Just thought I'd post a quick reminder to all of you 4T 250 and 300 owners! The air boot between the throttle body and the cylinder has a tendency to slip and pop off the cylinder inlet due to the back pressure created. I just checked ours again last night and it started to slip again. Its easy to fix (just loosen the hose clamp, slide the boot all the way on and tighten it again...and check it regularly! This is how we blew our 11 TXC 250 up last year...ran long enough with the air boot popped off to induce lots of dirt and destroy the head - $$$$
I thought I had a permanent fix for this with some safety wire, but apparently that did not work.
