My Muffler Mod :)

[Craobh]

I haven't forgotten it Andy, just been fixing a flood of non working kit before takling it:thumbup:

 

There is no confusion over working and racing saws, I do the work that reaps 80% of the power gains and that fits with most peoples needs. The longest running saws I have done are Stubbys 346XP and Burrells 357XP and both have now had a lot of work done with them to much satisfaction!

 

The only saw I have got a bit radical with and gone pop up and full port plus a couple of other extra tweaks is my 357XP and that would just be too expensive in time to do as a standard offering on a working saw.

 

I guess two heads have different thoughts whizzing around in them, that and a background of motorbikes and having watched much racing doesn't help:blushing:

 

Your cool bro .......bet ya would build a racing hot saw if ya were asked and you'd love it???????? lol

Dolmar 116 and a 026. Done some tweaks to a few 200t saws but nothing major as the saw doesn't leave much for porting anyway.

 

Just doesn't float my boat. A short bar does a good job on a good saw. IMO.

 

Plus I have way too much on the bench to have time to port anything. Just about got time to spend at home.

 

But a long bar does a gooder job on a gooder saw.

 

If you do not like to fiddle with mechanics, or you let someone else fix your saws, it makes sense to keep it simple. But when you can spend a little time and have a 44cc saw cut nearly like a 65cc saw, or better, why not? I found a 444SE with a scored piston last spring. I replaced the piston with a milled 346XP OE that had a pop up on it, redid some of the timing and the ports, and ended up with a $60 chainsaw that worked hard all summer clearing trails up in the Pacific Northwest while I was timber cruising. It actually beat a ported 60cc saw at a PNW saw GTG(but some of that had to do with the work I put in to the chain as well). Your work is a lot easier and efficient when your tools are faster and more efficient. Your back will certainly thank you. I now can also carry a smaller saw in my kit and leave more room for other things.

That thing has more chips flying out the front of the clutch cover than I see most 40cc saws put out the back.

 

I really suggest you try a ported 372XP. The way the transfers are done on the 346 and 372 allows a LOT of gains when porting with very little modding. If you play with the ports right, they are monsters, and they last.

My thoughts exactly bud . My 346 and 372 have been ported by spud and its all good !!!

I think it is something you either understand and are in to or something you think pointless.

 

I spent twenty years developing manufacturing processes to run faster, smoother, to be more accurate, more efficient and produce less waste.

 

Nothing was left as standard, process speed rose 30-40%, set up times cut from 1-2 hours to 10 mins and scrap dropped from an awful 5% to under 0.5%.

 

Having spent my youth on bikes and fiddling with cars, it seems pretty natural to take an efficient standard machine and make it go 25% faster.

Spud, you ever modded a 254xp or is there no point?

Not done one to date but would think that it would have plenty to give - the exhaust port looks as though there is plenty to do on it but would need to check dimensions etc.

intresting thread thanks,

just a thoretical question, what saw could be modded to pull a 24" bar comfortably and whats the price comparison compared ie ( new small saw plus modding costs)with the typical larger non modded saw in that bar range??

thanks carl

[TreeswingerPerth]

Looks the part , tidy work !

Done a few 372XPs now, they fly on a 20" and will easily pull a 24"...think you may be going in a bit deep in to this - most just like a lighter saw that pulls like a far heavier one:thumbup1:

[carlos]

thanks spud, basicly what i meant was is it cheaper to buy a small saw and mod it or cheaper to buy larger saw?

thanks
