Need a recommendation for service on a 300xs I'm buying. It's a 2012 and only has 110 hours, but I want to get the air and fuel injector system cleaned and up to par before I start running it. Have to assume some deposits and/or corrosion on the injectors from all the sitting, and spoke with one optimax injector cleaning specialist (back east) who said he's seen problems with the air injectors with as little as 20 or 30 hours. (I guess they can inject normal wear particles from the compressor or drive belt.) I've made a few calls, but no luck so far.....would really like to find Optimax specialist who knows the motors inside and out. Thx!
