[MG porting]

On to the other mods...

I enlarged the stock opening and added a screen.

I brazed the holes that I drilled earlier and added some support pieces and brazed those on also.

And, one is never enough so I added a Red97 deflector and an opening to the fly side. Screened it in for safety and stuff.

It's not too bad. My 044 MOFO hybrid is loud.

Looks interesting. I haven’t.

It's designed for the K&N filter that is an HD "upgrade". I ordered a couple of the wraps to see if they will fit the regular HD and winter filters.

I haven't gotten mine yet John. I'll write about them here when they arrive. I think the filter wraps are a nice addition to the HD filter.

Yeap. I use the outerwear pre filters with the HD... but would be interested to see how these one's work

The wraps work really well,my mower uses a similar style. Oil them with UNI filter oil. I pull the wrap and wash it in dish soap every couple weeks. Keep a spare so you always have a clean one.

Geez, it didn't take long for somebody to call the police. I take it you made a clean getaway...

Lol.its funny how the 044s and Ms 440s are louder than the big Saw's the 044 that I wish I never got rid of you could here that thing for miles so I was told by many people.lol.

Nice. I'm hoping to avoid the whole HD filter thing if I can by using one of these and the metal mesh winter filters.

The only saw I have loud enough to get my neighbors to complain is when I mill with my Big Bore 660! So, when I'm close to houses, I try to mill with something else.

I have pretty cool neighbors so that me making noise isn't much of a problem and I normally try to run saw and such at times where I know there not sleeping lol

Great looking & sounding saw!! Should be a great saw once broken in!

K&N is good filter for a car/motorbike for road use but i would be suprised if it would outperform maxflow-filter in saws. I have K&N filter in my car, and it is pita to clean...
I also have a maxflow-filter in my 661 and it is great upgrade. Planning to get maxflow-kit also for my 660.
Dirt bikes use oiled foam-filters, i have not yet seen K&N filter in a dirt bike.....
Just my 2 cents......

Thanks Tom. I'm liking it. Ran it with the 7-pin, but it seems to like the 8-pin.

The motor sounds really good - nice work! Was it starving for fuel a little bit toward the end of your bore cut?

Thanks JJ. Could have been. I was thinking to maybe open the main jet a bit. It's a 61 right now, so maybe it would benefit from being drilled to a 70.

I run them all. Not particularly a fanboy of any, but Dolmars are my favorite. I'm still about 2:1 Husky to Stihl.
