Great running saw.

This is a great running saw now that it has been ported
by 309 Machine. Very professional service and very fast . Both the saw and the service that be is. Seems better with every tank full I run. Will use them again without question.

309 is solid and the saw rips!

309 is the real deal. A true professional in the art of saw work. The customer experience was as top notch as it gets and the saw absolutely rips. Absolutely satisfied out here in the mountains of Tahoe. Thank you 309. Will absolutely be back!

Better than expected!

I mailed in my 462. It was completed very quick and I was without my saw for less than a week. Saw runs great! This is the second saw I’ve had 309 port and I’m very pleased with the work and performance. 10/10 recommend!

MS 500i

Let me start off by saying that I agree with everything on the other reviews to date..... I've had a lot of hand ported saws in the past and was looking for someone that was up to date doing cnc porting. I've seen the difference in the racing world, so I figured there would be a difference here also. I ran Friends new 500i with a 36-in bar and was a little disappointed. I had already ordered a new 500 I. As soon as it arrived I sent it to Mike @309 machine to have it ported. I had already ordered a Max flow air filter kit and an Egan straight shot muffler cover. I ended up running it for 5 days straight with a 28 inch light bar and full comp chain doing storm cleanup in Western North Carolina. I'm not at all disappointed in my new 500i, and I don't think you will be either.....

Ms261c

I loved my ms261c before with just the west coast universal exhaust port but after making the decision to send it to 309 machine to be ported i am just amazed in the difference of my saw. It’s just an absolute animal now! Thanks again!
