i can feel a couple of then, but just barely.

you can more than likely hone it and be fine............put a new piston{weisco} and you sould be good to go.

thanks, should i get it honed at a shop or use a scotch brite pad?

Scotch Brite... a shop hone will ruin the plating.

yep......never hone.

What? :|

thanks, so all i have to do is get a left side powervalve, and the main one, and a top end kit

you can hone.....IF you have the right hone.....but most people do not use the right hone.......i know i said hone........but i got the thinking, everyone is not me and if you use one from a cheap auto parts store, chances are, you will ruin the plating, or hone to much. the 'safest' way is to use a scotchbright pad, and youll be good to go.


and to tydev95..........yes, just get a wiesco piston, and youll be good. the reason you want a forged piston is.......over time your bore will wear, and you need more clearence for a forged piston, hint, you already have you clearance... just trust me.

lol. "just trust me"??

Did you sneak over there and mic his bore when we weren't looking? If not, it's pretty impressive if you can look at a fuzzy photo of a cylinder on the internet and say "hmmm... yep, that's worn out just about right for a wiseco"


Um, no. Not buying.


Hard to tell from the pics, but the bore looks worn. Have it measured before you go slapping a new top end in it. Excessive cylinder to piston clearance leads to piston slap, worn skirts, and eventually premature failure. I doubt kdxmaniac will foot the bill for those repairs simply because you chose to trust him.

Wiseco doesn't make oversize pistons. The tolerances are in the rings. A Wiseco will fit an A or D bore... doesn't matter.

who the hell are you??? ............let me clear up something here...what is you daily job? and how many bikes do you own AND OR work on? i know what im talking about when it comes to engines. dont really care what you think........mister YOULIED......or whatever your name is.

assuming it's the stock bore, wouldn't a wiseco designed for the stock bore fit it? on the 220's people say to put in a wiseco even if the bike hasn't been run, due to the risk of the piston shattering. and thanks for the tip about the cylinder being too worn, i'll maybe take it to a local machine shop and have it measured.

you do relize this is a plated cylinder right? the plating is a few thousanths thick..........if it was wore "out" it woul be bare, peeling in the bore on the front and back where the skirts rubs..........and i never said anything about a overbore piston??? a stock bore forged piston has to have more clearence than a cast piston, because a forged piston swells when its warmed up, and if you dont have the clearence right, you will seize the piston........yes i know this. and also make sure you check your ring end gaps as well.

i get what kdxmaniac means, and if the bore is still in spec then i'll get a wiseco, i heard they are a lot better than cast pistons. and my dad's friend who's been an auto/motorcycle mechanic for 15 years said the lines on the cylinder walls were just ring marks.

go look at the [bore ar not to bore] forum.........look at the picks i put on there of cast pistons...........this is just a FEW of the cast pistons i have pulled out of bikes over the years.........now do you want a cast piston in YOUR bike????? all of these bikes{pics of pistons} got a weisco piston, and ran for years..........

i think i'll get a forged piston

Lot of people run cast pistons without problems

if you get a weisco piston, ........the "hone" size is on the box.....your bike is a 66mm bore, so the cylinder bore should come up to around 66.0018 or 66.0020

if you get the shop to hone the cylinder, make sure they use a rigid or brush type hone........NEVER use a ball type hone on a plated cylinder.....or a rock type "cheap" store bought hone!

yea, alot of people dont have bikes with 240lbs compression? and 800hp boosted small blocks in there car either! try that with a cast piston........i not going to take a chance on a cast piston in a $12,000 engine in my car......and besides........why would you want to stick a cheap cast piston in your engine after spending all that money and time on your bike? i know your just kidding me anyway.."i hope".....about the cast pistons anyway?

kdxmaniac, the site won't let me send pm's because i'm not a supporting member, but im from massachusetts.
