Just wondering how the new 450 is stacking up against the old 350. I have a 350 that has seen borderline commercial use and has never skipped a beat (not even a loose muffler!). I would be curious to hear how they compare from someone that has used both. The 450 has a few nice features the 350 doesn't. It has a quick release top cover, a more secure air filter setup, and a fuel level window. The only downfall I see is the single bar stud. How is the power from that strato engine?
