Holzfformer G372XP

[kram]

I bought this saw in Jan and so far I like it. There are a couple of minor issues but the power is great, to me it feels as powerfull as my buddys Stihl 500i and nicer to use/start. Im using a 20" bar but may get a 28" for the bigger stuff.

 

 

Im thinking of buying a 52mm big bore kit which will take it from 71cc to 77cc and give slightly more power. Parts are cheap if it goes wrong, and I'd then have the original cylinder as a spare.

 

Good idea? Anything to consider when swapping a big bore kit? Will it need any futher tuning or just a quick carb adjustment?

 

Thanks

Is it a Farmtech ?  I have heard other people say they are pretty good for the dosh ...

Those Chinese clones are always rather 'optimistic' when they state hp and cc's.

 

It is unlikely to be anywhere near 71cc already

 

There is a youtube video somewhere which shows you how to check the actual cc of these saws.

Same power as a 500i! Must be something terribly wrong with the Stihl then.

Perhaps, I also had a new sharp full chisel chain and we were cutting a rotten ganoderma ash so perhaps neither were really under much load. The specs claim 4kW vs 5kW... Either way power is not everything and I prefered the g372xp. I'll be fixing the issues and not wanting to use the 500i again. My wrist is still sore!

I would expect the bore, stroke etc to be to the published spec but perhaps the compression may be set lower. It would explain the much easier sstarting

 

 

Anyway the china bashing is no interest to me. For £159 delivered its a great saw that does what I need/want. Can anyone give me advice on the big bore kit (china or otherwise) and any other tuning options I should do while Im in there?

 

Thanks

I seem to remember there was a thread where someone ported the farmtech version of a 372 . It went very well I think .

It’s not just China bashing.

If they produced a brand new design, with innovative features, and put it out at that price (or any price in fact) I’d be interested.

But they steal decades of research and work of other companies, by just copying.

 

I don’t really care that much you understand, buy what you like.

[kram]

Yes, I did. It seems we cant have a sensible discussion about modifying a saw because you dont like where it came from.

 

Big bore kit, yes or no?

Big Bore No.

Why mess with the build (integrity?) of an already cheap saw? 

 

For a bit more than the price of a pot and piston couldn't you buy a new Holzforma bigger saw? G288?

And then get a big bore kit for that 😃
