Not personally but we have riders adn delaers at those elevations that we work close with. 99% of or atv products are intended for consumer use which in most case the exhaust, heads, porting stuff along thosae line don't need to change like they do on race engines or hard to tune products for elevation changes we normally only need to change jetting and clutching.
