I'm not fully into this guys deal. for a while now. I have no science to question it......but he talks about 1oz of 2 stroke oil per gallon increasing the Gas (fuel oil mix) to a higher viscosity that cannot pass through a 10 micron OEM Kato filter....I call some BS on that. So statements like that leave me skeptical of his stuff. Also KTM/Husky have legality issues for these machines in regards to EU spec these bikes are still street legal homologated for FIM enduro use......I have trouble believing that they are that close to piston seizure, the lawsuits will be enormous and the danger to a motorist with a seizure on the public road.....but then again the factory rebuild/maintenance chart can answer that, and it most likely says 20hrs and do a top end, its an enduro race machine. Any my words about the piston stuff are conjecture. About that mixture viscosity increase being anything other than super minute, I'm sticking with that.
