Is this excessive

[cole_robinson24]

I’ve been tinkering with my 025 stihl I got for free locked up. I let it sit for a few weeks with deep creep in it and it unlocked. Anyways, it’s ran great for the last 2 years. I’ve started modding the muffler heavily, I’m wondering if it’s to much for this saw. It runs sweet and makes a ton of power over stock. Let me know your thoughts on it.

I have a MS250 that I've done some work to including a muffler mod. I basically reverted it back to a 025. As long as you've got your carb dialed in you'll be just fine. Keep your chain sharp.
