Engine cranks but only backfires, no start

Had the dealer put a bore scope down it and according to the tech he said the nikasil coating is basically gone where the scoring occurred. So being typical me I took it to my trusted tech who has much cheaper hourly rates to see what he comes up with now that he isn't busy fixing 4 wheelers... He had a hard time believing that the nikasil coating could be compromised with how hard it is

Well if that’s what he saw that sucks! Sorry for your troubles. Never would have thought that either.
