So I have a 2016 raptor 700 and I've been hearing ais delete and even saw that cuervo racing makes a plate to delete it but I have no idea what that is or were it's located in the bike. I'm doing the big 3 here soon and would like to know if it's something I should delete or even worry about thanks.
I don't have a 2016 so I don't know details. If you order the kit you'll be able to figure out where they go. The AIS is on the front of the head/block, there are a bunch of rubber hoses running to and from it
It is a valve that lets filtered air into the head to decrease emission readings. It can cause a popping on decel which usually points to a lean condition. It has also been attributed to a low rpm "stumble". To remove it completely, the valve is removed and the plate installed, disconnect the electrical connection to the solenoid and tie the wire out of the way, remove all the associated vaccum lines and the solenoid. If you are going with the fci for your intake, the 15+ version will have a hole that you need to cap, the 06-14 would work as well.
what do you do with the reed valve assembly? remove it? keep just the rubber bit? i left mine in and from what i can tell the valve plate just sits there freely. seems weird to me. thanks
Well really, they don't. The reason atvs aren't legal in most states for on road use is because they are not emission compliant. The new head, like pretty much all the rest, come to the raptor off a street bike only sold outside the u.s.
Oh that's interesting, I always thought it was because of the straight axle. I'd rather have a street legal quad with emission controls than a strictly off-road one without emission controls
I wouldn't worry about environmental crap with a raptor. The raptor engine is a fraction of the size of even a small car engine, and the AIS doesn't do much to clean up anyway. It's not like a DPF on a diesel that catches everything, it's just something small they put on to make it pass
Yeah I don't care either. I've been to a tractor pull and when you se those black clouds .... meh if they are having fun why can't I? Let idiots drive prius. I'd like to block it but I don't really know which one it is. If someone can poit it out I'd be grateful. You can use this link to all the parts Raptor 700 2016 part list
If anyone is interested that is and Kharkiv model V-2 (Displacement 38.8 L) from T-34 soviet tank. In its natural aspirated state it produces 500HP. If I recall correctly it has 1200HP with those two turbos bolted on. Its just crazy.
I've played some spot the difference game and I've found few things that are different to 2010 engine on the intake and on the head. I just don't know which one is it :/
There's a bunch of hoses running to and from it, I don't mean to sound dumb but it's not that hard to spot. The head is pretty simple, just look for what doesn't belong
You remove everything from the intake tube up to the head including the solenoid valve and simply install the plate and plug the fitting on the top of the intake tube.
The installation instructions are at he bottom of the page.
Old thread I know, I originally came here looking to see if people remove the AIS hose that runs to the intake tube and what exactly do you use to plug that hole in the tube?
Also, it seems like you guys are fairly confident that the AIS blockoff plate should reduce popping on deceleration but it seems like it's worse now that I've installed the plate. I have a monster exhaust with the FCI. Should that still be happening?
I took all of the hoses off to include the AIS solenoid and zip tied the wires out of the way. Use the plug for the intake fitting. I have some decel popping due to the slip joint for the pipe. The decel poping will not hurt your motor.
