lvnglrg2005 Posted September 16, 2009 Report Share Posted September 16, 2009 My friend and I both ride 1989 Yamaha Banshee's (BRAAAAP!!!) But we were both recently deployed to Iraq servin in the Marine Corps and when we return home in February to sunny San Diego we want to hit the desert season up one last time togethe before he gets out. My Banshee has a few bolt on mods but for the most part is stock. His on the other hand is a 410 stroker motor Banshee and when he bought it, he didn't bother to ask the guy what he had in it. We both have our Banshee's in storage together and no one has access to them but us. When we get back we want to get a fresh rebuild on both but we are having a hardtime finding anyone or anything that can tell us what exactly would make a 410 stroker. We want to buy some nice Wiseco kits to rebuild our motors but neither of us have a clue what we need. I was wondering if anyone could give us some help. Thanks!

You really should tear it down to see whats in there. Or at least pop the head off and get some numbers off the top of the pistons. That would give you an idea of what is in it. There is to many varables. Besides you dont want to order pistons before you have the jugs checked out. What happens if you order pistons then end up needing a larger size? You can get a 410cc banshee by running big bore sleeves and a stock stroke crank. You also need to know if the crank is a long rod crank. You can get specialty pistons for big bore sleeves. Most of the time when running a Long Rod crank ethire stock stroke or 4mill most of the time you run blaster pistons. 4 mill Stroker Crank 66.5mm = 403cc's (last bore on stock sleeve cylinders) 67.0mm = 409cc's 67.5mm = 415cc's 68.0mm = 421cc's Stock stroke Crank 68.0mm = 392cc's 68.5mm = 398cc's 69.0mm = 404cc's 69.5mm = 410cc's 70.0mm = 416cc's Quote Link to comment Share on other sites More sharing options...
