i have seen advertizments about ceramic coatings on pistons, pipes, heads, and cylinders are they worth it and do they work swaintech.com does this work and they say you can jet down because of the coating
While it's true you can jet down some with coatings, it really is not the way to go for that reason. Ceramic coatings reflect heat and prevent minor detonation from causing a meltdown. But only for so long. If you have a detonation problem on th trail due to bad gas, it will help you get home w/o meltdown. Every body is trying to squeek more out of their Doo by jetting down. Doos don't like to run lean like the Po. They like rich. They run stronger rich with the timing on the edge. The problem with the big twins is they are already having trouble dissapating the heat generated by combustion. The heat is pushed to the rings which in turn seem to want to burn up. Jetting to the lean side can only worsen this problem. I recommend that if you want some cheap insurance from 'bad gas' detonation or a late night subzero return to camp, then get coated. Don't coat to jet down.
