Honest to God my Husky TE450 is stock! Stock gearing (13/50 I think?), Stock intake, stock exhaust, etc... The only mod it has is as follows: I dremelled out the exit port on the muffler (there is a 1" tube welded in to reduce noise, and it cuts air flow as well... I noticed a huge difference in top end performance once I did this...) That's all! I'll be happy to prove it to anyone. Marty Schmid (Goofy Foot) will verify. Let's race! Chris B.
