  1. Good afternoon guys. I have an update. Lol. I finally broke down and took the quad to the shop. After rebuilding the carb myself, I was able to get it to fire up, but as soon as I hit the throttle more than a quarter way open, it stalled out. This was 8 weeks ago almost and it's still in the shop. Yes, can still. I'm about ready to give up on ol rumble bee. They had it for 3 weeks and rebuilt carb, checked valve, new fuel lines, new filter, cleaned air filter and called told me it was ready. Got it home and didn't make it half a mile and same crap. Back firing, hesitant, and never got into 4th great before it stalled out an acted out of gas. Gas dripping out the bowl of carb. And was like it almost had vapor lock. I had to remove gas house and allow fuel to free flow and get what air pockets out. Got it home and back she went. They had it for 3 more weeks and this time they have rebuilt the carb for second time, new fuel lines, bigger Jets, new accelerator pump, new cock valve in gas tank, check all the valve clearances, new stator, new rectifier, new air filter, new spark plug, new battery, and called to tell me it was ready again. Got up there and the damn thing will not idle and backfires still. Now she will run thru 3rd, limited space, and feels stronger than ever but will not idle and back fired almost every time you got on it. He is blaming the yoshimuri exhaust to be causing the back firing and he is rebuilding the carb again but this time using name brand high performance Jets so he said. Can anyone help, or suggest the back firing? My brother, which is a self proclaimed master mechanics of every engine made, said I needed to upsize me valve springs and to check compression? Hell idk I just want to ride man. Any help is appreciated.
  2. Man I've been searching, reading, YouTube, and a few other things for 3 days now. I knew the jet was somewhere because every kit came with it. It took me a few hours to figure out what people meant when they said leak jet. I really appreciate you taking the time out to help me and so polite and understanding with a newbie.
  3. I almost over looked the accelarator jet located in the float bowl top also. I had to take the thing back apart to actually find it. There is a million damn pieces to this little baby. I picked the wrong one to tackle being my first every rebuild.
  4. The one with the arrow is your main jet; #1 in illustration. The kit came with all jets needed. I've installed 5 of the 6. Just can't find pilot air jet.
  5. Can someone please tell me where the pilot air jet is located? I can't find anything other than on the pilot jet. It's on a 2005 yfz 450.
  6. What's going on party people? First, thank you for allowing me the opportunity to be here. I recently purchased a 2005 yrs 450 and have yet to run the bike at full throttle. The bike fires up, idles, seems like everything runs fine except a little popping when you let off the throttle or until you hit 5th gear. It runs strong; no bogging or sluggishness until you hit 4th gear and open it up. Then it begins to act like it's out of gas or the about to be out. I can pull over and sit for 5-10 min and it runs strong again until you open the throttle. I have the carb off the bike to clean and wrote down a list of factory and what I found installed. I also listed other key factors and hope someone can help and explain. I'm new to the scene and have no prior mechanical experience but my theory is worst case scenario I have to take it to the shop anyway so why not learn. I actually enjoy it. Lol. Thanks a million. Hope to get back on the trails soon.
