite substantial.
The pinging has gone completely, no matter what i tried i could'nt bring it on.
The motor felt stronger and pulled better throughtout the rev range.
The jerky on/off throttle has smoothed out considerably. A lot more pleasant to ride at slower speeds.
It's a lot quieter and i have been able to pinpoint that annoying rattle as being the headlight.
The downside.
It's a lot quieter.
I don't like the look of the Staintune.
So for those who have been saying a more restrictive pipe works better, i agree :ugeek:
