Need some help i have a 2001 400ex that smokes on start up and smokes even more when you give it throttle. I just noticed that it leaks oil at the header and motor connect. I just got it from a guy that said he rebuilt the top half and he told me that the valves needed to be adjusted. But what will make it leak? Thanks in advance

I am about at my wits end. Took the 250 back to the dealer repair shop AGAIN. Had it in there two months ago for a bad smoking issue. I thought it was to much fuel and washing the oil off the cylinder and burning it. They said it was the head. So I purchased new valves, valve guides, oil seals and had the head professionally done. So $225 later I had a great looking head. Well while I had the ATV apart this far I also got new rings for the piston. Mic'd everything out and everything was in spec. Put it back together and seemed like it smoked a little at the house (5000 feet above sea level). Took it to the mountains (9000 feet above seal level) for Sept. bear hunting and couldn't use it. Smoked worse than before and couldn't run it past half throttle or it would flood itself out. So brought it back home and it is back at the shop again. I say it is something in the carb that isn't set right or wrong jet????????? Anyone have any other ideas that it could be?

I have a 2000 LT250 that I recently had to replace the key switch due to the loss of the original keys. Now I can see smoke coming from in front of the gas tank. I took the cover off from around the handlebars trying to see where it was coming from. I touched a small box that was so hot it actually burned my fingers. I disconnected the battery but I can't get to the box without taking off the rack and the front fender. My owners manual does not tell my what this is. It has 5 wires running to it (3 yellow, 1 brown & white and 1 red) it appears to be bolted to the frame in front of the gas tank just below the handlebars with 2 bolts. Can anyone help me with this? I added a couple of photos to show the item I"m talking about. Thanks in advance.

just got my motor back together and its still smoking not as bad as before but smoking pretty good still, the motor had a bad valve and one of the head bolt seals where bad and was dumping oil into cylinder so there's a lot of oil in the tailpipe cause the guy I bought it from ran it around his farm and didn't care about the smoke just bought a new plug when it fouled, could the smoke im seeing just be it burning off what's in the pipe? Bike doesn't smoke to bad when idling just when giving it gas? bike has new rings, new valves, new top end seals, new aftermarket trx carb bout an hour break in idling in my yard, the head shop said one valve seat was in spec but barely could that be the problem? any suggestions are greatly appreciated

I have got a 87 big bear 350 4x4, I have been working on.It was running rough when I bought it.I cleaned the carbs and need to adjust it a little more to get it right,but it is running better. But, the problem I have it smokes alot,when I bought it and got it home it was low on oil and did not smoke much,but after I added the proper amount of oil it smokes alot.It is white colored smoke and it has oil residue on the tail pipe,it seems to have good compression. Do I need new rings or valve seals or guides? Any help would be appreciated.

First off im new here so hello to everybody, second a friend of mine has a 2000 400 ex that i am thinking about getting, and it was smoking really bad so we tore it down and the cylinder looked fine but the exhaust valv:huh:e had about a 1/8 inch of something that looked like carbon buildup but was white on it, could this be from burning oil , do u think it needs valve seats or seals or maybe just a set of rings, it runs fine just smokes and uses about a quart of oil in 8 hrs, thanks guys
