I think the most is like .60 but the more compression then the more stress on your crank pistons and rings. Do you have pipes? And when you get high enough on the compression then you will have to run high octane fuel. ID say go maybe .30 over. Quote Link to comment Share on other sites More sharing options...

mpbanshee Posted March 23, 2007 Report Share Posted March 23, 2007 You should be able to take .030" off, and still run pump gas. Anything more than that, and you may need to have the domes reworked. Use a new gasket, and do a compression check when you are done just to be safe. Quote Link to comment Share on other sites More sharing options...

Use a new gasket, and do a compression check when you are done just to be safe. Thats a 10-4. .030 will still allow good squish clearance. Any more and you should have rechambering done which should be done anyway to correct the squish velocity issues with the factory setup. A simple mill is cheaper but will not offer the best performance. Brandon Quote Link to comment Share on other sites More sharing options...

NEVER SATISFIED Posted March 23, 2007 Report Share Posted March 23, 2007 i wouldnt do the factory head.. plus when you go to machining it and then if you decide to buy another stock head both will end up around the hundreds when in fact u can get a used cool head which serves 2 purposesfor around 150.. and u can change the domes out.. just my .02$ .. now im broke Quote Link to comment Share on other sites More sharing options...
baddsheee Posted March 23, 2007 Report Share Posted March 23, 2007 Off the topic, does anyone know how I can measure the head to know how much was shaved off? My compression isn't that high and would like to bump it up. Quote Link to comment Share on other sites More sharing options...

mpbanshee Posted March 24, 2007 Report Share Posted March 24, 2007 Shaving the head will raise your compression, giving you more low and midrange power. You should be able to go to most any machine shop and have them mill .030" off the sealing surface of the head. Shouldn't cost much more than 35 bucks or so... Be sure to use a new gasket, and check clearance once the head is back on. Quote Link to comment Share on other sites More sharing options...
headsup Posted March 25, 2007 Report Share Posted March 25, 2007 I have 06 banshee just got wiseco pro lite pistons stock bore wondering how much can be shaved off my stock head. I have .40 on mine, only good for a few hrs of hard riding then will short out the plugs. i going to try a diff brand of plug, maybe it will help.i use race gas and jetting looks good.
