There you go....... K&N filter makes it LEAN as hell. Yoshi pipe makes it even more LEAN. If the jets are stock, I bet it runs like crap. Most people don't have the patience to get the carbs tuned to the K&N filter and end up going back to stock. Check all the hoses on the airbox & carbs too. I've heard about someone else have similar issues because a hose was off.
Another guy had one of his slides separate from the diaphragm, in 1 of his carbs, making the bike fall on its face around 8-9k, check those too.
