Spuds Porting and Tuning Thread

[spudulike]

The software cannot alter the ignition limiter, the limiter is within the ignition unit itself, it is set at 14055 strange number but hat it is should be.

 

I guessed it would be and don't reckon an unlimited coil will be available any time soon!

 

In theory though, it is unlikely the saw will pull much more than 12,000rpm in larger cuts so the unlimited coil will give you nothing!

Looks like we have a 560XP in for porting plus to add a bit of spice, it will be running a pop up piston and some radical compression:thumbup:

 

This saw is a bitsa so it is pretty much anything goes on it. It will be an interesting project!

Interesting do you have a picture of a previous piston that's been machined by chance?

I'm guessing it's an aftermarket piston being fitted? Or have you turned the base down?

9t .325

 

:thumbup:So which chain and how low the rakers ?

It will be both!

This is the 357XP although we increased the pop up size afterwards

I'm so torn between getting an older 357 or a new 560 next

[Eddy_t]

It will be both!

 

 

Beware of the transfer bolts, they're barely clear of the crank on my saw, all I've done is liquid seal the base instead of a gasket!

Just an Oregon chisel chain, the one with the humped drive link. Rakers are about .35 (.404 depth gauge tool)
