Hey fellow Pegasonado's...
Well it's taken about 8 weeks but my stage one mods are complete and I am thrilled with the results.
For anyone interested, here's what I've experienced. Hopefully this will assist you in deciding what to modify (if anything).
Bike: 05/06 Pegaso Strada
Akrapovic Carbon cans
A snorkel cut down
Mod 1: Akrapovic Cans
Baffles in and standard
Sound: way too quiet (quieter than stock)
Power: no real improvement.
Surging improvement/smoothness: slight
Worth it?: No
Baffles modified (mesh at either end removed)
Sound: Nice sound - inoffensive
Power: Some improvement, better throttle response.
Surging improvement/smoothness: Noticeably better
Worth it: Aesthetically and sound yes, power no.
Baffles Removed (looks MUCH better)
Sound: Initially VERY loud but gets quieter when carbon builds up and is now acceptable for all but long cruises.
Power: Very good improvement in toque, acceleration and over-rev. When you first ride with the baffles out you think the difference is good but not great. Then when you replace the baffles you realise how much better it goes without them.
Surging improvement/smoothness: Much better (almost as good as with PCIII)
Worth it: Definitely (and it looks trick and saves a lot of weight)
NOTE: When running pipe without baffles you MUST block off the AIS (Auxiliary Induction System). If you don't do this the backfires and popping sound like a gunfight in downtown Bagdad.
Mod 2: K&N Filter
Power: slight difference.
Worth it: On its own - probably not. With pipes - yes because you need to get good flow of air both in and out of the motor so a pipe without a good flowing filter is a little pointless and vice versa.
Mod 3: Cut back snorkel.
Sound: More induction growl
Power: Some improvement to throttle response
Surging improvement/smoothness: Improves both.
Worth it: Yes - it's free!
Mod 4: Air box vents
Installed 5 airbox vent holes with micro foam filters. Adds about 2 sqaure inches of breathing area.
Power: Hard to tell (not much I'd say)
Surging: No difference
Worth it: In isolation no. Part of the stage 1 - probably it cost very little
Mod 5: PCIII
Power: BIG difference in toque and power. The difference between hard to wheelie in 1st gear before - now fairly easy to wheelie in 2nd (no clutch).
Worth it: Absolutely
I kinda wish I'd done all these mods at the same time so that the change would have been more dramatic rather than the incremental changes I experienced. However, my friend who rode it before has ridden it since and got to feel all mods combined. He couldn't believe the difference. It has gone from a plodder to a real little weapon and I get a real buzz out of riding something that I think is now performing to its potential.
I have purposefully left the cost of the mods out of this because it was / is not about money. It is about whether it was worth the effort and the satisfaction of the result. Whether it's worth the money is probably more a function of how much money you have and what else you could spend it on.
I got a really really good deal on my bike so even with the cost of these mods I am still way ahead. If I had paid full retail I may have thought twice.
When I get it on a dyno in the next couple of weeks I will post the results but the proof of the pudding is in the riding and it rides great.
