2004 Suzuki Eiger Smokes & Runs Bad

[chevy9588]

My friend has a '04 400 eiger 4x4. he took it through the mud and it died. ever since it doesnt run very good and it smokes really bad. we drained all the fluids and filled them again. we did that a couple times cause it was still smokin. my thoughts are the piston wall is gouged out but i dont know. any ideas? also where can i find a good diagram of the motor in case we have to tear it down?

Do a compression test. That will tell you alot. Did you check your air filter? It could have just gotten really dirty. If you need to get into the motor, get a manual, it will have diagrams and specs that you need.

yeah we changed the air filter and the oil filter. i hadnt thounght of a compression test ill check that this weekend. can you get a manual at oriely's or other part store?

Probably have better luck finding a manual at a Suzuki dealer, you can probably find one on ebay too. Another thing you may want to check is the stator, you could have gotten some moisture and/or sediment in there.

Have you changed or looked at the spark plug?

Hello.

Was there much oil in the motor when you drained it out the first time?

Many Eigers when they are ran out of oil, scuff up the piston and alloy melts off the piston on to the cylinder wall, then killing the rings.

Then when you put more oil in to the oil rings dont work and the bike blows alot of smoke.

But normaly still runns ok for most people.

you did say that it was a muddy ride, so there is a chance that the oil cooler is covered in dryed mud and stopped air flow and thus the guy over heated the motor, and killed the piston/rings.

Did he get bogged and reved it like mad to get out and keept trying?

i just bought a used 03 eiger with no compression it had been run out of oil and the oil cooler fan fuse was blown make sure the fan works!!! or you will melt the piston you might get off cheap replacing the rings but rings and a piston are about 150 bucks
