This is one instance where the AM clutches work well.

OEM only on the HD filter, but you can get them for $25 on eBay.

Thanks for the tip Shaun. My 394 clutch still works but is worn looking. I was considering buying an AM clutch for it. Good to know they work well

Also glad to hear this, was kinda scared. Are we talking HYWAY clutches?

Found a slightly used oem cheap so I’ll see! Also looking to still get a 90 so just a little bit longer

As I sit here waiting on parts was wondering what everyone’s thoughts are on transfer shape and direction ? Roof of transfers flat, angled pointed towards intake copy factory or whatever just thoughts on it

 

[srcarr52]

I like to make the lowers pretty wide to take advantage of the flow through the piston windows; widening under the bridge primarily on the exhaust side and then making the transfer outlet a little wider on the exhaust side. Thus the new charge doesn't have to do the back bend to get to the exhaust (primary) side of the transfer port opening. Making sure the exhaust side entrance collides with the opposite at 1/5-1/4 the distance from the center of the bore to the intake side. Lay back the intake side opening till it's close the the ring locating pins (394 piston) or until you like the entrance angle (395 piston with central locating pins).

For the roof I like to make the exhaust side pretty flat, the intake side I like to angle up a bit. I'll open the exhaust side 2 deg before the intake. This is pretty much opposite of how they came from the stock, but I've been noticing more newer designed saws to come closer to this configuration.

I can't find any pictures of a 394 right now. I'll try to snap some as I'm porting two right now. For now here is a 2100, pretty similar transfer design.

How much of a angle then couple degrees?

It's pretty hard to measure the roof angle. I'd say around 15 on the intake side, 5 or less on the exhaust.

I apologize friend. that was uncalled for. We all know the reasoning he wanted your 066 and 395 for "testing". That way he could take his time and copy/duplicate everything.

Please forgive me @srcarr52

Whatever it takes to get a race saw built. Those things takes time!

Finished a 394, here are some pictures.

Also interesting... before and after porting weights of the cylinder. A 6% decrease.
