If you rev it and hit the rev limiter there's a good darn chance it will shoot flames. The rev limter cuts the spark, but you're getting the same amount of fuel. The flame is the excess fuel burning off. As to running 8 discs and no spark arrestor there's no need to. The disks don't do anything without the spark arrestor.

Dude dont get all white trash with your stuff. The rev limiter is there for a reason.

Oh great flame blaster, I too am one of the ones that spits fire! I give unto you 92 octane plus or VP racing fuel so you can scare the crap out of everyone behind you! add a turbo and your only 3 cyl. away from one of those Subaru Rally cars!
Hear me Roar and watch me as I shoot fire out my tailpipe!

Yeah it's when it's hitting the rev limiter. Put the spark arrestor back on. Thats why it is called a spark arrestor, it arrests sparks which cause the flame out the pipe. You only ever want to ride with the spark arrestor out at a MX or tt track, other wise you run the risk of catching stuff on fire. I was running witout it but it looks like I am going to have to put 3 or 4 more disks in, sadly that kit is $30 for extra disks.
If your getting flames without hitting the rev limiter something is wrong, either it is dumping massive amounts of gas into the head pipe (which it would flood if so) or the timing is off, if it's only the pipe and jet you did, just put the spark arrestor back on. The poping that a lot of people have been talking about with the White Bros pipes is due to no spark arrestor.
