head work after boring

[twostrokin]

I want to bore out my jugs,now I don't really know much bout this so I have a cool head do I have to do anything to the head I was also thinking of just getting the stock head shaved down what's your opinions

[Surfrjag]

if you have a coolhead then you shouldn't have to do anything got the stock one besides sell it or throw it in the dumpster. what size domes do you have?

[twostrokin]

I'm not sure what size they are but ibwas thinking to bump the compression up

[Deadbeat]

how old is the bike and whats been done to it

[twostrokin]

04 hot rods crank coolhead +7 timing advance jetted stock carbs no lid on air box juice box cdi box boyseen reeds pro circuit pipes 12tooth in the front 46 in the rear. The jugs I want to put on are ported and polished no clue who did it or what kinda port job it is. But I just need to know if I bore it do I have to get domes to match the bore size or how does that woek

[twostrokin]

I have 150 psi right now on both sides

[Deadbeat]

150 is pretty healthy

Ok so can I run my cool head with the domes I have after boring or do I have to get bigger domes to match the bore size

If you're not going to a "big bore" size (68mm +) then you should be good to go.

Ok thank u like I said before I no nothing bout boring what are the size of bores to cc. I'm looking to have a 373 or something like that...i hope this kinda makes sense lol

[twostrokin]

It is just a 04 crank the jugs I want to put on are stock bore but I would like to bore them out what would u recommend and why ditch the juice box

[GNR101]

why are you boring them out? 

 

just to make it bigger cc?

[twostrokin]

Yes the power just don't do it for me no more

[Jereme6655]

you don't bore a 2 stroke for power......you gain almost nothing.  You save the bores for when it needs rebuilds......and it will need rebuilds.  Again.....don't bore for power....there is none...........4strokes make power by boring, not 2 strokes.
