J-Red Cs2166 mods

[Bro]

Guys, I've done the search, and I'm not really finding what I'm looking for. I'm looking to grind the transfer port panels on a CS2166, and can't find a good thread that explains the process well.. If someone could link one, or give me some direction, it would be greatly appreciated.!!

Thanks,
Brandon

Pull the cylinder and remove the transfer covers, you will need a security torx bit. there is a baffle in them that you need to grind out. I clipped mine out with some side cutters and then used a small sanding drum to smooth them out.

Thank you.!! That seems simple enough. Did you notice a pretty good gain.? I've already dual ported the muffler with a 288 deflector..

I didn't make any cuts with mine before I did it. If you do a base gasket delete make sure to check your squish, Mine was .016 on the outside edge and around .020 on the inside edge of the squish band, not flat.

What's an acceptable squish number.?

Bro , I just did this to my 2166 that I have had for a year and I did a muffler mod and ground the transfers with a base gasket delete and the saw is really nice to cut with now. I cut with it alot today with a 8 tooth sprocket and man o man that thing is sweet.

I was told that I should be ok with .016 so I'm going to leave it for now and see what happens. If I pull the cylinder for some reason I'll cut a little off the piston to get a safer squish number, around .020.

Ronie mine was the same and I ran 3 tanks through it today and I was in some big oak and really working it and that thing couldn't get enough wood to eat. Lol

That's good to know. I've only made a few test cuts with mine and I love it. I made a couple of cosmetic changes to one of mine.

That's nice I like that. What did you use that's oil and gas resistant?

It's a 372 tank dyed with Rit dye.
