See my sig below, And a 4mil is the biggest you can go with trenching. Edit: you don't wanna bore more than you have too. Boring on a banshee will not gain you anything Quote Link to comment Share on other sites More sharing options...

BlntdEyez Posted November 9, 2008 Report Share Posted November 9, 2008 so just clean up the cylinders and thats it? If your going to kevin he will tell you whether they need a bore or not. Just be sure to send your pistons with the juggs. Quote Link to comment Share on other sites More sharing options...
grizzly700 Posted November 9, 2008 Author Report Share Posted November 9, 2008 im pretty sure they do i only have 105psi on left and 110psi on the right:\ Quote Link to comment Share on other sites More sharing options...
sinisterboo Posted November 9, 2008 Report Share Posted November 9, 2008 yep, only bore when you HAVE to. And any big-bore kit that uses stock cylinders is a bad idea in my opinion. All you are doing by putting big bore sleeves in a stock banshee cylinder is taking away transfer area, which is kinda low to start with anyways.

I have a 68mm big bore kit, and my transfers look like they have plenty of meat left. Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted November 9, 2008 Report Share Posted November 9, 2008 You're gonna have to explain this. I have a 68mm big bore kit, and my transfers look like they have plenty of meat left. Same here. Most of the people that say a resleeved stock cylinder sucks dont actually have one. I have resleeved stock cylinders (patriot drag ported 4 mill) that have the same sleeves. First bore is 66mm last bore is 68mm. Looking at the transfers by eye you cant even really tell. I could see that being the case where you have the huge sleeves that go clear to the cylinder head studs.(404cc). Quote Link to comment Share on other sites More sharing options...
