After installing the PCV-Autotune on the Griso it gradually began runnung a lot richer, to the extend where you could see black smoke at idle and it also started pinging. After having the rich running part rectified ( that's another story, thanks Mike.C) i am left with the motor pinging, and would like to work at solving this problem.
Two topic posts i have read recently gave me two starting points to work from,
1. The use of 10-60 oil instead of the 10-40 i am using now.
2. Carbon build up on the pistons and valves, which i am sure would be the case since the motor has run way rich for 12 months.
The oil part i have sorted but can anyone suggest the best safest way to decarbon the inards ?
