Spuds Porting and Tuning Thread

[Rough Hewn]

Interesting. I'll check with my insurance people next week.

Thinking about sending spud one of my saws.

As a matter of interest, many of the saws I get in for porting have worn brake bands and missing chain catchers etc. These are known safety features and should be checked to make sure they are serviceable regularly!!

 

The point I am making is that the saw may work faster after modification but the safety systems are also returned to full working condition. Also, I tach the saw to WITHIN the manufacturers maximum limit (albeit closer to the maximum than normal) as it ensures engine protection so you have a more powerful saw, operating within the manufacturers parameters with serviced safety features....that's my defence and it is always the users choice to modify or not for competition or daily use, domestic or commercial!

 

I would say that most of my "tuning" customers find a ported saw safer than non ported as it does heavier work using a lighter saw, less fatigue on the body and less time actually cutting!

Thanks spud, I have a very basic understanding of porting. I've read several hundred posts in your porting thread, and I'm quite interested in having you port one of my saws at some point.

Is an 880 worth porting?

Can you put a bigger top end on?

Or not worth it?

Not done much on 880s TBH, I am guessing they are already big and powerful but rarely used. Never seem a big bore for them and don't particularly like cheap Cylinder kits on saws that kick out that much power and will cost £££££ to repair if the kit fails.

 

I tend to service them and get them back to scratch that way - generally they have oiler issues or have seized through old fuel!

Thanks spud, I've never heard of an 880 ported or modded either.

My 261 & 661 are both mtronic, and my 461 is only two weeks old.

I run all my work saws on motomix/aspen now.

Is a 461 any good for porting? Or do I have to buy another saw just to port?

I have done a few now, the owners were happy. It is one of those saws where you make lots of small adjustments rather than real big changes.

On the issue of modded saws and insurance.

 

Chainsaw manufacturers, just like all other industries carry massive insurance against product liability and are happy to stand by their equipment in the form that they supplied it, or with approved mods such as optional bar lengths and different chain types.

 

But in the event that the proverbial stuff hits the fan and an injury was sustained from a chainsaw accident the saw may well end up back at the manufacturer for assessment and you can bet your bottom dollar that they will pick up on any mods and back out of any liability. The injured persons own insurance will follow their lead, leaving liability with the person carrying out the mods.

 

With this in mind most dealers will not fit anything other than genuine parts to machines and not attempt to 'make do and mend'. Its just not worth the risk for a few quid profit.

 

Fitting genuine parts and not straying from manufacturers spec gives us a sound 'paper trail'

 

Just saying, from a dealer perspective.

[Rough Hewn]

Yeah, I thought that would be the case. Thanks for clarifying.
