big bore kit

[groomzybanshee]

i have been thinking about puting a 404cc big bore kit in my banshee. I know every body says save your money and get it ported but why cant you just get the big bore kit and get it ported??

You can. People will claim that your wasting money. They will say that the big bore isnt worth it because it makes the transfer ports smaller. Yea it isnt the most economical choice but what do you do if you want bigger cc's with out the drag porting of a cub?

 

I got a set of Patriot Racing drag ported 4mill cylinders. I got them for pretty cheap. 100 bucks. They needed resleeved. I sent them back to Patriot Racing to have them resleeved with bigger sleeves. My bore starts out at 66mm. and ends at 68.5mm. 66mm bore with the 4mill stroker crank is 400cc's for me.

 

If I was in your situation I would do a 4 mill stroker crank AND get the cylinders ported for the 4 mill crank before I would do the big bore sleeves. It will end up costing about the same, and it will have a ton more midrange do to the extra stroke.
