Modding?

[Sam Thompson]

I have heard a fair bit of talk about "porting" "muffling" and such like on here. I havent really come across (or felt the need to) mod a saw, so I would be very grateful if some knowledgable bod helped me with a few things?

 

Why would you mod a saw?

 

Is it really that much better?

 

How much does it cost?

 

Can you do it to any saw?

 

Im thinking of getting a bigger (MS 460 esc) saw soon, would it be worth modding? Or does it depend on what your doing?

 

Thanks, and sorry for all the questions!

 

 

Sam

read through this link, i found it awesome!

used a brand new husqvarna 346xpg which had been modded the other day (45cc) outperformed my stihl 361 (60cc) so so fun to use!

 

i'll try answer, but only to my limited knowledge

 

Why would you mod a saw? to run bigger bars with smaller, lighter units. faster cutting, fun!

 

Is it really that much better? YES!!! brilliant fun

 

How much does it cost? the saw i used cost £200 in mods

 

Can you do it to any saw? yes

 

Im thinking of getting a bigger (MS 460 esc) saw soon, would it be worth modding? Or does it depend on what your doing?

 

see the link above, 460 turned into a 660 killer, 880 contender!

I've been thinking about this a lot lately too my dad is a bit of a genius with engines and stuff might get him to mod my 440 which is getting old he's got a little 24 laid about somewhere that would be canny with a bit of power

Just to add a quick question cheers, where can we get it done?

i opened up the muffler on my dads old 039, i read a lot on other sites, before i did anything, the muffler exit holes shoudlnt be more than 80% of the exhaust port onthe piston, any more isnt good, I think im about there.

 

Used a dremel with a drill bit and a grinding bit. Making circles bigger and bigger till i felt they were right, make sure you clean up any rough edges and make sure you make it clean inside.

 

Also opened my 260 up slightly, not done it enough to make a difference, sounded slightly different but now its almost no change.

 

I painted the mufflers with black woodstove (high heat) paint after modding, looks nice. After they were rubbed down well with a wire brush and dremel brush to give them a good surface for paint to stick to.

 

the 039 sounds like a scouser on a crosser, razzes its nuts off and sounds cool, lot louder though. It used to run a 16" bar ok, ive put an 18 on it and it runs that well, tested it on some big oak pieces cutting full length, worked well.

IIRC an easy way to mod a 460 660 is to buy an exhaust from the magnum range.

 

They have extra holes and ports compared to standard.

 

They might not offer as much performance but its fairly straight forward to do.

 

I did a slight bit of muffler mod on 46 and 66 but I think not enough to make a difference, think I will have another go soon ish.

 

Oh some new piston rings on an old saw will work wonders. too.

we've an old 044 sitting in the container.

would it be worth stripping her down,

the lad who works for me is fairly good with engines n associated stuff

what would he need to do ???

new rings....ok

magnum exhaust...if i can find one...

 

what else

[armchairarborist]

always worth modding for more performance, my 460 was a bit disapointing when new, but 3mths in i got the stihl exhaust mod minus the spark arrester and bigger dogs, the difference was amazing, revs up faster, cuts quicker and when started at 8am makes people really upset with the extra noise..

quick question in the mix ... would modding reduce the working life of the saw??

just curios as the only modding worth doing to my saw would be buy a new one!!!

cheers carl.

someone once told me it might shorten the lifespan of the saw.. but who cares when its cutting fast..?
