You mentioned you don't like loud mufflers. Here's a trick you can use on those mufflers with the bolt tubes through them - turn them into outlets.

DO NOT stick a grinder through the exhaust port hole and grind a hole in the side of the tubes. That will allow the exhaust to blow straight out the bolt tube. The best way takes a bit more work, but allows a quiet muffler - you drill in from the side of the muffler with a drill bit the size of your Dremel bit. Then drill a hole in the side of the tube AWAY from the exhaust port. Then open up the hole in the tube. The easiest way is to shine a light from the opposite end of the tube while you work the Dremel bit. You can watch the bit as you open up an elongated slot in the tube. Then put a weld or braze over the drill hole on the side of the muffler.

You could do one muffler with that mod and compare it to one of your dual ports and check both the sound and power output to see if the mod was worth doing to the other saws.

Thanks I've been playing around with different design's for years i will try that these mufflers are just 3.80 a piece lol I've got a few extra.

$3.80 for a muffler... I'd probably pay more than that for a freaking muffler BOLT.

Gawd, the price of saws and parts in Oz is so over the top. I mentioned how I was looking at getting a Makita 6100, except they want A$1,200 for one, plus a goods and service tax of 10% on top of that. - A Husky 562 is A$1,700 plus tax...

They really make you guy's suffer it's ridiculous what stuff cost there i know it's not a 6100 but these are rebranded dolmars 329.99 free ship amazon in the us a hell of a deal maruyama mcv51 i think it's called.

 

[Czed]

That's 900.00 us for a 60cc saw i can get a 390xp for that money crazy.

 

[Terry Syd]

Compute using the Husky 562 (plus 10% GST) and the price A$1,876 - or US$1,398. That will buy a lot of Chinese saws...

I was interested in the Dolmar 6100 as I think it has a lot of potential with the reed valve in the strato system. However, I'm unwilling to pay that much just to play with an engine. I've already got enough saws to cut wood.

Beat up used 372s for 350-450 us is the reason i bought these china saws i bought two new for the price of one even with the mods I'm still under 300.00 on each saw.
With a little work these are very good running saws i know some pro builder's are going to build some of the kit 372s curious to see what gains they get i'm keeping mine I've got another big bore on order.

Thanks for the advice.
I finally got some time to work on my 50mm i took a egg shaped carbide burr and cut a 1/2 inch hole in each tube facing the center of the muffer the hole's are midway through the tube offset from the top exhaust tube's
It's a very good increase in torque and overall power it's very impressive at least to me and my friends lol
Next i will do the same to the big bore 372 thanks terry I've thought about that mod but never tried it
A little louder but very tolerable.

Put another 1/2 gallon through it today hard ash is some tough stuff it hasn't softened yet from rot it just zips right through with that chinese chain I've got more on order good stuff I've got stihl rs on the big bore i can't tell any difference when cutting.

 

[Czed]

Here's a piston pic when i worked on the muffler looks new the black feels like grease and wipes right out of the exhaust.

 

[Czed]

Is there a chance that you could get a long term update in the future on the kingpark saw you sold?

The guy i sold the king park to has run two gallons through it he brags on it all the time lol
I told him to bring it to me if he has any problems.

 

[Czed]

Used an egg shaped carbide bit to cut the hole's in the dual ported mufflers worked great it even helped the anemic hl supply topend.
That saws getting a huztl big bore when it shows up.

 

[Czed]

Anybody got a china saw or one in progress.
I could've sold all of mine even to my stihl head friends that have tried them out they keep trying to buy them lol
If they follow through and order their own i will post pics to see if there is any difference between mine and theirs they want me to mod them.

Is that something funny in the exhaust port? Kinda in the bottom right corner. Maybe just a reflection

Top of my fence post i know it looks odd lol

 

[Czed]

Got another huztl big bore worked up to replace the hl cylinder.
I wasn't going to touch anything but the intake and exhaust was full of casting residue.
i didn't change port timing but i did grind this out enlarged the exhaust side's a little and cut the ring off the bottom .80 under the jug simple stuff.

 

[Czed]

The big bore ring is stamped hy and the cylinder plating resembles the hyway plating I've seen before i don't have a hyway to compare.

 

[smokey7]

Are you seeing any tension issues with the hyway rings.

 

[Czed]

I've only used a few hyway rings and one maybe two stihl cylinder kits never had a issue they usually had 150 comp and they haven't been brought back by customer's
I've bought a lot of the huztl rings no problem either.
