First of all....don't let your bike sit and idle for 5-8 minutes.  It is better to start up the bike, run it for about 30 seconds when you are sitting on the bike, then ride off gently for the first few miles.

At idle the bike has low oil pressure and is not pumping a good amount of oil around in the engine....and we are also beginning to form an opinion that while the bike is leaning on the sidestand and tipped toward the left....the right side (exhaust) cam lobe and rocker may not be getting enough oil.  The lack of air flow over the exhaust also tends to turn the pipe blue.

This rocker damage may have been from excessive idling while on the sidestand and/or the use of car oil in the engine.



Second......the black tube at the bottom of the bike is supposed to have a cap/plug on it.  It is not supposed to be open all the time - you remove the plug when you change the oil, and drain the tube and replace the cap.  Running with the tube open can allow unfiltered air to enter the engine.

Third....if you are getting fuel dripping out this black tube, it is an indication that either your petcock is failing, or your carb has a needle/seat in the float bowl that is not sealing properly and overfilling the float bowl.

Fourth.....do the test on the Raptor and see if it is working.  Here is the link to the test.

Anything the plugs the tube fairly well and doesn't fall out would work.
It is not under any pressure.
Golf tee, shaved dowel, bolt/screw.  Secure with hose clamp.

He told me he wouldn't put a 660 raptor on the s40 because it will cause the crank case to get flooded if I forget to turn off the valve?

If your float sticks, yes the excess fuel will spill into your crankcase.  I turn mine off but have forgot on occasion.  I check the oil before I start the bike to be sure that there is no "extra" oil that I have not put in the bike.
Also, if your OEM petcock fails, the same thing will happen!

The "puke tube" sticks out below the motorcycle close to the ground a bit before the rear tire below the battery.

the puke tube, which comes out the bottom of the air box should be capped otherwise you get oil on your tire, not good for traction.

There are 2 carb vents that shouldn't.  these are no where near the bottom.  your tech may have been thinking of squid bikes that do have overflow tubes hanging to the bottom, but they are small.  and our vent tubes are stuck up into the frame above the carb.

I tested the vacume hose. Man that was hard to get off. No leak there. Checked air filter seems fairly clean. Before I do the cap and prime test is it possible to take only the carb fuel cup off to check for dirt? Would I have to completely drain the tank before doing this due to not being able to turn off the stock vacume petcock? Thanks

Also...my air filter seems dry. But... stinks of gas

Doing an oil change today. Gonna do the oil test on a bussiness car won't have an oil filter available today. Drain the gas now to change to a raptor. Is it normal for the gas to only come out in the prime position?
