I don't want to get into a debate whether the purchase was worth it or not, but for those of you who already have it, I can't get the diaphragm rod through the hole in the powerbowl. The hole is too small. Being Sunday, I don't think tech support will be around. Anyone had this problem? I was looking forward to getting the bike up and running again today. I am considering just drilling it out, but..... It's a 2003 YZ450F w/zipty mod if it helps. Thanks, Dan *EDIT - figured it out, it was just some kind of wax or varnish build up in the hole. all is well.
