Spud. Can I have ago at "what's on your bench". With other sorts of motors?

 

Please MATE.:biggrin::biggrin::biggrin:

 

If it fits on your bench then go for it, guess you have some behemoth of a traction engine lurking in your garage:001_rolleyes::lol:

 

Fit it on your bench and take a pic:lol:

 

Rich doesn't like the porting talk cos he fooked his MS260 porting it:blushing:

 

Never mind Rich - you fixed those bikes of yours yet - got a pigging Piaggio to fix soon - flippin Chinese one:001_rolleyes:

Didn't you do a dolmar porting? You seem to mention ideas, but I've not seen pics of the fruits of your labours

I did and the dolmar is still going strong. Sorry but pics is the one thing I always forget as I normally walk out the door and forget the camera as my head is filled with what I need to do that day.

 

It was and it wasn't successfull. There was a significant increase in power but not in speed.

 

Yes the 026 did go a bit wrong as the piston ate itself. But I rebuilt it and carried on. That and tweaking a few 200t saws is as far as porting goes for me, I have enough trouble clearing the machines I get in and being a groundie for d a tree surgeons that I don't have the time for it.

You say about increase in power but not speed, did you raise the exhaust port much? As you used an old torque saw, the exhaust timing is quite late, meaning a longer burn time for more power and lower rpm
