there's two types of AIS removal kits. TT or Yamaha Kit. I have pictures of the TT kit. In fact, it's in the performance index in the stickies.

We can answer a simple question. Just need to know which kit he used.

Actually, there are a slew of kits for AIS removal. For example, I use the kit from F2 Racing.

If.... you think the AIS kit caused a misfire, the only thing it could be is a vacuum leak, which would be apparent at idle and on decel. That would merely be the point where the vacuum line had connected to the intake side of the head. On the airbox, a failure to plug the port there would enable dirt ingestion. On the exhaust, you'd be getting exhaust carbon' at the point of the leak and probably excessive decel popping.

I strongly suspect your issue is something else unless you are trying to describe excessive decel popping..
Is it worse when the bike is hot or cold?
Steady throttle? Only when accelerating? Low RPM? High RPM?

okay, i think i have the GYTR kit because i have a rubber plug that goes over the intake port and a cap that goes over the exhaust port.

its definately a misfire. 1/4 throttle all the way to WOT. steady throttle. the warmer the bike is the worse the misfire is. if i run through the gears it doesn't do it. ive jetted it countless times....

Then your problem is not the AIS. It is one of two things. Either the bike is too rich on the needle or you have the renowned "WR slow speed miss". Being you state it happens all the way to WOT, I'd lower the needle a clip position, test, lower again and test. See if the problem goes away or gets significantly better. If you have the stock needle in, I beleive on your bike it is non-adjustable. You can either get a YZ450 needle (one size leaner than stock for a YZ) or get a jetting kit from James Dean.

it happens at a constant throttle between 1/4 and wot. what causes the slow speed miss, the cdi?

i'll try leaning out the needle and see how it goes.

The CDI on a WR is sometimes the cause, though is can be jetting too. Being it seems worse when hot, leaning is the correct first 'testing' step.
