more mid/top by retarding ignition timing

Hi. I've got a 98' 220. RB head and carb, vforce reeds, fmf Woods pipe.
I'm looking for a bit more mid to top end power, and I am willing to sacrifice a bit of low end, as I've got pleeeeenty.
Since I can't afford an fmf Rev pipe at the moment, I was thinking about rotating my stater plate one notch to the left (counter clockwise) to retard the ignition timing. What are your experiences/thoughts on this? Some say that there is little effect on a 220 versus doing this on a 200. Is it worth doing?
Thanks

With out putting a rev pipe on it , the gains would be minimal.
Save up for a rev pipe and use the stock silencer
Sell that woods pipe to someone who owns a 200 , they should never be used on a 220

Bro, this. I put the gnarly desert (rev) pipe on yesterday and it added so much top end it overshadows how awesome the bottom end is.

Okay, I'll up the priority on getting a rev pipe.
Once I get the rev pipe, will retarding the timing be a worth while mod as well?

try retarding it to see how you like it.
But to pay Peter you have to rob Paul.
Retarding timing benefits top rpm power but lessens pre-7K power.

I had my 220s ports opened up & matched , the head , carb & piston were also modified by a local 2 stroke guru who knows his stuff.....I told him I wanted a good spread of power throughout the whole RPM range & that's exactly what I got ....he also altered the timing slightly to give me more on top for a little longer which was noticeable ....try it & see you can always put it back if you don't like it.

We run our 220's with a few degree's additional advanced timing. Everything is a compromise and we
don't need over rev. Great pull from idle to wide open.
You have to run good fuel with 220 head work and advanced timing.
