Re: 636 oil and airbox
and a motor makes vaccum at idle and at a steady rpm the vaccum will drop under accel but will return at a maintained rpm
and with the pair mod there will be a vaccum at the crankcase because of the reed valves that are under the plates on your valve cover ,they are ported to the exhaust and are designed to create vaccum not pressure and this along with the fact you are no longer getting that hot oily air is why you get a hp gain from doing the pair mod because it causes a vaccum in the crankcase and only gets clean air [clean air mod]....

Re: 636 oil and airbox
an f4i lying on it side will pump oil into the air box i have seen it many times and the fact that we all run extra oil and usually bypass our tip over switch makes the problem worse because the bike doesn't always shut off when the bike os on its side or even up side down

Re: 636 oil and airbox
it's about a 5 dollar mod that gives you better power and protects your motor and it only takes like twenty minutes to do so why not do it......
the stock t can be used if you just unplug and cap the vaccum line that goes to it and you only really need about 1 foot of hose if you just connect the two factory lines [the one from the pair valve to the crank case vent tube]

Re: 636 oil and airbox
the throttle bodies are sucking in air when the bike is running so it causes a vaccum in the air box and thats where the crankcase vent tube is from the factory along with the drain tube ..
and a motor makes vaccum at idle and at a steady rpm the vaccum will drop under accel but will return at a maintained rpm
and with the pair mod there will be a vaccum at the crankcase because of the reed valves that are under the plates on your valve cover ,they are ported to the exhaust and are designed to create vaccum not pressure and this along with the fact you are no longer getting that hot oily air is why you get a hp gain from doing the pair mod because it causes a vaccum in the crankcase and only gets clean air [clean air mod]....

Re: 636 oil and airbox
I can talk **** for the simple fact that I have never had oil running out of my bike from being 12ed or flipped. You have also told me your self that the 636 is a easy bike to ride alot more than the F4i. This is why everyone jumped on the band wagon to get one , so they can try and be the next AC... that MF came from over seas road your bike for a day a placed @ stuntwars? Can he have done that on the F4i? If so, he would have road kennys,Alex, or mine. Im shure he could of had Todds Bulle or a F4i if he wanted. When you come from that far away to win you ride a 636 safe and easy

Re: 636 oil and airbox
you clearly don't understand what the pair mod does and plugging your drain tube into your motor does nothing but hide the fact that you are getting oil in your air box i could type all day to try and get you to understand but that would be a waste i think so i will stop trying ...
peace out..

Re: 636 oil and airbox
If you hydrolock your F4i. Wait a while,,,,Put in in 5th/6th gear and push/ roll it backwords for a few min when it feels smoother try starting. if it wont keep trying. It will work I have done this a few times. Im sure the old man will dissagree with me though for the fact that you can bend something. I dont have time to take a motor apart.
