Spuds Porting and Tuning Thread

[wyk]

Right, my verdict is it spits some chip out! It's hard to say if it was worth it, maybe for racing, but the effort required when it'll be used for day-to-day cutting, I highly doubt!

 

I do it on all my big bars. Not just for a bit quicker chain, but more for plunge or boring cuts. It makes the cut much faster and far less vibration.

 

 

Not as drastic an effect on larger bars, but you can see how it would cut down on the vibration.

Back to porting the 560, the shaping, polishing and grinding is done now

I didn't widen the exhaust port much due to some slot-things on the piston, but I did reshape the uppers!

Unfortunately reassembly has to be put on hold as I've lost 2 bolts for the intake, so I'll have to get the muffler done and finish the engine in January.

Yes, it's a big pipe, didn't look that big until I fitted it into the muffler it's all reassembled now, big filter fitted, the lot! Now to run it and see if I've cocked up, or made a belter!
