A 2 into 1 exhaust may squeeze a little more out of what you have, also maybe a programable ignition to work with what you have (if you haven't done that yet). sounds like you have a nice combo already.

Not bad for what you have, the problem with chasing HP is those last few HP are the most expensive, and can actually reduce the reliability of the motor. Also many mods will give you more top end HP that looks good on a dyno sheet, will actually reduce HP in the RPM range that you ride in 90% of the time.The best way to get any real HP increase that doesn't kill the bottom end is to increase displacement ...

An 85" kit is simply the largest rebore size for an Evo, bearing in mind they are actually 82" as new. The main benefit that kit gives is increased CR.

You've had the honour of Scott calling by! The simplest and quickest way to get the best out of your bike is to pick up the phone and call him. Advice doesn't get much better or quicker!

Here is what Scott's heads (oem, stage II) and w-8 cam can do with the right pipe and squish. By the way I'm only at .030 the stock bore. I highly recommend you call him......

I was going to have some work done on my twin cam at M and M but sold it. They gave me a very good price quote for a set of cams, pads an tuner an tune.

That needs work, tuning that big dip out would give you that power bump your looking for.
