oil smells like gas

[84honda200s]

ok guys i went out and checked my oil and it is good but it smells like gas. what could be wrong? im new at these 4 stroke engines.

At one time my 400EX oil smelled like gas when I changed the oil, but haven't noticed it since.

I guess, it's possible, if yout running rich the unspent fumes could be absorbed up by the oil.

Is this on your 200S? Are you still running the snorkel system? Make sure you have a good clean air filter and that the motor can get plenty of air. You may be rich.

Also, if you don't already, try to turn the gas off each time you park it for the day. See if that helps.

i am no longer running the snorkel. i cant be running rich because i checked the plug and its actualy running lean. i always shut my gas off. 3.00 a gal you bet i shut it off lol it has me stumped because i know nothing about 4 stroke engines.

[TravEX]

Have you checked the plug after you run it a few days? Just a thought. Plug checks cen be very confusing.

So you got a stock air box and stuff now, that's good.

Could it be your rings? Just a thought.

I too would like some info on this my self, i'v notice that in my oil to (gas smell), and my spark plug is a brownish color, so it's not burning rich:wondering


I know it's not my rings, because my compression tester says 156 PSI at WOT

[84honda200s]

well im not running nothing on my carb yet lol i dont have a airbox. i may be getting a k&n for it. my plug is almost tan but its not its like a sand color

[TravEX]

, because my compression tester says 156 PSI at WOT

Huh:wondering
What do you mean WOT? Are you meaning that you help the throttle open while doing the test?

[84honda200s]

how u get a reading off a guage at wot ????

[troy]

simple. 3 people where needed here, one to pull the bike over, one to hold the compression test and one to hold the throttle open. It how the service manual said to do it.

[84honda200s]

danm sweet i shoud try that. i thought you somehow got it started while testing lol

[TravEX]

So, your compression was 156 psi. It is usually assumed that you did the test correctly, with the throttle open.

[troy]

the max was suppost to be 149 psi...Kinda makes me worryed about it being that high. see i just replaced the head on it about 3 week's ago..When i first pulled it over it all most broke my hand (little did i know she hit TDC), So i made 100 percent sure my valves weren't hitting the piston, and they weren't...so out came the compression tester.

[84honda200s]

danm. i got thinking on a car if you smell gas in the oil 9 times out of 10 its the cam. now what im getting at is does a trike have a cam or a seal that can go bad??

[TravEX]

I'm gonna sit back and see what others have to say. I'm kinda stumped.

Is it VERY strong smell of gas? or just a hint? Just a hint of gas may not be bad. Dunno.

[84honda200s]

its not strong. its only a hint but ive never had this happen before.

Your floats are sticking open, with the fuel left on it will drain into the crankcase's, Probably Just dirt in there from not running a air-filtre, the rest of your motor must just look Peachy.

Ditto... Calssic small engine problem.

[84honda200s]

so a filter should take care of it?

[threewheelin-feelin]

so a filter should take care of it?
carb needs to be cleaned and turn your gas off when its not being run and see if that helps

[84honda200s]

yea i no about turning off the gas. i will clean it then get a filter i will let you guys know how i make out.

--??? well too much blow by will cause this- ( fuel getting by the rings)
--the needle and seat being wore out-letting fuel flow in the cylinder and -past the rings into the oil
--oil not being changed in a long time
i dont know w t f your talking about -with the cam?-- stuff/it has to get past the rings ,not the cam
