I took de oil filter out i connected direct tube i start de it didnt start

Never start a new built engine without turning it over a while to build oil pressure first. Then if there is no oil pressure you either have a bad pump, gauge, or possibly a clogged filter.

Check your fuel filter and change it if you havent changed it in a while

Sounds like a faulty fuel pump.Did you check that?

Your crankcase vents into the carb air filter. This was required by the EPA. All crankcase vented pressure has to be cycled through the engine. So, If you'll look behind your air filter to the rear of the bike, you should see a pipe coming from just behind the oil pump up to the backside of the air filter. The air pressure exhausted from the crankcase has an oil mist in it. There are baffles in the pipe but sometimes during servicing, these baffles get left out. Still, even with the baffles, there is some oil mist that makes it's way to the air filter. This oil builds up over time and causes a drip out of the air filter. Regular cleaning of the air filter assembly reduces this.

If you're getting more than the usual amount of oil, your engine could be "oil sumping". This is where the oil in the oil tank seeps past the check ball valve in the oil pump and builds up in the bottom end of the engine. When you start the engine, the oil pump cannot pump it back to the tank fast enough and it's blown out the crankcase vent tube right into your air filter. You can "reseat" the check ball and may be able to get it to stop doing this.

Or, you could remove the crankcase vent tube going up to the air filter. Put a piece of tubing about six inches long on the nipple coming out of the engine case and plug the hole in the backside of the air filter backing plate. Then, the oil will directed onto the ground instead of into your air filter.

Good Luck

Oh, one should make sure that the old rubber gasket didn't get stuck on the engine block where the filter is. Sometimes, people change their own oil and don't look at the old filter they took off, to see if the gasket came off and stuck to the engine block.

In that case, the new filter has a gasket, and the old gasket is stuck to the block, and you have two gaskets stuck together, which will leak.

This is a common mistake to happen on any car.

Good luck on this repair.

Check the oil level, if the fuel runs freely to the carb and runs out it may have filled your crank case with fuel. turning it over with less power than it needs will ruin the starter, battery cables and start relay. Anyhow, if crank case is flooded with fuel clean carb to remove trash,so the float can do its job.Change oil,and air filter,clean sparkplugs. OK if i took a wrong turn stay with me, check pistons for compression.If piston is cracked or the rings are bad or not set,pressure from the piston could escape into the crankcase and blow oil out anywhere.Good luck Mr.Schnot.

Check that the oil filter if firmly screwed onto the engine. If not then drain the oil, undo the oil filter. Wipe the surface of the oil filter connector on the engine so its clean. Get a new oil filter and smear a small amount of oil on the rubber seal. Screw the filter into place making sure it is a tight seal. Re-fill the engine with the right amount of oil. You should be good to go. Check that the oil leak is coming from the filter before you start as it could be something more serious eleswhere like the head.

change air filter, fuel filter, oil and oil filter, also if you have the money, get a smoke test done to see if you have an evap leak

if you never had that problem sounds like your oil is over ful and blowing thrugh your beather (crank case vent tubes) check and lower your oil level as needed and clean or replace air filter , should fix your problem
