ClaudeMachining Posted February 23, 2016 Report Posted February 23, 2016 When i bought it, the Kid said he replaced pistons/rings each season and also said that the jugs were sport ported. Never been honed, stock size. I just took some pics, looks good to me for 2006 jugs, will measure the cyl this afternoon. Will map it soon. Quote
ClaudeMachining Posted February 23, 2016 Author Report Posted February 23, 2016 Yup, that look like a nice cleanup job to me. Going to measure the cyl. diameter right now! Quote
ClaudeMachining Posted February 23, 2016 Author Report Posted February 23, 2016 Started to take some measurments, but the probe was too small....Old School ftw!!So i got from 64.05 (perpendicular to the exhaust) to 64.30 (parallel to the exhaust) Quote
ClaudeMachining Posted February 23, 2016 Author Report Posted February 23, 2016 Did you get 54 or 64?? Just edited it...it's 64 of course Quote
Bennett131 Posted February 23, 2016 Report Posted February 23, 2016 64.05 to 64.30 isn't good.That is in mm of corse, so it's less than .008. Not good but I've seen worse. Quote
ClaudeMachining Posted February 23, 2016 Author Report Posted February 23, 2016 Is it usuall to have more wear in the exhaust/intake axis than the other way? I'm buying drveline serval like jugs anyway but I think I will send my oem one for an oversize and keep them as a backup Envoyé de mon GT-P5113 en utilisant Tapatalk Quote
trickedcarbine Posted February 23, 2016 Report Posted February 23, 2016 Yes, think in terms of how the crank/rod/piston motion is. On the down stroke it's tugged down but also the rod is being slung back toward the intake and on th up stroke it's being thrown up, but also a bit toward the exhaust. That's why you see the egg shaped bores on motors with more hours. To help combat that issue, the common solution is a longer for to create less angle so there is less fore & aft thrust. Quote
