How many licks does it take to get to the center of a tootsie pop?

i have been running a 1995 701 61x jug that had a rod let go and put back together with pistons outta the back of Smitty's friends pickup truck on its original bore. I could not guess how many hours on the bore but the used pistons looked pretty good when we dug them out of the truck's bed. FYI i am boring it out as soon as my pistons come in. I don't want to push my luck any more.

Thats totally disgusting,thanks
a friend of mine has put approximately 1025 gallons of fuel through his bone stock '90 sj that hes owned since it was new. thats roughly 500 hours of riding time. we removed his cylinder about a year an a half ago to replace the base gasket. it still had factory-fresh looking cross hatches from the honing that yamaha did in 1989 and absolutely zero marks on the pistons or cylinder walls. i guess it all depends on your riding habits and maintenence.

thats incredible, my cylinder was very very glazed looking and had some vertical scuffing from wear?? or water ingestion? I hope i can get another 12 years out of the new bore:biggrin: i can't afford to do it each decade:banghead:

do seapoo's have nikasil cylinders? if so whats the deal with those, are they meant to have the rings replaced every year and hope to never have to bore? I had a kx125 that i ended up re sleeving with a normal type of sleeve that could be bored. How long is the life on a typical nikasil bore compared to a regular one? anyone know?
yes, rick... its paul..... and he uses yamalube

No Seadoos are not nikasil they are cast iron borable cylinders,the yami 800 and 1200 have nikasil and so does the kawi ultras and the sxr800.Its not that big a deal really you just send them to Us Chrome and they redo them for about $130.00 each
Those 6m6 650 engines are bullet proof, I know a guy who has 91 & 93 waverunners and they have never been apart. He runs quicksilver outboard oil from Walmart and they still run like champs. I would think that the small exhaust port has a lot to do with ring / piston life on these engines.
Until compression drops noticably.
