Porting A 390XP Top End For A Worksaw

[Mattyo]

Mattyo it’s been brought to my attention that you were the one who got me the top end for my saw thank you so my I can’t tell you how much all of this support has meant you all are a great bunch.

I had help a few other guys were in on it...more than I was expecting. Yall know who yar....

All of a sudden I had random dudes offering to toss a few bux in the pot. Was really good of those guys.

Enjoy the saw!

There were several fellers who pitched in to get the whole deal done.

We might raise a little hell amongst ourselves, but when needed, we pull together in a tight unit.

I get that everyone who has helped me I hope I can return the favor one day

The snap/pop in the exhaust note leads me to believe it has slightly more than 135psi of compression.

I was told today by the Husqvarna regional rep that the 390 short block is already been taken away

Bob had Joel fill the combustion chamber with Bubblicious, so it's got more pop than most.

Just found this thread. Seems like this kinda spread across the forum.

Sounds hungry. Good deal

Could be something to that as the system won't accept the part number and backorder it. Currently just says "not available". Have to wait an see where it goes.

It's too bad you can't compost all that swarf Randy.

But we can.... at another bench.... with different things in mind. Swarf adds strength.

Sadly....these very same threads give the crooks a blueprint to build a few good runners too. Then.....the long cocking begins.
That's the main reason I don't post these sort of threads much anymore.

Bob keep me in the loop. If that the case I better get at least one more if you can get any at all

That's what happens when these saws run over 13,200 too long. Too much RPM causes a vibration that loosens the jug bolts, and rattles the muffler apart.



The transfer inlet and the stroke I reckon is the most difference Lee.

395 on the left....

That's what the rep said this morning when I was at the shop, I hope he is wrong and they come back soon.

I have a 2188 that Randy built, bought it from Clint years ago. At 13,100- 13,200 rpm it will pull a 34" bar with full comp chain in oak all day long with authority ! It is my favorite felling saw for larger trees, and it has dropped many many tons of Eucalyptus . Like the name says they are truly outstanding "Worksaws".

 

[Larry Joe]

I'm just sorta tired of it all.

I'm working on an exit plan.....
