Boggy 400 ex?

Hey, I need help with my quad. My quad ran great all summer in the dunes, but Labor day it started running like crap. When I first start riding, it runs great, and has loads of power top and low end. After about 15 min of hard riding, it start bogging in the top end of the gears, and is a dog. I tore apart my block, replacing all of the gaskets top to bottom. Everything looks good inside, jugs, piston, crank, top end, and all the gaskets are brand new like I said. I'm wondering if it's an overheating problem....what do you think????

Thanks for the help...

I replaced the sparkplug boot, to make sure it's getting a better conection but nothing. I wonder if it could be in the aftermarket rev box, cdi, or something like that. Wouldn't that effect the way it runs right off the start though? It only seems to act up after some hard riding....

Thanks for the help.

Check Your Coil Sound Like It Is Bad. U Can Ride Untill Your Quad Gets Hot Then It Losses Power From What U Were Saying Rode 15 Min.then It Loss Power.it Start's Here Once The Coil Goes Out All The Way Your Quad Will Get Hot And Die. So Check Your Coil.

Well See U Later.

      Hi ya'll. I just got a 04 Kodiak 400 and Im confused.The left rear wheel moves like the bearing is shot so I figured its a quick fix. Much to my dismay when I looked at it before I tore into it ,it appears to have a drum brake-no bearing on the wheel. As this is the first time Id be working on a 4 wheeler job Im a bit hesitant. The manual only shows this has disk brakes.Its a sealed drum right behind the wheel.I pulled the wheel of expecting to find a bearing.Nope! Ive never done it before but it appears Ill have to pull the axle out to replace the bearing. Am I correct and if I am can anyone give me some advice on how to do it.The repair manual isn't much help. Thanks alot!

      I have a 2003 LTZ 400 that i bought a few days ago. The quad was running fine until last night. I let my brother ride it down the street and back and i didnt notice anything etong with bike. Then my neighbors friend came over and said "can i ride it?" I said "sure" so he ripped it down the road all fine and when he got back it died right in front of us. My brother said it was dieing on him also. He also said that he wasnt using the clutch to shift. I told him he was an idiot. Im throwing that in there incase that caused a problem as well. But today i go to check it to make sure its getting fuel which it is and replaced the spark plug incase it wasnt getting spark but it is. So i started it and it was having a problem starting then i got started and was reving at idle high. So i took it around the block and it died on me a little bit down, so i try to restart it and it started so i kicked it into 1st and it kinda launched on me and started going with the clutch all the way in. Then it died right after and wasnt running right during that process and was idleing all over the place and just died and now i cant get it started it again. Before it would start without the choke or priming it. It would start real quick now i cant figure if it needs to be rejetted or something else. Air filter looks clean also. But any help would be gratelly appreciated!
