I'm not sure but I believe he has. I don't think he has any 250r specific intakes complete, which is why I used his 450r G3 model as he mentioned Dan Hung had done something similar with his no-link
BTW I gave this thing a test ride yesterday. Initially I didn't make any jetting changes, but didn't even complete one lap on my little test XC track before I started hearing some pinging. Went up two full sizes on the main, 1 clip richer on the needle, and one size up on the pilot. The huge filter and increased airflow really wants more fuel
