Just found this

yeah my reeds looked identical to that same crack etc. it started and just bogged for like 30 15 and wouldnt start
 
it was a pain to start sometimes. But get her wound up and it would run good. I took it out today after replacing the reeds. Runs pretty good but I still have a tiny low end bog. I think I need to fatten the pilot up just a little. But the quad is badass!!
 
here, because thats classic.....

Would this cause a low end bog? The guy I got the quad from said the motor blew up and he found little pieces of "something" in the cylinder and then he rubuilt the motor. He never checked the reeds. I just pulled them out trying to figure out why no carb adjustment at all made a difference.
 
typical aftermarket dual stage failure !!!!!!!!!!!!!!
