robert.b.west Posted October 12, 2007 Report Share Posted October 12, 2007 The bike place near me charges $125 to mill a head and I was wondering how much you would take off to run about 105-108 octane. I think that I could probably get it done for about $50 at a local machine shop. Also what type of tolerances do they need to hold as far as flatness across when setting up the head.

Snopczynski Posted October 12, 2007 Report Share Posted October 12, 2007 Shit, another $125-$135 and you can get a cool head with o-rings and domes. Then you can change compression for future upgrades, and if your motor ever grenades, you just throw new domes in it. Not to mention it will help keep the motor a little cooler. You can even sell your stock head on ebay and make some more money off that. Quote Link to comment Share on other sites More sharing options...

WALLACE84 Posted October 12, 2007 Report Share Posted October 12, 2007 Holy shit!! $125? a guy I know does it for $30. I think your best bet is to get .030 taken off Quote Link to comment Share on other sites More sharing options...
robert.b.west Posted October 12, 2007 Author Report Share Posted October 12, 2007 One more question how hard it is to install the cool head? Do I have to change the studs? Quote Link to comment Share on other sites More sharing options...
WALLACE84 Posted October 12, 2007 Report Share Posted October 12, 2007 You have to change them on a Pro Design head but not a Noss Head. They are real easy to put together Quote Link to comment Share on other sites More sharing options...
06BaNsHeE Posted October 12, 2007 Report Share Posted October 12, 2007 IMO all the local shops charge more than any big name builder.My local shop ripped me 100 for shaving the head.When I could have bought a shaved head already for 50$ on ebay.

shee rips Posted October 12, 2007 Report Share Posted October 12, 2007 i wouldnt pay more than 50 bucks to get the head milled unless you are getting it rechambered. i got mine milled .020 for 30 bucks by the old guy down the road. Taking off .020 put my squish at about .035 so i dont know if you would want to go much farther than that. there are other people that are more knowledgable about this than me though.

Snopczynski Posted October 12, 2007 Report Share Posted October 12, 2007 19cc is about 169-175 psi compression. You can run 50/50 94 and 110 to get 102 octane which is ok! Quote Link to comment Share on other sites More sharing options...
