I just replaced the cam chain in my 2000 400EX. After reassembling, the quad started right up and ran good. The only thing I noticed was oil burning off the exhaust (where it meets the cylinder). I thought it was just burning off oil that was spilled when I had the head cover off, but realized that oil was leaking internally (clutch side exhaust only). I took apart the head cover again and reassembled with a different gasket, but the problem continues. I can see that it is leaking oil internally, as there is smoke coming out the exhaust.
I did not remove the cylinder or take apart the valves when I replaced the cam chain. I also confirmed that my cam gear marks were in the correct locations. Compression test results are the same as before I replaced the chain (122 psi). The engine runs smooth, so I don’t think that the valve timing is off. Has anyone ever seen this before or do you have any ideas as to how I can further troubleshoot? Thanks!
I went out to take a 5y/o a ride, we get on the seat, I hit the starter and it started, then died, hit the starter again and it backfired and I heard a snap……..
so now when I press the starter it just spins and doesn’t engage, pull started it so the 5y/o didn’t have a meltdown and took him for a ride.
so is there some piece that breaks on the starter when they snort like that or did I twist something off?
Its a 1999 500 sportsman – thanks in advance, Robert
I know its brakes but its also a performance modification so sorry if im in the wrong section. I already got them on the back and im about to put them on the front. Wondering if anyone has done this before on here. I have 450 spindles, rotors and calipers. Trying to find out if there are any hidden pitfalls in this project that I am unaware of.
Hi, i have a 2009 outlander, when i turn on the ignition switch, the check engine light comes on and the machine wont turn over. If I am quick about it and turn the key and then press the start button before the check engine light comes on the bike will start. Any ideas as to why this is happening and how to fix it?

History:
Purchased 4 years ago from some kid who put a snorkel and after market exhaust on it.
Worked fine until this year.
Used primarily at low speed and RPM towing but sometimes I take it for a leisure ride and hit the upper gears.
Behavior:
Bike sputters out and dies in forward gear as soon as I give it gas but idles okay. This does not occur in reverse or when I rev in neutral.
If I gun it, it’ll sputter and backfire but keeps going.
With the rear end propped up so the back wheels spin freely, the problem does not occur. Seems to need a work load to trigger the effect. Applying brakes do not provide enough workload to cause trouble.
No indicators lit on the instrument cluster.
What I’ve tried:
Air filter clean
Plug clean
In-gear start safety switch fully disengaged and seems to be working correctly.
Fresh gas.
Oil clean and at correct level.
I changed the plug and it ran great for 30 seconds before exhibiting the same behavior but not as severe. It seems a well used plug exacerbates the problem. This leads me to believe there is a problem with the ignition system caused by a malfunction of one of the safety features that become enabled when in a forward gear.
This is my first time ever messing with the tuning myself and I was curious what the tune should be close to for a full HMF and Rev X? Thank you for and help in advance.

What do you guys think, is it worth putting a plow on this machine? I’m in Massachusetts, so we do get a fair amount of snow. If I do it, I’m guessing the smaller the better blade? Has anyone done this? What about a craftsman garden tractor blade? Any thoughts would help
