anyone experiencced any vibration due to top motor mount being defective? ATV is fine just not smooth as the 800
seems it"s in the top motor mount..it looks good but maybe it"s the bolt or the hardness of the bushing ..any info?

 

A few folks that I know have broken the lower mounts right off. The bolts sheered. This of course took the engine and tranny out with it. I replaced my lower mount bolts with grade 8 bolts, they were grade 5. I only replaced one of the upper bolts with class 10.5 (metric version of grade 8). The other bolt is behind the header.
