I just bought this bayou 300 for a great deal. The guy that I bought it from said that the gas tank rusted and he had been having problems ever since. I cleand the jets in the carb, changed the plug. It sounds like it it trying to start and the it backfires. What else is there to do in this situation?

He said the gas tank rusted? It has a plastic tank!

-It sounds like your valves need to be adjusted.

It had a metal tank I suppose, and he replaced it with a plastic one. How do you adjust the valves?

Those machines didnt come with metal tanks. The only way it could have had one, was if he made one by hand out of sheet steel.

You will need to get a service manual to adjust the valves. I dont have the time to describe how to do it.

Check the timing

The exhaust, I know nothing about these things I'm learning as I go, how do you check the timing.

Mike I would make a suggestion that you find a friend a friend of a friend that knows about these kinds of mechanical things. you are in dangerous territory and could realy scerw something up, ends up costing you a ton when it should have cost you $.50 Get a manual for the bike study it!
Good Luck

Just get a manual and check the valve lash. Unless you tore apart the top end the timing should not have changed(Unless the chain tensioner broke). Start with the easy things first, before jumping to conclusions.

what year is you bike because mine does this and i have torn the **** thing right down to the frame many times and nothing i do seems to work but, sounds like it is flooding which mine does and then it will back fire i was trying to get mine running yesterday and i has backfired before but jesus i think it must have goot about 5/6 times the amount of fuel it should have and i couldn't here any thing for a couple of mins lol. but try taking out your plug and you will probably find is is fouled by oil if it is just clean the contacts with some fine sand paper and then put some fuel on the end of the plug then stick it back in with no choke you will probably find it will fire then leave it for a few seconds then introduce some throttle and i mean the tiniest amount then if it startes to bog let off then when it clears blip the trottle and if it hasn't died then pin it for a couple of seconds then get on it and rag it found for a while (this is just how mine starts it may not work for you but good luck) oh just one thing dont be scared of it backfiring it wont hurt you lol

Sounds Like You Have Got Your Bike All Figured Out I Really Hope That I Don't Have To Do That Every Time. I'll Give It A Try, Thanks

If you are still dealing with a simple no start and backfiring issue, go get the repair manual and follow the diagnostics listed therein. You need to start down a deliberative path and rule out each potential problem area or you will be shotgunning this forever. Raccoon management, grasping at every idea that flies by, does not work to diagnose and correct engine problems.
