One of the disadvantages of parking a bike for such a long time. One of 2 things have happened.(Or maybe both.)
Valve stem seals have hardened.
Rings have become gummed up.
Either way you'll need to get the head and barrel off. I've heard of mixing a table spoon brake fluid with a cup of petrol and running that through the carb. I dont recommend it as I've not tried it. Rather try something like valve ease. Dont use it too often. The graphite tends to clog filters. I've also used acetone on my 4X4 but be VERY careful. Use only about a teaspoon full per litre of fuel.

Why does the Acerbis 6.6 gal tank of the 2004 ktm 525 sx not fit the exc

Hi, Fred parts swapping is common with most motorcycles when it comes to interchangeable or compatible parts from one model with another except for CDI's they are year-make-model specific the best thing to do is call your local Dealership Parts Department or a reputable independent shop. If your location is not near a shop then go online and find a parts catalog or "FICHE" and match part numbers depending on your criteria.

What is the fuel mixture for a 2002 KTM 300 EXC 2 stroke? Thanks

WIth Shell v-power and your favourite 2-stroke oil, you could go 50:1 (that's from my dealer). I have been running 50:1 since my 2002 300 EXC has been new, always use new mix for every ride, and drain whatever leftover is in the tank every two weeks.

Can i restrict a ktm 525 to 33 bhp

yes. like any bike your local dealer can restrict it for you.
i would question why you would want to restrict the 525 when it would be easier to get a 250 and restrict that instead. the difference would be much less noticeable and you wouldn't feel like you were riding a castrated bike. i'd wait for your licence upgrade to get a 525. or just do your accelerated access in the mean time and get the 525 in it's natural form. if you can afford a 525 you can afford accelerated access.

2009 KTM 250 exc-f excessive oil use, no apparent oil leaks or blue smoke

It is normal for these bikes to use some oil. A typical, maintained 250 4 stroke will use a pint of oil or more in one day of riding - depending on a lot of variables, of course. Oil consumption on these four strokes is quite typical.

I have a 2005 KTM 525 SX that burns alot of oil, and makes blue smoke, but still has lots of compression and power, I'm just wondering if it would be piston rings or Valve problems?

Could be the valve guides, or it could be the rings are worn, or not aligned properly.

What was the actual compression reading?

It wont start

well it could be because the bike sat for a while. with the 2 stroke gas being mixed with oil sometimes when it sits the oil sinks to the bottom and it will clog the valves fuel lines carb every thing. you should check.
