No, they can both be vented to atmosphere, they dump a bunch of toxic fumes back into the intake for EPA and noise.

Interesting....
I agree with the rearward vent going to top of valve cover, but I thought the front vent tube going to the electronics down front was the air intake temp sensor, and this MUST be into the air intake trac as the ECU gets its info from this.
I already have my CAI made but would be a good thing to know for everyone.
thanks!

No the IAT is on the plenum. They are using the same boost and WG solenoids they did on the 1100’s. This is just a boost dump, when we did CAI on the 1100’s these never got hooked into anything.

What specifically is that front vent tube connected to on the front electronics? Does that not send data to ecu?
thanx

No, the ECU send data to it. It’s just a solenoid.

Thanks.....I guess we were all so worried about hooking up these vent lines and sounds like they dont do much.lol

They will spew a film of oil inside the engine bay. Run them into the intake.

Mine was done awhile ago. Dont think anyone else is making their own kits but a few of us here.

Hey Dan, send me a free cai kit and I won't tell people all the bad names you called me when you learned I ordered my 17 sidewinder

No "they" will not. The vent off the valve cover can push oil over time as you get blow by. But unless this engine is less durable than the Suzuki 1100 it takes a lot of time at high boost to see any of this. I would still vent it off the clutches. The other one will push 0 oil as it never gets there. Too much mis information at times, just because some member is peddling a product and trying to make a buck doesn't mean they know that they are talking about.

My comment was from my experience with a K&N filter kit for the RX-1 back in 03. Not for a vendor selling anything today. Instead of running the crank case breather hose into one of the filters, the kit came with a little filter to cap off the line. In time, it got saturated with oil and eventually allowed oil mist which did get all over the engine bay. I assumed one of the lines on the Sidewinder was for the crank case ventilation.

Yes, the line from the top of the valve cover is a breather. The other is a dump off the waste gate control solenoid. I will likely pipe that into my intake so it does not get covered in snow dust and potentially freeze up. On the 1100's we didn't but the solenoid was in a different place, much closer to the exhaust. I do not like to pipe the breather into the intake for the reason you site. If you look at he stock set up the splooge would just end up in the foam. I do not want that into a metal pipe or into my K&N. If you dump it in behind the K&N into the metal pipe or silicone it can be sucked through the turbo or just coat the inside of the intake tract with oil. I am looking for a small catch can to mount on the belt guard for that to hook into.
Anyone ever test with just removing airbox lid or making a vent or air horn right to side panel?

I have been told that works and the AFR is similar to a CAI. I actually looked at just cutting the forward facing side off the lid and covering with Frogskin, would look like a hoodscoop! I do like opening up the area by taking out the stock assembly to let more air to the clutches. I will have under $90 in mine with a real K&N, K&N prefilter, a silicone 90, and a joiner with ports. Did it all from Amazon. Can't seem to get a deal on a K&N anywhere, it's 70% of the cost.
I did see one company is just using the pre-filter only, no foam or K&N style filter. Probably fine for snow and would lower the cost substantially.
