Banshee SE Posted January 5, 2015 Report Posted January 5, 2015 My cousin was putting together his motor and he just realize pistons have a difference, same part number tho. What you guys think could be this a problem. Sent from my iPhone using Tapatalk Quote
Surfrjag Posted January 5, 2015 Report Posted January 5, 2015 No problem.. How are you running 64mm pistons thats pretty rare Quote
Banshee SE Posted January 5, 2015 Author Report Posted January 5, 2015 Thanks!! He just open the motor to replaced rings like PM and found this piston with rings pretty cheap off ebay so he get it installed. Sent from my iPad using Tapatalk Quote
Surfrjag Posted January 5, 2015 Report Posted January 5, 2015 Measure ring gap. It can tell you quick if its not right 1 Quote
m671054 Posted January 6, 2015 Report Posted January 6, 2015 No concern of engine vibration? Wouldnt you want to check piston weight since those holes appear to be very different. 1 Quote
JayLow Posted January 6, 2015 Report Posted January 6, 2015 Most likely they are balanced to get the correct weight.. Quote
registered user Posted January 6, 2015 Report Posted January 6, 2015 wiseco changes little shit (and sometimes big shit) on their pistons more than most people change underwear. some of the honda stuff has changed numerous times in the last couple years. i think the top numbers are the forging numbers and bottom is a partnumber Quote
banshee4mil Posted January 11, 2015 Report Posted January 11, 2015 those are for weight balancing, but you could call wiseco just to make sure,the number is on the web and they are nice ppl and will help if possible -maybe weigh them ,if ya aint got a scale hit up the local drug dealer or takem to your fav grocery store see if they weigh the same Quote
troyzstang Posted January 11, 2015 Report Posted January 11, 2015 Have to agree Carlos. May want to hit up the local drug dealer and throw them on his triple beam Quote
n2otoofast4u Posted January 11, 2015 Report Posted January 11, 2015 You will never notice the difference with the different weight. Run it. Lots of motors out there with mismatched bores with no ill effects. Quote
trickedcarbine Posted January 11, 2015 Report Posted January 11, 2015 Have to agree Carlos. May want to hit up the local drug dealer and throw them on his triple beam Can I come?I'll bring the hookers. 1 Quote
registered user Posted January 11, 2015 Report Posted January 11, 2015 those are for weight balancing you meen for weight reduction those pistons are from seperate batches. probly a early style and later style. the top numbers are either the forging number or maybe a batch number. like i said before wiseco changes shit more than people change underwear. suprised theres no coating yet. they put that stuff on some of the newer pistons Quote
banshee4mil Posted January 13, 2015 Report Posted January 13, 2015 weigh them and find out, they are matched from factory for weight and balance if 1 is heavier its no longer balanced is it Quote
trickedcarbine Posted January 13, 2015 Report Posted January 13, 2015 Not matched for balance from the factory. Weisco is not mocking two pistons up and balancing them. If they were, they would be packaged as pairs with left and right specific markings. Quote
