"..... how can the rebuilders tune the engine any further than we can'.

Errrr...., you may NOT rebuild your Max without it being stripped and RE-Checked (for sealing) by an 'sealing agent. Remember, the 'sealing' process is supposed to include WEIGHING the crank, etc., (so we are told!). Thus, much of what you can do by rebuilding the motor for yourself would be 'lost' by such a 'sealing' process.

Strictly, on a Max, 'tuning' IS banned! It may, however, still occur......

BUT.... assuming it's NOT being 'tuned', a good rebuilder can improve the performance of MOST engines simply by adjusting the component's prosition, relative to each other to ensure everthing aligns beautifully. Think abot how you would re-attach your exhaust, adjusted badly, it'll partially cover the port; adjusted well, it'll give a cleaner exhaust 'run'.

The NEXT trick would be for the 'tuner' to select those components which align BETTER with your existing components. Again, barrels are fractionally different, as are 'exhausts'. If the tuner exhanges an exhaust for one which, by chance alone, matches YOUR barrel better, then you will have a better motor!

I have used the exhaust as a simple example. It may not even be CORRECT for a Max... but it's supposed to be JUST an ilustration!

Think it through and you'll see that there is LOADS to be gained from working through a pile of spares selectin THE best component to match others in your engine.

Now think about the first point! If your 'tuner' has select components that match PERFECTLY and you rebuild it yourself to ALIGN perfectly (at a later date)... and the engine need to be DISMANTLED again to do the sealing...... guess how it' going to come BACK to you after 'resealing'...... unless you use the same guy to re-seal it as you used to 'tune' it.....

So.... 'tuning' is probably the wrong word... but people THINK they understand what 'tuning' means... hence the use of the word, in this WRONG place!
