IceAlmeida Posted August 1, 2012 Report Share Posted August 1, 2012 hey guys i have a 2005 banshee special edition very low hours and never had a top end done i know there is tons of threads and i been looking into this for abit but i just have a question about shaving the head if i wanted to shave the stock head around .025 - .030 can i just run an indicator along the top get it as perfectly flat as possible and just skim .025 - .030 thousandths off the top without making any other modifications? for the squish and such? also ive never had the top end done and i was wondering if i should just wait to do this modification when i re do my top end ? i also got a adjusting timing plate from charriot if i put it to +4 will i notice a big difference on my 2005 with 290 mains and t5 pipes? thanks everyone for their help and time Quote Link to comment Share on other sites More sharing options...
NetBSD Posted August 1, 2012 Report Share Posted August 1, 2012 i took .030 off my head and added +4 timing on 93 pump gas, woke it up a little bit. i would say go for it and shave the head, they are easy to take off and head gaskets are $10. thats all ive done to my stock engine, no other mods needed when i shaved the head Quote Link to comment Share on other sites More sharing options...

bansheecaptain Posted August 13, 2012 Report Share Posted August 13, 2012 you should be fine a port doesnt change your compression ( correct me if im wrong please ) but with running a port and the added power you should get a welded crank , with all bolt on power you pushing the limit a bit but when you step into the porting bracket then you want a welded crank you dont want to risk not having it . another thing with all that power she might be running alittle hot to without any cooling mods done like a cool head would be a better choice then shaving the stock , inline coolers for hoses , bigger rad , upgraded impeller . all those help Quote Link to comment Share on other sites More sharing options...
