Banshee Pistons,..Stock or Oversize??
I just took apart the top end on my '99 Banshee and I'm not sure how to tell if has been bored or not. I know the stamping on the top of the pistons will tell me, but I do not know waht the #s mean. I have a Clymer manual on the way, but I want to get the cylinders bored ASAP. I purchased a set of .020 over pistons in the hopes that it still had the stock bore. The pistons that came out just have one row of numbers "dot" stamped on the tops. Any suggestions on how to tell what the piston size is?

I already found out. It seems I have wasted money buying .020" over pistons, because the cylinders are already.060" over. But I will save some additional money because the machine shop said they can just hone the cylinders instead of boring. They aren't as bad as what I had remembered seeing them.

running stock pistons is acctually a plus...if you think about it...Yamaha had taken so time to fine tune the engine to run stock...the engine's were not made to run bigger...that is like introducing a animal into a new enviroment. A banshee with a stock bore and the right port job, will beat a ported bike that is 40 over running on alcohol. it all has to do with the port work...
