Great class!!!!!! I would have done better in school if you were my teacher. Me and the system was never on the same page lol. Appreciate you sharing some of your knowledge with us. 👍💪
Yes on the taper/chamfer on the exhaust side of piston! When I got my first dominant wiseco piston years ago it was like that. I’ve done that to all the saws I build now. But not too much
Good on you for putting your thoughts out there and helping us all learn. The only known drawback to domed a piston is efficiency losses do to slowed burning. However with increased compression and charge velocity into the combustion chamber, this helps negate much of those losses. At least this is how I understand it.👍
I sure do appreciate you making these informative videos. Thank you. A question I have is, How do you know when it's okay to tune a ported saw, or any saw really, to higher than manufacturer recommended max rpms? That's what I've been tuning to. Actually a little under sometimes seems to produce a little more torque. Do you just trust your assessment of torque? i.e. if it's too lean it bogs down too easily and if it's not bogging down let her run high rpms? Or is there something else I don't know about to keep an ear on?
