RIPPEN Posted December 20, 2005 Report Posted December 20, 2005 This winter I decided to pull off my top end for a re-build since it feels like its gettin tired. Everything has seemed to look real good but Iam just curious whats up with the pistons. I noticed that ring that runs along the edge of the pistion The weird part to me is how it runs along the intake side of one and the exhaust side of the other. I scraped the carbon off the middle of the one to see the #s otherwise they looked the same except for the rings. Thanks RIPPEN Quote
FASTOYS Posted December 20, 2005 Report Posted December 20, 2005 Looks like they were hitten the head to me! Quote
rocketboy Posted December 20, 2005 Report Posted December 20, 2005 looks like yo u were rich and neglected the topend past its service time . seems yo u also did not have enough squish band clearance to me Quote
locogato11283 Posted December 20, 2005 Report Posted December 20, 2005 Looks like they were hitten the head to me! 450056[/snapback] wow it does..id think that would destroy something quick like..wondering if the head was milled or something just a little too much?? Quote
RIPPEN Posted December 20, 2005 Author Report Posted December 20, 2005 I think all it has off the (stock)head was .35. This is the first time I have had it apart and all the mods up untill now were done before me. I know it was way rich when I first got it. It had a 200 main (single carb) I steped it down to 185. It has been extreamly reliable and Its had allot of time on it this year. I didn't even think bout them hitting because I would guess that would take them out right away. Iam glad Iam not the only one that finds this odd. RIPPEN Quote
RIPPEN Posted December 20, 2005 Author Report Posted December 20, 2005 HOLY HELL, Jeff I think your right, damn your good.... I looked closer at the head and I can just barely see kinda the same pattern as whats on the pistons. I can't belive it didn't wipe them out... Damn, Iam glad I asked even though I gettin a different head with the new set up. RIPPEN Quote
BigRed350x Posted December 20, 2005 Report Posted December 20, 2005 I am amazed it didn't crack your pistons or break them. At least you caught it before everything went to hell. You should check your crank bearings and see if they are up to spec. With the pistons hitting the head I would think it would add a lot of stress over time to your crank. Quote
