how big and how much

[skinindustries]

I was wondering if you bore out a banshee how big can you go? can you do .80 over,with out hurting anything? And if you mill the stock head will you have to get high compression pistons? or can you run stock ones? any light on this question's would be awesome.

You can go to .100 over but.. thats scary.. .080 is still considered safe.

 

Only bore them enough to clean the walls.. You wont get any real gains from the bore itself.

 

Usually the norm is about .020 off the head.. I wouldn't go anymore unless you rechamber the dome. I think thats still safe for premium pump gas. No such thing as hi-compression pistons in the banshee realm.

So if i bore and mill i wont see any real good gains?? What would be the best bang for my buck? I have toomey t-3 pipes and thats about it. dont want to spend alot on like a cub motor or a 4 mil. setup kinda wanna stay as close to stock as i can. but once i get called back to work i wanna make a sleeper banshee.

compression has a good gain.. but the Bore will be minimal.. Best bang for the buck is going to be a port job. If your completely stock.. then there will be some lil mods that would compliment the porting. Reeds, Timing, compression, air filters. ect..

Well i run a open airbox. i might get an adjustable timing plate. see what that does then get back to you guys on the next mod.
