rave valve question

[Apex06]

ok i got my new engine in the mail the other day and everything looked good until i noticed there was a extra sensor on the head..... do i need to switch the head? or can i just leave the sensor on the top of the head unplugged??

and another question, can i delete the system just by pinching the lines that go to the pod on the top of the valve? or should i use my old valves from the non rave engine....

any help would be great.
thanks, mike

I would be nice to know what your working on exactly. But seeing that you must have a 07 motor because of the lines going to the rave valve, I would not cap those off they are needed. If the engine you took out did not have this style rave you might want to hold up a minute and make sure you have the right motor. IMO

the chassis is a 2004 summit x and the engine is a 2005 800 HO out of a mxz renegade

my chassis isnt set up for it as far as i know and the ecm signals the valves to open up using engine vaccum from a soliniod.

i think ill just switch the exhaust valves out on my old head.

Uhhh, the 05 800HO motor did not have a knock sensor or vacuum raves. You may have an 06 800HO Ptek?

so thats all that sensor is? knock sensor? well tonight im taking the old exhaust valves off and putting them on this engine and pluggin the vacum line off the block and leaving that sensor in just unplugged.
Im sure everything will be fine.

Yep, and you can unbolt the sensor and remove it. That bolt does not go all the way through the head.

Not sure what you mean....non rave engine?? If it has exhaust valves, it's a R.A.V.E. Rotax Adustable Variable Exhaust

 

[Apex06]

both enignes i have have them.... they are under the black cap over the exhaust valve and it seams like both engine only had 1 and that was under the clutch side.

I stand corrected......the 05 800 HO MXZ Renegade does have the knock sensor and the vacuum raves. I did not know that.

#12 says i would need 2? but both engines only had 1 and both on clutch side?

 

[jacmmaxwell]

You need one in each valve, that is what makes it adjustable. The spring holds the valve closed until the correct amount of pressure opens the valves.

It makes no sense to only have 1 spring. Each valve is completely independant from each other. You need a spring on each valve.

 

[Apex06]

nows it all making sence, i found the other spring in the box of junk that came with that sled!
Thanks again guys, Mike

input

If you have the springs on the RAVE valves, other than the two that go between the black cover and the white piston, you have an 800R engine.
