Kyle, IF I even slightly suggest a Rotax is not PERFECT, I get Howled down Mercilessly, no matter what facts I bring up. Most of us who have experience KNOW that NO machine is Perfect. I was Pretty good Mates with Bert Flood some time ago and he didn't say they were Fault free.
I've been building, reconditioning Balancing and Modifying engines all my life Pretty successfully If I may say so judging on Performance and lack of failures Your work is quality and well based. Keep up the good work. Nev
